■ General Feature

The SEC-Boring Bar Series is a collection of SEC-Small

Diameter Boring Bars, a product we began selling in

1976 which continues to be popular today, steel/carbide

shank holders with a highly rigid head design, SumiTurn

X Bar which includes a vibration control mechanism, and

optimized insert grades and chipbreakers.

Complete Support For Boring Operations For Turning

Assists evacuation of chips

Evacuation of long chips

High rigidity rib

New head design

Strong cross-section withstands high cutting forces

Evacuation of short chips

Flattened weight vibrates with

opposite phase from the chatter

and dramatically reduces chatter!

X bar cross section

Direction to which vibration generates during cutting

New vibration control mechanism X Effective Chattering Killer System

■ Characteristics

■ Steel Shank Type

With Vibration

Control Mechanism

● Compatible with a wide variety of tooling

Stop boring / bottom facing / through boring / profiling

● Minimum machineable diameter: CKB model ø 1 mm–, C-SCLC model ø 5mm–

● Vibration control boring bar, SumiTurn X Bar

● Carbide short shank is compatible with turret lathes even without cutting (C15M-STUP model,

C20M-STUP model)

● Insert grades and chipbreakers compatible with a wide variety of work materials

● Dramatically improved chatter resistance, especially effective for rough machining of deep holes

● Achieves low cost machining for large diameters/deep holes, shank diameters up to ø32 mm

are in stock

● High chip evacuation performance, evacuates chips with double chip pocket

● Types with oil hole are in stock

● Holders for negative inserts (shank diameter ø25–ø50 mm) are in stock

Machining methodBar type

Vibration control may not work correctly if the area near

the “ “ label is clamped (due to containing

the vibration control mechanism).

Therefore, the minimum protrusion length is set at 3.5 D

(3.5 times shank diameter).

Cutting speed: Vc = 20–200 m/minDepth Of cut: ap = 0.1–2.0 mmFeed rate f = 0.1–0.3 mm/rev 

Note: The actual amount of protrusion able to be machined

depends on the work material, tool condition, and

cutting conditions, etc.

● Achieves deep hole machining of L/D = 6 for machining diameters greater than ø32 mm.● Negative chip design reduces corner cost.● With different combinations of a large selection of chip breakers, handles a wide variety of process, from rough cutting to finishing.
