01H113 - Walter 13/64 Inch Hex Shank Stub Drill Bit for Sheet Metal

Heavy-Duty Drilling Performance with Walter SST Stub Drills

When precision and durability are non-negotiable in your workshop or job site, the Walter 13/64" Hex SST Stub Drill (SKU: 01H113) stands out as a premier choice for professionals. Designed specifically to tackle the challenges of drilling into thin-walled materials and tough alloys, this drill bit combines advanced geometry with high-quality materials. The "Stub" or screw machine length offers significantly higher rigidity compared to standard jobber length bits. This increased stiffness drastically reduces the risk of breakage, especially when applying side pressure or working in confined spaces where tool control is critical.

The 01H113 features a specialized 135° split point. Unlike standard 118° points that often wander before biting into the metal, this split point self-centers immediately upon contact. This feature eliminates the need for pre-drilling or center punching, saving you valuable time on every hole. It is particularly effective on curved surfaces, such as pipes or tubing, where standard bits tend to slip. Whether you are working with mild steel, aluminum, or more demanding stainless steel sheets, this drill bit delivers clean, round holes with minimal burr formation.

One of the defining features of this tool is its 1/4" Hex shank. This design allows for compatibility with quick-change adapters and impact drivers, ensuring a positive drive without slippage in the chuck. The bit is treated with Walter's exclusive bronze SST surface finish, which helps dissipate heat and reduce friction during high-speed drilling. This thermal management extends the life of the cutting edge, making it a cost-effective solution for high-volume fabrication shops. At Josef Gas, we recommend this bit for anyone performing bodywork, HVAC installation, or general sheet metal fabrication.

Key Benefits:

• Enhanced Durability: Short flute design resists snapping under torque.
• Precision Starts: Self-centering point prevents walking on smooth surfaces.
• Versatile Compatibility: Hex shank fits standard chucks and impact drivers.
• Heat Resistance: Bronze treatment prolongs tool life in tough metals.
