01H112 - Walter 01H112 3/16-Inch SST Hex Shank Stub Drill Bit

High-Performance Walter SST Stub Drill Bit

The Walter 01H112 3/16" Hex SST Stub Drill is engineered for industrial professionals who demand precision and durability. Designed specifically for drilling through sheet metal and thin-walled materials, this drill bit features a robust stub length geometry. The shorter flute length significantly increases the rigidity of the bit, drastically reducing the likelihood of breakage under torque or side-load pressure. This makes it an essential tool for high-volume fabrication environments where downtime due to tool failure must be minimized.

Equipped with a specialized bronze SST surface treatment, this drill bit manages heat generation effectively, extending the tool's life even when working with tough materials like stainless steel. The 135° split point geometry is a critical feature for accuracy; it allows the bit to self-center immediately upon contact with the workpiece. This eliminates the need for pre-punching or pilot holes, streamlining the drilling process and ensuring clean, burr-free holes. The 1/4" hex shank ensures compatibility with a wide range of power tools, including impact drivers, providing a secure grip that prevents slippage in the chuck.

Whether utilized in stationary machines or portable drilling applications, the Walter 01H112 delivers consistent performance. Its ability to handle non-ferrous metals, mild steel, and stainless steel makes it a versatile addition to any MRO inventory. The compact design also facilitates drilling in confined spaces where standard jobber-length bits cannot fit.
