01M600 - Walter 1-Inch SST+ Cobalt Prentice Drill Bit with 1/2-Inch Shank

Precision Drilling for Fabricators

Upgrade your metalworking capabilities with the Walter 1" SST+ Prentice Drill Bit, a tool built to handle the rigorous demands of professional welding and fabrication shops. When you need to drill large holes but only have access to a standard 1/2-inch chuck, this bit provides the perfect solution. The 1-inch cutting diameter is seamlessly integrated with a reduced 1/2-inch shank, making it compatible with a wide range of equipment, from portable hand drills to stationary drill presses. This compatibility ensures you can achieve large-bore holes without investing in specialized heavy machinery.

Drilling through stainless steel and other hard metals requires a bit that can withstand intense heat and abrasion. The Walter 01M600 is crafted from a superior cobalt blend that resists thermal breakdown, maintaining a sharp cutting edge far longer than conventional bits. This durability translates to cleaner cuts, fewer burrs, and a lower cost per hole over the life of the tool. The addition of a bronze SST surface treatment adds a layer of lubricity, helping to shed chips and reduce friction, which is essential for maintaining drilling speed and accuracy.

One of the most practical features for the daily user is the "Secure-Grip" shank design. The 1/2-inch shank is ground with three flats, which align perfectly with the jaws of your drill chuck. This prevents the annoying and damaging slippage often encountered when driving large bits through thick plate. Furthermore, the high-performance point geometry allows you to start drilling exactly where you need to, without the bit wandering across the workpiece. By eliminating the need for pre-drilling pilot holes, this Walter SST+ bit saves you time and effort on every job.
