01H116 - Walter SST+ 1/4 Inch Stub Drill Bit with Hex Shank

Industrial Grade Short Length Drilling Solution

The Walter 01H116 1/4" Hex SST Stub Drill is a specialized cutting tool designed to address the common challenges faced by maintenance, repair, and operations (MRO) professionals when working with thin-walled materials and in confined spaces. Unlike standard jobber-length drills, this stub drill features a significantly shorter overall length and flute length. This compact geometry drastically reduces the moment arm, providing exceptional rigidity and virtually eliminating the risk of breakage due to flexing or lateral pressure. This makes it an indispensable tool for high-torque applications and situations where the drill cannot be held perfectly perpendicular to the workpiece.

Engineered with productivity in mind, this bit features a 1/4" quick-change hex shank. This shank design allows for seamless compatibility with modern impact drivers and quick-release chucks, enabling operators to switch between drilling pilot holes and driving fasteners in seconds without changing tools. The positive engagement of the hex shank also prevents the bit from slipping in the chuck, a common issue with round-shank drills under heavy load. The drill is manufactured from premium High-Speed Steel (HSS) and undergoes Walter's proprietary bronze SST surface treatment. This treatment increases surface hardness and lubricity, effectively reducing heat generation and chip welding, which are the primary causes of premature tool failure in stainless steel and aluminum.

Precision is paramount in sheet metal fabrication, and the 01H116 delivers with its 135° split point geometry. This advanced point design creates a self-centering action that bites into the material immediately upon contact. It eliminates the phenomenon of "walking" or wandering across the surface, thereby removing the need for pre-drilling center punches. This feature not only saves time but also ensures hole accuracy and prevents cosmetic damage to the workpiece. Whether used in stationary machinery or portable power tools, this drill bit offers a superior balance of durability, speed, and precision for demanding industrial environments.
