01M616 - Walter SST+ Prentice Drill Bit 1-1/4 Inch Cobalt Blend

Heavy-Duty 1-1/4" Drill Bit for Stainless & Steel

When you are out in the shop or on a job site, you need tools that can handle the pressure. The Walter 1-1/4" SST+ Prentice Drill Bit (01M616) is built for welders and fabricators who need to drill big holes without dragging out heavy stationary machinery. This bit features a "Prentice" style reduced shank, meaning you can drive a massive 1-1/4 inch cutter using your standard 1/2-inch hand drill or mag drill. It is the ultimate problem solver for field fabrication where equipment options are limited but performance requirements are high.

Drilling through stainless steel is notorious for burning up standard bits, but the Walter SST+ is up to the challenge. It is crafted with a special cobalt blend that resists the intense heat generated by drilling hard metals. This means the cutting edges stay sharp longer, allowing you to drill more holes per bit before you even have to think about resharpening. The bronze surface treatment adds another layer of protection, helping chips slide out of the hole easily and keeping the bit cooler during operation. This durability translates directly to cost savings and less downtime for your crew.

Slippage is a major annoyance when drilling large holes, often damaging the bit shank or the drill chuck. Walter has solved this with a 3-flat shank design that guarantees a secure grip in the chuck jaws. You get 100% of the drill's power transferred to the cutting edge. Additionally, the exclusive point geometry is designed to start drilling on contact. You won't need to waste time drilling pilot holes or worrying about the bit wandering across the surface. For reliable, heavy-duty drilling in mild steel, stainless, and aluminum, the Walter 01M616 is the professional's choice.
