Designed to deliver clean slots with steady, predictable performance, this short-series drill offers reliable rigidity in shallow passes. The Weldon shank ensures secure clamping, minimizing runout and enhancing dimensional accuracy during precision slots and shoulders. With its cobalt-based HSS-E composition, it stands up to heat and wear, making it well-suited for aluminum, copper, and other non-ferrous materials. The 40° helix and 20° rake angle optimize chip evacuation and finish, helping you achieve smooth surfaces and consistent dimensions in demanding applications.
