HIGH FEED MILLING Q & A
Scarring on colletts that spun in the
pocket.
COLLET & NUT STYLE TOOLHOLDER CAREModern CNC machines feature high-capacity tool changers that automatically swap toolholders in and out of the spindle as needed, by means of a high speed swing arm or a rotary carousel. Periodically, toolholders should be examined for wear and if necessary replaced to maintain cutting performance. New operators should be taught how to properly evaluate toolholders so they can recognize when toolholders need to be replaced to prevent premature cutting tool failure, or even expensive damage to the spindle. Many operators do not know why it is necessary to replace their tooling, or have the experience to tell when it is time to do so. Determining if toolholder components need to be replaced is not a difficult task, but does require that the operator knows what to look for. This article will cover the criteria used to evaluate collet and nut style tool holders, describe when and why it is necessary to replace them and the implications of not replacing them.
Example of a collet and nut style toolholder
Parts of a ToolholderA general understanding of toolholder components and their functions is important. There are four main parts to a toolholder (also known as a collet holder or collet chuck).
Pull StudsThe pull stud screws into the top of the taper of the toolholder. Some pull studs are hollow, to permit coolant to flow thru the toolholder. When in use, the pull stud is held by the clamping set inside the spindle which pulls the holder up into the spindle mouth. A spring-loaded draw bar pulls the holder into place. Check the pull studs periodically for signs of wear, cracks, or other damage, and replace any
that are not perfect or a dangerous situation may result.
Pull Studs (also called retention knobs) are extremely important because they keep the toolholder in the spindle. Using worn pull studs or using the wrong pullstud for your machine may cause the toolholder to suddenly fly out of the spindle during operation, causing an unsafe situation for the machine operator
TaperThe taper is the conical shaped area of the toolholder that enters the spindle when changing the tool. An 8 degree taper automatically centers the tool into the spindle. The taper is accurately ground to a tolerance of .0002” for both the taper
tolerance and outside diameter tolerance. Some toolholders like HSK have a shorter taper than BT or CAT style.
V-FlangeThe v-flange is the part of the toolholder that the automatic tool changer locks onto when moving the tool from the tool changer to the spindle and back again. The flange is visually identified as the “V” groove found on the outer most diameter of the toolholder.
Collet Pocket & NutThe last part of the toolholder is the collet pocket, into which the collet is inserted before being secured by various types of collet nuts.
Spindle Mouth WearA worn spindle can cause runout issues that affect toolholder accuracy and reduce cutting quality and productivity. This is a condition known as bell mouthing. If toolholder issues can be eliminated by bench checking total indicator runout, then the source of the problem is often a worn out spindle mouth. A trained professional will be required to check and repair bell mouthing.
Evaluating Toolholders for Wear A worn out toolholder will not provide good accuracy and will quickly wear out your cutting tools. Worn tooling can also cause poor surface finish, and may even damage your spindle.
Taper WearCheck the tapered part of the toolholder for signs of wear or damage where it contacts the spindle mouth. Any problems with the taper will have a direct effect on machining accuracy. If there are any imperfections on the taper, the toolholder should not be used. A worn taper causes an out-of-round condition when the holder is inserted into the spindle. This is called “runout”. Runout causes premature tool wear and excessive vibration during operation. This vibration can cause poor surface finish which may require additional operations to correct. Vibration can also cause heat build-up in the spindle and damage spindle bearings
FrettingIf noticeable marking is evident on the taper a condition called fretting may be occurring. Fretting happens when two steel parts (holder and
spindle mouth) are rubbing against one another. Fretting is visible as small copper colored pits or marks on the taper. This is evidence that the toolholder is becoming worn. Fretting can be mistaken for rust, but it is not. Once noticeable fretting develops the toolholder should be replaced.
ColletsCollets are manufactured from softer metal than toolholders, allowing them to “spring” and tightly grip the cutting tool. As a result, they will wear out faster than the holders will. Worn collets will cause cutting tools to fail prematurely, costing manufacturers thousands of dollars in preventable costs. Collets should be replaced whenever wear is evident so the accuracy and performance of the cutting tool / toolholder assembly is maintained. If there is any damage to the outside or inside diameter (I.D.) of the collet it must be replaced. Look for scoring marks in the I.D. where cutting tools may have spun in the collet, causing damage. Once damaged, collets cannot grip the tool shank effectively, so holding power and accuracy are reduced.
Preventive MaintenanceTo insure proper performance of your toolholders, overall cleanliness of toolholder, collet pocket, collet, and nut must be maintained. It’s important to remember that all these components are manufactured to perform within tolerances of ten-thousanths (.0001”) of an inch. Any dirt, dust, oil, chips, or other contaminant left on the spindle, taper, flange, collet, collet pocket, or nut can cause poor T.I.R. (runout) leading to premature wear of cutting tool, toolholder, and spindle mouth. We recommend a regular preventive maintenance program be implemented in your shop to protect your investment in cutting tools, toolholders, and collets, and reduce scrap.
Mearsuring T.I.R
Fretting (wear marks) on toolholder
taper
Spindle wipers are the best way to prevent contaminants from building up in your spindle mouth.
Use tightening stands and a torque wrench every time you change out a collet or pullstud. Proper torque is essential to collet & nut toolholder performance.

Parts of a ToolholderA general understanding of toolholder components and their functions is important. There are four main parts to a toolholder (also known as a collet holder or collet chuck).
Pull Studs
The pull stud screws into the top of the taper of the toolholder. Some pull studs are hollow, to permit cool-ant to flow thru the toolholder. When in use, the pull stud is held by the clamping set inside the spindle which pulls the holder up into the spindle mouth. A spring-loaded draw bar pulls the holder into place.
TaperThe taper is the conical shaped area of the toolholder that enters the spindle when changing the tool. An 8 degree taper automatically centers the tool into the spindle. The taper is accurately ground to a tolerance of .0002” for both the taper tolerance and outside di-ameter tolerance. Some toolholders like HSK have a shorter taper than BT or CAT style (see illustration)
V-FlangeThe v-flange is the part of the toolholder that the au-tomatic tool changer locks onto when moving the tool from the tool changer to the spindle and back again. The flange is visually identified as the “V” groove found on the outer most diameter of the toolholder.
Collet Pocket & Nut
The last part of the toolholder is the collet pocket, into which the collet is inserted before being secured by various types of collet nuts.

Preventive MaintenanceTo insure proper performance of your toolholders, overall cleanliness of toolholder, collet pocket, collet, and nut must be maintained. It’s important to remem-ber that all these components are manufactured to perform within tolerances of ten-thousanths (.0001”) of an inch. Any dirt, dust, oil, chips, or other contami-nant left on the spindle, taper, flange, collet, collet pocket, or nut can cause poor T.I.R. (runout) leading to premature wear of cutting tool, toolholder, and spindle mouth. We recommend a regular preventive mainte-nance program be implemented in your shop to pro-tect your investment in cutting tools, toolholders, and collets, and reduce scrap.
A program that includes cleaning and checking your spindle, toolholder tapers, collet pockets, collets, and nuts with every use will go a long way towards improv-ing your CNC machine performance and protecting your ROI.
Regularly bench checking the T.I.R. of your collet & nut toolholder assemblies is also recommended to identify toolholders which are wearing out of spec. It’s impor-tant to use a tightening stand and torque wrench to properly tighten pull studs and collet nuts to maintain shop safety and prevent premature damage to collets and collet pockets due to over-tightening. To prevent contaminants from entering the collet pocket, we rec-ommend using inexpensive Black Gold rings to seal the pocket during operation.
Summary
The most cost-effective way to increase your CNC machine productivity, reduce down-time, and reduce scrap while maintaining part quality is proper care and use of your toolholders. Toolholders are a small pro-portion of machining costs, but can have a big impact on productivity and ROI.

Parts of a Toolholder
A general understanding of toolholder components
and their functions is important. There are four m
ain
parts to a toolholder (also known as a collet holder or
collet chuck).
Pull Studs
The pull stud screws into the top of the taper of the
toolholder. Some pull studs are hollow
, to permit cool-
ant to flow thru the toolholder. W
hen in use, the pull
stud is held by the clamping set inside the spindle
which pulls the holder up into the spindle m
outh. A
spring-loaded draw bar pulls the holder into place.
Taper
The taper is the conical shaped area of the toolholder
that enters the spindle when changing the tool. An 8
degree taper automatically centers the tool into the
spindle. The taper is accurately ground to a tolerance
of .0002” for both the taper tolerance and outside di-
ameter tolerance. Som
e toolholders like HSK have a
shorter taper than BT or CAT style (see illustration)
V-Flange
The v-flange is the part of the toolholder that the au-
tomatic tool changer locks onto w
hen moving the tool

For Collet & Nut Style Toolholders
General Overview
Modern CNC m
achines feature high-capacity tool
changers that automatically swap toolholders in and
out of the spindle as needed, by means of a high speed
swing arm or a rotary carousel. Periodically, toolhold-
ers should be examined for wear and if necessary re-
placed to maintain cutting perform
ance.
New operators should be taught how to properly eval-
uate toolholders so they can recognize when toolhold-
ers need to be replaced to prevent premature cutting
tool failure, or even expensive damage to the spindle.
Many operators do not know why it is necessary to re-
place their tooling, or have the experience to tell when
it is time to do so.
Determining if toolholder com
ponents need to be re-
placed is not a difficult task, but does require that the
operator knows what to look for. This article will cover
the criteria used to evaluate collet and nut style tool
holders, describe when and why it is necessary to re-
place them and the im
plications of not replacing them.
Sizing Toolholders
A typical size description of a toolholder is CAT40 x
ER 32. The “CAT” refers to the flange type, “40” is the
taper size, and “ER 32” is the type and size of col-
let that fits into the pocket. The other dimension to
be aware of is the “Gauge Length”. This refers to the
distance the toolholder extends from the face of the
spindle (see diagram.)
Toolholder Care & Maintenance Guide
Example of a collet and nut style toolholder
There are different types of holders that have other means of hold-
ing the cutting tool, such as shell mill arbors, end mill holders, and
shrink-fit. This article deals with collet & nut type holders.
Careful measurement of toolholder dimensions may be necessary for
exact replacement if the part number or description has worn off.

Spindle Mouth WearA worn spindle can cause runout issues that affect toolholder accuracy and reduce cutting quality and productivity. This is a condition known as bell mouth-ing. If toolholder issues can be eliminated by bench checking T.I.R., then the source of the problem is often a worn out spindle mouth. A trained professional will be required to check and repair bell mouthing.
ATC Alignment IssuesIt’s crucial to maintain proper ATC swingarm align-ment. If the ATC does not insert the toolholder per-fectly damage to the spindle and toolholder may re-sult, in addition to poor cutting tool performance and reduced tool life.
Evaluating Toolholders for WearA worn out toolholder will not provide good accuracy and will quickly wear out your cutting tools. Worn tool-ing can also cause poor surface finish, and may even damage your spindle.
Taper WearCheck the tapered part of the toolholder for signs of wear or damage where it contacts the spindle mouth. Any problems with the taper will have a direct effect on machining accuracy. If there are any imperfections on the taper, the toolholder should not be used.
A worn taper causes an out-of-round condition when the holder is inserted into the spindle. This is called “runout”. Runout causes premature tool wear and ex-cessive vibration during operation. This vibration can cause poor surface finish which may require additional operations to correct. Vibration can also cause heat build-up in the spindle and damage spindle bearings.
T.I.R. (total indicator runout) is the measure-ment of axial deflection of the cutting tool in the toolholder assembly. Techniks toolholders are manufactured to minimize runout and extend cut-ting tool life.
You lose 10% of cutting tool life for every “tenth” (0.0001”) of runout

FrettingIf noticeab
le marking is evid
ent on the taper a cond
i-tion called
fretting may b
e occurring. Fretting happ
ens w
hen two steel p
arts (holder and
spind
le mouth) are
rubb
ing against one another. Fretting is visible as sm
all cop
per colored
pits or m
arks on the taper. This is evi-
dence that the toolhold
er is becom
ing worn. Fretting
can be m
istaken for rust, but it is not. O
nce noticeable
fretting develop
s the toolholder should
be rep
laced.
Co
lletsC
ollets are manufactured
from softer m
etal than tool-hold
ers, allowing them
to “spring” and
tightly grip the
cutting tool. As a result, they w
ill wear out faster than
the holders w
ill. Worn collets w
ill cause cutting tools to fail p
rematurely, costing m
anufacturers thousands
of dollars in p
reventable costs. C
ollets should b
e re-p
laced w
henever wear is evid
ent so the accuracy and
perform
ance of the cutting tool / toolholder assem
bly
is maintained
.
If there is any dam
age to the outside or insid
e diam
-eter (I.D
.) of the collet it must b
e replaced
. Look for scoring m
arks in the I.D. w
here cutting tools may have
spun in the collet, causing d
amage. O
nce dam
aged,
collets cannot grip the tool shank effectively, so hold
-ing p
ower and
accuracy are reduced
.
Co
llet Nuts
In order for the toolhold
er to be b
alanced and
main-
taining accuracy while m
achining, it must have a b
al-anced
nut. Many m
anufacturers use bearing nuts w
ith their collets. H
owever, since b
earing nuts have moving
parts (nut, b
earing race, bearings) they are d
ifficult to keep
balanced
, and p
rone to seizure if the seals fail.
We
recomm
end
using “P
ower
Coat”
nuts instead
. P
ower C
oat nuts are balanced
and p
rovide 75%
more
holding p
ower on the tool shank, p
roviding increased
accuracy and
rigidity that is necessary w
hen machin-
ing under sid
e loads. B
ecause they are balanced
and
more rigid
they extend cutting tool life significantly.
Pull S
tuds (retentio
n knob
s)The p
ull stud is a critical safety com
ponent b
ecause it m
aintains the connection betw
een the spind
le and
the toolholder. If that connection fails, the hold
er will
dangerously fly out of the sp
indle.
Check the p
ull studs p
eriodically for signs of w
ear, cracks, or other d
amage, and
replace any that are not
perfect or a d
angerous situation may result.
