01H122 - 11/32 Inch Hex Shank SST Stub Drill Bit for Sheet Metal

High-Performance Drilling for Sheet Metal and Thin Materials

The Walter 01H122 11/32" Hex SST Stub Drill is engineered for professionals who demand precision and durability in their drilling operations. Designed specifically for sheet metal and thin-walled materials, this drill bit solves common frustrations associated with standard length bits, such as wandering and breakage. The "stub" length design significantly increases the rigidity of the bit, allowing for higher feed pressure without the risk of snapping, making it an essential tool for high-volume fabrication environments.

One of the standout features of this drill is its 135° split point geometry. Unlike standard 118° points that require a center punch to start, the Walter SST split point bites into the material immediately upon contact. This self-centering capability is particularly valuable when working on curved surfaces or round stock, where standard bits tend to "walk" and mar the finish. The elimination of pre-punching steps translates directly to increased productivity and faster cycle times.

To further enhance performance, Walter has applied a special bronze SST surface treatment. This advanced coating reduces friction between the bit and the workpiece, effectively dissipating heat and preventing the work-hardening of sensitive materials like stainless steel. Combined with a hex shank that ensures a positive, non-slip drive in any standard or quick-change chuck, this tool delivers consistent, burr-free holes with minimal effort. Whether you are drilling mild steel, non-ferrous metals, or stainless steel, the Walter SST Stub Drill is the reliable choice for tight spaces and tough jobs.
