01M608 - Walter SST+ 1-1/8 Inch Reduced Shank Drill Bit for Stainless Steel

Heavy-Duty 1-1/8" Drill Bit for Stainless & Steel

For welders and fabricators, time is money, and struggling to drill large holes in the field is a major productivity killer. The Walter 1-1/8" SST+ Prentice Drill (01M608) is the ultimate problem solver for your tool crib. Whether you are modifying a truck frame, installing piping, or fabricating structural steel, this bit gives you the power to drill massive 1-1/8 inch holes using your standard hand-held 1/2-inch drill or mag drill. No need to haul the workpiece to a machine shop; bring the capacity to the job site.

Drilling stainless steel requires a bit that can take the heat, and the SST+ series delivers. Infused with a cobalt blend, this drill bit resists the thermal breakdown that ruins ordinary HSS bits. It cuts faster, stays cooler, and lasts significantly longer, meaning you spend less time swapping dull bits and more time fabricating. The heavy-duty web construction adds rigidity, preventing the snapping and breakage often seen when applying the heavy feed pressure needed for large holes.

One of the biggest frustrations with large reduced-shank bits is slippage in the chuck. When a bit spins, it chews up the shank and ruins your drill chuck jaws. Walter solves this with a secure 3-flat shank design that guarantees a non-slip grip, delivering 100% of your drill's torque to the cutting edge. Additionally, the precision 135-degree split point allows you to start drilling exactly where you marked, without the bit wandering across the surface. This feature also eliminates the extra step of drilling a pilot hole, speeding up your workflow. From aluminum to hardened stainless, the Walter 01M608 is the reliable, high-performance choice for serious metalworkers.
