01H111 - Walter SST+ 11/64" Hex Shank Stub Drill Bit for Stainless & Sheet Metal

Precision Drilling with Walter SST Hex Stub Drills

The Walter 01H111 11/64" Hex SST Stub Drill is a high-performance cutting tool engineered for professionals who demand precision and durability. Designed specifically for drilling into thin-walled materials such as sheet metal, mild steel, and stainless steel, this bit solves common problems associated with standard length drills. The "stub" or screw machine length significantly reduces the overall length of the tool, providing exceptional rigidity. This increased stiffness minimizes deflection and vibration during operation, leading to cleaner holes and a drastically reduced risk of bit breakage, even under heavy load.

At the tip, the drill features a sophisticated 135° split point geometry. This self-centering design bites into the material immediately upon contact, eliminating the need for pre-drilling or center punching. It prevents the bit from "walking" across the surface, ensuring accurate hole placement every time. The bit is treated with Walter's proprietary bronze SST surface treatment, which enhances heat resistance and lubricity, extending the cutting life of the tool when working with tough alloys like stainless steel.

One of the standout features of the 01H111 is its hex shank. This design element makes the drill bit compatible with a wide range of power tools, including standard drill chucks and 1/4" quick-change impact drivers. This versatility allows operators to switch between drilling and driving tasks rapidly, improving overall workflow efficiency. Whether used in a stationary drill press or a portable hand drill, the Walter Hex SST Stub Drill delivers superior hole productivity and a burr-free finish.
