01H010 - 5/32 Inch SST Stub Drill Bit - 135 Degree Split Point

High-Performance Drilling for Confined Spaces

The Walter 01H010 5/32" SST Stub Drill is engineered to deliver exceptional durability and precision in industrial maintenance and fabrication environments. Designed with a "stub" or screw machine length, this drill bit offers significantly higher rigidity compared to standard jobber length bits. This increased stiffness minimizes deflection and vibration, making it the ideal choice for drilling into tough materials or when using hand-held power tools where stability can be a challenge. The shorter flute length also makes this tool indispensable for working in confined spaces where standard bits simply will not fit.

At the tip, the 01H010 features a precision-ground 135° split point. This aggressive geometry allows the bit to bite into the material immediately upon contact, effectively eliminating the "walking" or skating phenomenon often encountered when drilling round stock or sheet metal. This self-centering capability removes the need for pre-punching, streamlining your workflow and ensuring accurate hole placement every time. The bit is particularly effective on thin-walled materials, producing clean, round holes with minimal burr formation.

Walter Surface Technologies has treated this bit with their exclusive Bronze SST surface coating. This treatment enhances the tool's lubricity, reducing heat generation during the drilling process—a critical factor when working with work-hardening materials like stainless steel. Whether you are drilling mild steel, non-ferrous metals, or stainless alloys, the Walter SST Stub Drill provides the efficiency and longevity required for professional MRO applications.
