Drill Chucks Most common devices used for holding straight-shank cutting toolsMost contain three jaws that move simultaneously when outer sleeve turnedHold straight shank of cutting tool securelyTwo common types
I. Key II. Keyless

Key-type
Three jaws move simultaneously when outer sleeve turned
Tighten with keyDifferent size keys for different size chucks

Keyless Chuck loosened or tightened by hand without key
Precision keylessHolds smaller drills accurately

Drill SleevesUsed to adapt drill shank to machine spindle
if taper on tool is smaller than taper in spindle
Drill Socket Used when hole in spindle of drill press too small for taper shank of drill
Used often as extension sockets

Tapping head A self reversing tapping mechanism that
feeds into the tapped hole under spring resistance thus allowing the inward feed to be governed by the pitch of the thread being tapped. A reversing mechanism actuates at the bottom of the hole thus removing the tap like unscrewing a bolt.

Arbor The Arbor hole of the An arbor is a cutter
holding device with a taper shank to fit the spindle taper machine: the short or long shaft end is used to mount and drive one or more cutters. having holes that fit on to the arbor. Arbor is used on Horizontal Milling Machine.
