01H132 - Walter 1/2 Inch SST Stub Drill Bit with Hex Shank

Industrial-Grade Precision with Walter SST Stub Drills

The Walter 01H132 1/2" Hex SST Stub Drill is engineered for the demanding requirements of industrial maintenance, repair, and operations (MRO). Designed with a focus on durability and precision, this drill bit represents a significant upgrade over standard jobber-length bits, particularly when working with thin-walled materials or in confined spaces. The "stub" or screw machine length configuration offers superior rigidity, drastically reducing the flex that often leads to breakage in longer bits. This structural integrity allows operators to apply the necessary feed pressure to cut through tough alloys without the risk of snapping the tool, ensuring a lower cost per hole and reduced downtime on the shop floor.

At the core of this tool's performance is its 135° split point geometry. Unlike standard 118° points that require a center punch to prevent wandering, the Walter SST split point bites into the material immediately upon contact. This self-centering feature is critical for maintaining hole location accuracy, especially on slick or curved surfaces like pipes and sheet metal. The specialized bronze SST surface treatment further enhances the bit's capabilities by reducing friction and facilitating efficient chip evacuation. This treatment acts as a thermal barrier, dissipating heat away from the cutting edge to prolong tool life even when drilling through work-hardening materials like stainless steel.

Efficiency is paramount in industrial settings, and the 01H132 delivers with its hex shank design. This feature eliminates the common frustration of round shanks spinning inside the drill chuck under high torque loads. It ensures positive power transmission and allows for rapid tool changes, making it compatible with a wide range of power tools, including impact drivers. Whether utilized in stationary drill presses or portable hand drills, the Walter SST Stub Drill provides consistent, burr-free performance. It is an essential component for any professional toolkit, offering the reliability needed to tackle mild steel, non-ferrous metals, and stainless steel with confidence and speed.
