Multifunctional TungBore-Mini Tool Provides Better Chip Evacuation in Small Bore Operations

Iwaki, February 2021 — Tungaloy has expanded its multifunctional turning and boring capabilities of the TungBore-Mini line by adding boring toolholders that accommodate its unique XOMU inserts. 

TungBore-Mini is a multifunctional drilling and turning tool line that integrates the capabilities of drilling, OD, and ID turning tools. Its unique XOMU insert features an innovative geometry incorporating a large inclination angle on the cutting edge that produces light cutting, compared with standard ISO positive turning inserts that are typically used for ID turning or boring operations. In addition, TungBore-Mini’s insert and pocket have a dovetail interlocking design providing better insert clamping and stability than standard screw-down insert clamping, ensuring process security during various applications. 

The latest toolholders incorporate innovative designs that ensure secure ID machining processes. The toolholder is designed to provide an ample clearance between the tool and the hole surface through which chips that generated during boring or ID turning are smoothly evacuated out of the small diameter bores. In addition, with Tungaloy’s angled screw fixation method, an engaged screw not only presses the insert against its primary support on the bottom of the insert, but also pulls the insert into the pocket wall. This design also allows a longer screw to be used providing strong insert retention and process security. 

The new toolholders are available for minimum bore diameters of either 10 mm or 14 mm, with either a steel or carbide shank. Total of eight toolholders have been added.
