01H126 - Walter 13/32 Inch SST+ Hex Shank Stub Drill Bit for Sheet Metal

Precision Engineering for Industrial Drilling Applications

The Walter 01H126 13/32" Hex SST Stub Drill represents the pinnacle of drilling efficiency for maintenance, repair, and operations (MRO) professionals. Engineered specifically for high-torque applications and challenging materials, this drill bit addresses the common failure points associated with standard jobber-length bits. The defining characteristic of this tool is its "stub" or screw machine length. By significantly reducing the overall length and flute length, Walter has created a drill bit with exceptional torsional rigidity. This structural stiffness minimizes deflection under load, drastically reducing the likelihood of breakage, even when high feed pressure is applied in manual drilling operations.

Beyond its robust geometry, the 01H126 features Walter's proprietary Bronze SST surface treatment. This specialized coating is not merely aesthetic; it serves a critical tribological function by reducing the coefficient of friction between the tool and the workpiece. Lower friction translates to reduced heat generation—the primary enemy of cutting tool life—allowing the bit to maintain its hardness and cutting edge integrity for longer periods, particularly when drilling abrasive or work-hardening materials like stainless steel.

The cutting geometry is equally advanced, boasting a 135° split point. Unlike standard 118° chisel points that require a center punch to prevent wandering, the 135° split point begins cutting immediately upon contact. This self-centering capability is indispensable when working with sheet metal or curved surfaces, ensuring precise hole placement every time. Furthermore, the integration of a hex shank allows for compatibility with a wide array of power tools, including impact drivers and quick-change chucks, ensuring a positive drive without slippage. For industrial environments where time is money and tool failure causes costly downtime, the Walter SST Stub Drill offers a reliable, high-performance solution.

This tool is specifically optimized for drilling through thin-walled materials and sheet metal, where control and speed are paramount. The shorter flute length allows for rapid chip evacuation in shallow holes, preventing clogging and binding. Whether utilized in stationary drill presses or portable power tools, the Walter 01H126 delivers consistent, burr-free results, making it an essential component of any professional industrial tooling inventory.
