01R240 - Walter SST+ 5/8 Inch Drill Bit with 3/8 Inch Reduced Shank

High-Performance 5/8" Drilling with Standard Chucks

The Walter 01R240 SST+ Drill Bit is engineered for professionals who require precision and durability when drilling large diameter holes using portable power tools. This specific bit features a 5/8-inch cutting diameter turned down to a 3/8-inch reduced shank, allowing it to fit securely into standard 3/8-inch drill chucks. This design eliminates the need for heavy-duty 1/2-inch drills for mid-sized holes, providing versatility on the job site.

Advanced SST+ Geometry

Part of Walter's renowned SST+ series, this drill bit is manufactured from a high-quality cobalt blend high-speed steel (HSS). This material composition offers exceptional heat resistance, significantly extending the tool's life even when drilling through tough materials like stainless steel and hard alloys. The bit features a 135° self-centering split point, which bites into the metal immediately upon contact. This prevents the bit from "walking" or wandering across the surface, ensuring precise hole placement without the need for a center punch—even on curved surfaces like pipes and tubing.

Optimized for Tough Materials

The 01R240 is designed to handle a wide range of materials, including mild steel, stainless steel, and non-ferrous metals. Its heavy-duty helix design efficiently evacuates chips, reducing heat buildup and preventing binding. The bronze oxide finish further aids in lubricity and wear resistance. Whether you are working in maintenance, fabrication, or installation, this reduced shank bit provides the torque transmission and cutting efficiency required for professional results.

Key Technical Benefits

• Compatibility: Fits 3/8" chucks while drilling 5/8" holes.
