DoTwistBall Indexable Endmill

DoTwistBall indexable endmill from Tungaloy America is an ideal tool for die and mold, as well as general engineering. Combined with a rigid clamping mechanism, the insert’s unique twisted shape improves chip evacuation for stable machining and long tool life in roughing operations.

There are two standard inserts for DoTwistBall: a high-feed type and a radius type, both are interchangeable on the same tool body. The DoTwistBall comes in three varieties: shank type, bore type and modular type. Large pockets on the cutter body deliver even chip evacuation to avoid recutting, extending tool life in deep slotting and pocketing.

Inserts are available in two grades: AH3135 for general materials, including steel and stainless steel, and AH120 for hardened steel and cast iron.

DoTwistBall will significantly boost productivity for customers seeking an efficient machining solution in roughing components, such as die and mold.
