01M561 - Walter SST+ 61/64-Inch Prentice Drill Bit with 1/2-Inch Shank

Drill Large Holes with Ease and Precision

Upgrade your drilling capabilities with the Walter SST+ 61/64" Prentice Drill Bit, a top-tier solution for welders and fabricators working with hard metals. If you need to drill large holes but only have a standard 1/2-inch chuck drill, this is the perfect tool for the job. The "Prentice" style design features a reduced shank that fits into standard 1/2-inch chucks, allowing you to bore 61/64-inch holes without needing specialized heavy machinery. It is an essential addition to any toolbox for on-site repairs or shop fabrication where versatility is key.

One of the biggest frustrations in drilling is bit slippage. Walter solves this with a smartly designed shank featuring three flat sides that lock securely into your drill's chuck. This "Sure-Grip" design ensures maximum torque transfer, so the bit turns through the metal, not inside your drill. The bit itself is crafted from a durable cobalt blend, specifically formulated to cut through tough stainless steel and other hard alloys that would dull ordinary bits in seconds. The bronze SST surface treatment further aids in keeping the bit cool and clearing debris, extending the life of your investment.

Forget about walking bits and pilot holes. The Walter SST+ features a high-performance self-centering tip that bites into the metal instantly. This means you can start drilling exactly where you marked, even on round surfaces like pipes or tubing. Whether you are drilling through structural steel, aluminum, or stainless plate, this bit provides the aggressive cutting action and longevity you need to get the job done right the first time.
