01H110 - Walter 5/32 Inch SST Hex Shank Stub Drill Bit for Stainless Steel

Premium Industrial Drilling Performance with Walter SST Technology

The Walter 01H110 5/32" Hex SST Stub Drill is engineered for the rigorous demands of industrial fabrication and maintenance environments. Designed specifically for professionals who require precision and durability, this drill bit leverages Walter's proprietary SST (Super Speed Tip) technology. The bit features a robust bronze surface treatment that significantly reduces friction during high-speed drilling operations. This thermal management is critical when working with work-hardening materials like stainless steel, ensuring the cutting edge retains its hardness longer than standard high-speed steel bits.

One of the standout features of this model is its stub length (screw machine length) configuration. In industrial settings, minimizing tool deflection is paramount for accuracy and tool life. The shorter flute length of the 01H110 provides exceptional rigidity, virtually eliminating the flexing and snapping often associated with jobber-length bits when substantial feed pressure is applied. This rigidity makes it the ideal choice for drilling out spot welds, rivets, or creating pilot holes in heavy-gauge sheet metal where stability is non-negotiable.

Efficiency in the workshop is further enhanced by the 1/4" hex shank design. This feature allows for rapid tool changes and compatibility with a wide array of power tools, including standard drill chucks and impact drivers. The 135° split point geometry is a critical specification for precision fabrication; it allows the bit to self-center immediately upon contact with the workpiece. This eliminates the time-consuming step of center punching and prevents the bit from "walking" across the surface, thereby reducing scrap rates and surface damage on expensive materials. Whether used in stationary drill presses or portable power tools, the Walter 01H110 delivers consistent, burr-free holes in mild steel, non-ferrous metals, and stainless steel.
