01R225 - Walter SST+ 25/64" Drill Bit, 3/8" Reduced Shank, Cobalt Blend HSS

Industrial Grade Walter SST+ Drill Bit 25/64"

The Walter 01R225 SST+ Drill Bit represents the pinnacle of drilling technology for industrial maintenance and fabrication environments. Designed specifically to bridge the gap between heavy-duty capacity and standard tooling, this bit features a precision-engineered 25/64-inch cutting diameter coupled with a reduced 3/8-inch shank. This configuration allows operators to drill holes larger than their chuck capacity would typically permit, making it an indispensable tool for facilities utilizing standard 3/8-inch portable drills or drill presses. The bit is manufactured from Walter's proprietary SST+ high-speed steel formula, which likely incorporates a cobalt blend to withstand the high temperatures generated when drilling tough alloys.

In high-throughput industrial settings, efficiency and tool life are paramount. The 01R225 is built with a 135-degree self-centering split point. This geometry eliminates the need for center punching or pilot holes, as the bit bites into the material immediately upon contact without "walking" or skating across the surface. This feature is particularly valuable when working on curved surfaces such as pipes or tubing. The specialized helix design ensures rapid chip evacuation, pulling debris away from the cutting edge to reduce friction and heat buildup. By maintaining a cooler cutting temperature, the temper of the bit is preserved longer, resulting in a significantly extended service life compared to standard black oxide or general-purpose bits.

This drill bit is engineered for versatility across a wide range of materials commonly found in MRO applications, including mild steel, stainless steel, and various non-ferrous metals. Its robust web construction provides added strength to resist torsional stress, reducing the likelihood of breakage under heavy load. For procurement managers and tool crib supervisors, stocking the Walter SST+ reduced shank series ensures that maintenance teams have the capability to perform large-diameter drilling tasks without requiring specialized heavy-duty drilling machinery.
