01H004 - Walter 01H004 1/16-Inch SST Stub Drill Bit, 135-Degree Split Point

Precision Drilling for Industrial Fabrication

The Walter 01H004 1/16" SST Stub Drill is a premium cutting tool engineered for professionals who demand reliability and precision in their metalworking operations. Designed specifically for the challenges of drilling into thin-walled materials and tough alloys, this drill bit stands out as a robust solution for sheet metal fabrication. The "stub" length configuration—significantly shorter than standard jobber drills—provides exceptional rigidity. This structural stiffness is critical when working with small diameters like 1/16", as it drastically reduces the flex and vibration that typically lead to bit breakage. For industrial workshops where downtime equates to lost revenue, the durability of the Walter SST line ensures continuous productivity.

Advanced Geometry for Stainless Steel

Drilling into stainless steel requires a tool that can withstand high heat and abrasive wear. The Walter 01H004 features a specialized bronze SST surface treatment that facilitates chip evacuation and reduces friction, thereby extending the life of the cutting edge. The 135-degree split point geometry is a standout feature, allowing the drill to bite into the material immediately upon contact. This self-centering capability eliminates the phenomenon known as "walking," where a bit skids across the surface before penetrating. Consequently, users can bypass the time-consuming step of center punching, making this tool highly efficient for high-volume drilling tasks.

Optimized for Tight Spaces

Beyond its cutting capabilities, the physical dimensions of this stub drill make it an indispensable asset for complex assemblies. Its compact length allows it to fit into confined spaces where a standard drill bit would be too long to maneuver. Whether you are drilling out rivets, creating pilot holes in automotive bodywork, or fabricating HVAC components, the Walter 01H004 delivers the clearance you need without sacrificing performance. It produces clean, round holes with minimal burr formation, reducing the need for secondary deburring operations and ensuring a high-quality finish on every project.
