01R230 - Walter SST+ 15/32" Drill Bit with 3/8" Reduced Shank

Precision Drilling with Walter SST+ Technology

The Walter 01R230 15/32" SST+ Drill Bit is engineered for professionals who demand accuracy and durability in their metalworking tools. Part of the renowned SST+ series, this drill bit is specifically designed to tackle tough materials like stainless steel and mild steel with ease. Its standout feature is the 3/8" reduced shank, which ingeniously allows operators to drill holes larger than their chuck capacity—specifically enabling a 15/32" diameter hole using a standard 3/8" drill chuck. This versatility makes it an essential addition to any tool kit, bridging the gap between portable drill limitations and heavy-duty drilling requirements.

Performance is at the core of the SST+ design. The bit features a 135° self-centering split point geometry. Unlike standard 118° points that often wander upon contact, this split point bites into the material immediately, preventing "walking" and eliminating the need for pre-punching a center hole. This results in faster penetration rates and significantly reduced operator fatigue, as less downward pressure is required to maintain the cut. Whether you are drilling into flat plate, round tubing, or irregular surfaces, the stability provided by this geometry ensures a clean, precise hole every time.

Durability is paramount in industrial environments, and Walter delivers with a high-performance alloy construction capable of withstanding the heat and stress of drilling hard metals. The flute design efficiently evacuates chips, reducing heat buildup that can dull lesser bits. Ideal for maintenance, repair, and fabrication tasks, the Walter 01R230 excels in drilling non-ferrous metals, mild steel, and particularly stainless steel, where work-hardening can be a challenge for inferior bits. Trust in Walter's abrasive and cutting expertise to provide a drill bit that stays sharp longer and performs consistently under pressure.
