01H119 - Walter 19/64" SST+ Stub Drill Bit with Hex Shank

Heavy-Duty Precision for Industrial Drilling

The Walter 19/64" Hex SST Stub Drill Bit (01H119) is an industrial-grade cutting tool designed to solve the common frustrations associated with standard jobber-length bits. Engineered by Walter Surface Technologies, this bit features a robust stub length (also known as screw machine length) profile. This shortened design significantly increases the torsional rigidity of the bit, making it far more resistant to snapping or bending under heavy load. It is the preferred choice for maintenance, repair, and operations (MRO) professionals who require reliability when drilling into tough alloys.

One of the standout features of this drill bit is its 135° split point geometry. Unlike standard 118° points that tend to "walk" across the surface before penetrating, the split point bites instantly upon contact. This self-centering action eliminates the need for pre-punching, even on curved surfaces or round tubing, ensuring precise hole placement every time. The bit is coated with Walter's exclusive bronze SST surface treatment, which enhances heat resistance and lubricity, allowing for smoother drilling and extended tool life in demanding materials like stainless steel and aluminum.

Designed for efficiency, the hex shank is a critical addition for modern power tools. It ensures a positive lock within the drill chuck, preventing the bit from slipping or spinning during high-torque applications. This feature, combined with the stub length, makes the 01H119 exceptionally capable in confined spaces where a standard length drill would be too cumbersome. Whether working on sheet metal, thin-walled tubing, or general fabrication, this Walter SST drill bit delivers clean, burr-free holes with maximum efficiency.
