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

Walter SST+ 25/64" Reduced Shank Drill Bit

Upgrade your drilling arsenal with the Walter 01R225 SST+ Drill Bit, a premium solution for welders and fabricators who demand precision and durability. If you have ever needed to drill a hole slightly larger than 3/8" but were limited by the chuck size of your hand drill, this tool is the answer. The 01R225 features a 25/64-inch cutting diameter but is machined with a reduced 3/8-inch shank, allowing it to fit securely into standard 3/8-inch chucks found on most cordless and corded power drills. This smart design eliminates the need to upgrade to a bulky 1/2-inch drill for mid-sized holes, saving you time and money in the shop.

Drilling through tough metals like stainless steel can be a nightmare with inferior bits, often resulting in work-hardening the material or burning out the bit. The Walter SST+ series is formulated with a high-performance cobalt-blend HSS that thrives in high-heat applications. The 135-degree split point is a game-changer for accuracy; it centers itself the moment it touches the metal, preventing the bit from wandering and damaging the finish of your workpiece. This is especially critical when drilling on round stock or in tight positions where using a center punch isn't feasible. The aggressive cutting action requires less force from the user, reducing fatigue during repetitive drilling tasks.

Whether you are fabricating custom brackets, repairing equipment, or working on automotive projects, the Walter 01R225 delivers clean, round holes with minimal burring. The flute geometry is optimized to eject chips quickly, preventing clogging and overheating. This bit is not just for steel; it performs exceptionally well on aluminum and other non-ferrous metals, making it a versatile addition to any welder's toolbox. Invest in professional-grade tooling that lasts longer and cuts faster, ensuring your projects are completed with the quality and speed you expect.
