The Walter 01H032 1\/2″ SST Stub Drill is an industrial-grade cutting tool engineered specifically for demanding drilling applications where rigidity and precision are paramount. Unlike standard jobber-length bits, this stub drill (often referred to as screw machine length) features a shorter flute and overall length. This compact design significantly reduces the torsional flex that often leads to bit breakage, making it an exceptional choice for drilling through tough materials like stainless steel and mild steel, particularly in high-torque scenarios.<\/p>\n
At the core of its performance is the 135\u00b0 split point geometry. This advanced tip design allows the drill to self-center immediately upon contact with the workpiece, effectively eliminating the “walking” phenomenon common with standard 118\u00b0 points. This feature removes the necessity for pre-drilling or center punching, thereby streamlining workflow and increasing productivity in high-volume fabrication environments. The split point also reduces the thrust load required to penetrate the material, which preserves the life of both the tool and the drilling machinery.<\/p>\n
The bit is treated with Walter\u2019s proprietary Bronze SST surface treatment. This specialized coating serves a dual purpose: it enhances the hardness of the bit’s surface and significantly reduces the coefficient of friction during operation. By minimizing friction, heat generation is kept in check\u2014a critical factor when drilling work-hardening alloys like stainless steel. The result is a cleaner cut, reduced burr formation, and a substantially longer tool life compared to untreated high-speed steel bits. Whether utilized in stationary drill presses or portable hand drills, the 01H032 delivers consistent, professional results in thin-walled materials and sheet metal.<\/p>\n","protected":false},"excerpt":{"rendered":"High-Performance Rigidity for Precision Drilling The Walter 01H032 1\/2″ SST Stub Drill is an industrial-grade cutting tool engineered specifically for demanding drilling applications where rigidity and precision are paramount.
