01H022 - Walter 11/32 Inch SST Heavy Duty Stub Drill Bit

Heavy-Duty Precision for Industrial Drilling

The Walter 11/32" SST Stub Drill (01H022) is a premium cutting tool designed to meet the rigorous demands of industrial maintenance, repair, and fabrication. Engineered by Walter Surface Technologies, this drill bit distinguishes itself with a robust "stub" or screw machine length design. Unlike standard jobber length bits, the shorter profile of the SST Stub Drill offers significantly enhanced rigidity. This structural stability minimizes the flexing and vibration that often lead to tool breakage, particularly when drilling into hard materials like stainless steel or when applying heavy feed pressure.

Efficiency in metalworking is defined by speed and accuracy. The Walter 01H022 features a sophisticated 135° split point geometry. This self-centering design allows the drill to bite into the material immediately upon contact, eliminating the time-consuming step of center punching. It effectively prevents "walking" or wandering across the workpiece, which is critical when drilling into curved surfaces or expensive finished metals where surface marring is unacceptable. The specialized bronze SST surface treatment further enhances performance by reducing friction and facilitating smooth chip evacuation, thereby keeping the cutting edge cooler and extending the tool's service life.

This drill bit is particularly effective for drilling through thin-walled materials and sheet metal, where standard bits might tear the material or produce out-of-round holes. Its capability to produce clean, burr-free holes makes it an essential asset for workshops handling mild steel, non-ferrous metals, and stainless steel alloys. Whether used in stationary drill presses or portable hand drills, the Walter SST Stub Drill delivers consistent, professional results.

Key Industrial Benefits

• Breakage Resistance: Short flute length withstands higher torque and side pressure.
• Material Versatility: Excellent performance on stainless steel, mild steel, and aluminum.
• Precision Starting: 135° point ensures accuracy without pilot holes.
