01R232 - Walter SST+ 1/2-Inch Drill Bit with 3/8-Inch Reduced Shank

High-Performance Drilling for Tough Materials

The Walter 01R232 SST+ Drill Bit is an essential tool for industrial professionals who require precision and durability when drilling through tough metals. This specific bit features a 1/2-inch cutting diameter but is engineered with a 3/8-inch reduced shank. This unique design allows fabricators and maintenance personnel to drill larger holes using standard portable power drills that may only have a 3/8-inch chuck capacity. By bridging the gap between heavy-duty drilling requirements and standard tool capacities, this bit offers unmatched versatility in the field.

At the core of this drill bit is Walter's proprietary SST+ material technology. Manufactured from a premium cobalt blend, the bit is designed to withstand the high temperatures generated when drilling hard materials like stainless steel. Unlike standard high-speed steel (HSS) bits that can dull quickly under thermal stress, the SST+ composition maintains its hardness, ensuring a longer service life and more holes per bit. This makes it a cost-effective choice for high-volume workshops where downtime for tool changes needs to be minimized.

Precision is paramount with the 01R232. It features a 135° self-centering split point geometry. This aggressive point angle allows the bit to bite into the material immediately upon contact, effectively eliminating the "walking" or skating often experienced with standard 118° points. This means users can drill accurate holes without the need for pre-punching or pilot holes, saving time and effort. The heavy-duty web construction further enhances the bit's rigidity, reducing the risk of snapping when breaking through the other side of the workpiece.

Whether you are working with mild steel, non-ferrous metals, or challenging stainless steel alloys, the Walter SST+ reduced shank bit delivers consistent, professional results. Its efficient flute design aids in rapid chip evacuation, keeping the cutting edge cool and preventing work-hardening of the material. For MRO operations and custom fabrication, this tool is a reliable problem solver.
