01R226 - Walter SST+ 13/32" Cobalt Drill Bit with 3/8" Reduced Shank

High-Performance Drilling for Tough Alloys

The Walter 01R226 SST+ 13/32" Drill Bit is engineered for the professional fabricator who demands precision and durability. Part of Walter's renowned SST+ series, this drill bit is formulated with a premium cobalt blend High Speed Steel (HSS), making it exceptionally resistant to the high heat generated when drilling tensile materials like stainless steel. Unlike standard bits that dull quickly, the SST+ maintains its cutting edge longer, ensuring consistent performance across multiple holes.

One of the standout features of this specific SKU is its 3/8" reduced shank. This design allows users to drill a 13/32" hole using a drill with a maximum chuck capacity of 3/8", expanding the versatility of standard portable power tools. The bit features a 135° self-centering split point, which bites into the metal immediately upon contact. This eliminates the common issue of "walking" or wandering across the workpiece, removing the need for pre-punching and ensuring precise hole placement even on round surfaces like pipes or tubing.

The heavy-duty web construction adds rigidity to the bit, preventing snapping under the torque required for larger diameter drilling. Combined with a bronze oxide finish that aids in chip flow and friction reduction, the Walter 01R226 is the ideal choice for MRO applications, heavy fabrication, and any task requiring reliable drilling in mild steel, non-ferrous metals, and stainless steel.
