01H005 - Walter 5/64 Inch SST Stub Drill Bit - 135 Degree Split Point

Precision Drilling for Industrial Applications

The Walter 01H005 5/64" SST Stub Drill is a premium cutting tool designed for professionals who demand accuracy and durability. Engineered with a heavy-duty "stub" or screw machine length, this drill bit offers superior rigidity compared to standard jobber length bits. This increased stiffness virtually eliminates the risk of breakage, making it the ideal choice for high-torque applications or when working in confined spaces where tool flexibility can lead to failure.

At the tip, the drill features a precision-ground 135° split point. This advanced geometry allows the bit to self-center immediately upon contact with the workpiece, preventing the common issue of "walking" across the surface. This feature removes the need for pre-drilling or center punching, streamlining your workflow and ensuring accurate hole placement every time. It is particularly effective on round surfaces and thin-walled materials where precision is critical.

The bit is finished with Walter's exclusive bronze SST surface treatment. This specialized coating significantly reduces friction between the tool and the material, promoting efficient chip evacuation and minimizing heat buildup. The result is a drill bit that maintains its cutting edge longer, even when drilling through tough materials like stainless steel, mild steel, and non-ferrous alloys. Whether used in stationary machinery or portable hand drills, the Walter SST Stub Drill delivers consistent, high-quality performance.
