Boring Tools Series
■ General Features Since its launch in 1976, our industry leading Boring Bar Series with its steel/carbide shank holders and high rigidity heads has since included the popular Small Diameter Boring Bars and now the SumiTurn X-Bars with it's anti-vibration mechanism, optimized insert grades and chipbreakers.

■ Features of Boring Bars
● Applicable to a wide range of applications such as Stop-Boring/Bottom Facing/Through-Boring/Profiling ● Min. machining diameter: ø1mm for CKB Type, ø5mm for C-SCLC ● Anti-vibration boring bar SumiTurn X-Bar ● Carbide short shank type usable on turret lathes without shortening (C16M-STUP, C20M-STUP) ● Wide selection of insert grades and chipbreakers available for various work materials ● Higher anti-chatter capability for effective rough boring of deep holes ● Achieves low-cost boring of large diameters and deep holes, with ø32mm shank now in stock
■ Steel Shank Type with Anti-Vibration Mechanism
● Excellent chip evacuation with double chip pockets ● Bars with internal coolant hole are also in stock ● Negative insert holders (shank dia. ø25 to ø50mm) are now in stock

●
Clamping a shank on the “ ” label-affixed portion may disturb normal functioning (due to built-in Anti-Vibration mechanism). Therefore, minimum tool overhang length is kept to 3.5D (shank diameter x 3.5). This is a dedicated turning tool. It cannot be used as a rotating tool.
