The Walter 01H128 7\/16″ SST Stub Drill is an industrial-grade cutting tool engineered for precision and durability in demanding metalworking environments. Distinguished by its “stub” or screw machine length, this drill bit offers significantly higher rigidity compared to standard jobber length bits. This increased stiffness minimizes deflection and vibration, resulting in cleaner, more accurate holes and a drastically reduced risk of breakage, even under heavy feed pressure.<\/p>\n
Manufactured with Walter’s proprietary SST (Super Speed Treatment) bronze surface finish, this bit is designed to withstand high thermal loads. The specialized coating facilitates efficient chip evacuation and reduces friction, preventing the work-hardening often encountered when drilling stainless steel and other tough alloys. The tool features a sophisticated 135\u00b0 split point geometry that is self-centering, allowing operators to begin drilling immediately upon contact without the need for pre-punching or pilot holes. This feature is particularly advantageous when working on curved surfaces or thin-walled tubing where bit wandering is a common issue.<\/p>\n
Ideally suited for MRO operations, fabrication shops, and automotive manufacturing, the 01H128 excels in drilling sheet metal, mild steel, and non-ferrous metals. Its compact form factor makes it the tool of choice for applications with limited clearance, such as inside electrical cabinets, vehicle frames, or complex machinery assemblies. By combining a heavy-duty web construction with advanced geometry, Walter Surface Technologies delivers a drilling solution that maximizes productivity and tool life.<\/p>\n","protected":false},"excerpt":{"rendered":"High-Performance Drilling for Confined Spaces The Walter 01H128 7\/16″ SST Stub Drill is an industrial-grade cutting tool engineered for precision and durability in demanding metalworking environments.
