OVERVIEW

High-Performance Industrial Drilling Solution

The Walter 01M534 17/32" SST+ Prentice Drill Bit represents the pinnacle of heavy-duty drilling technology for industrial maintenance and fabrication environments. Engineered by Walter Surface Technologies, this tool is specifically designed to overcome the common failure points associated with drilling large diameter holes in tough materials. At the core of its performance is a proprietary cobalt blend High Speed Steel (HSS) substrate. Unlike standard black oxide bits, this cobalt-infused material maintains its hardness at significantly higher temperatures, making it the ideal choice for drilling stainless steel, structural steel, and other hard ferrous alloys where heat generation is a critical factor.

One of the standout features of the SST+ Prentice line is the intelligent shank design. While the cutting diameter is 17/32 of an inch, the bit features a reduced 1/2-inch shank, allowing it to be used in standard 1/2-inch chucks found on portable power drills, magnetic drills, and drill presses. Crucially, this shank is machined with three distinct flats. This "Secure-Grip" design mechanically locks into the chuck jaws, effectively eliminating the frustration of the bit spinning inside the chuck under high-torque loads—a common issue when drilling large holes in thick plate.

Efficiency is further enhanced by Walter's exclusive point geometry. The bit is designed to be self-centering, which prevents "walking" upon initial contact with the workpiece. This precision allows operators to drill accurate holes without the time-consuming step of center punching or using smaller pilot bits. The Bronze SST surface treatment acts as a lubricant and heat shield, reducing friction during the cut and promoting smooth chip evacuation. For MRO professionals seeking a reliable, long-lasting solution for large-diameter drilling tasks, the 01M534 offers a perfect balance of durability, precision, and ease of use.

FAQ

The cutting diameter is 17/32 of an inch, which is slightly larger than 1/2 inch.

Yes, this is a Prentice-style bit with a reduced shank turned down to 1/2 inch, specifically designed to fit standard 1/2 inch chucks.

Absolutely. The SST+ series is made from a cobalt blend HSS which is specifically engineered to withstand the heat and hardness of stainless steel.

In most cases, no. The bit features an exclusive self-centering point geometry that prevents walking and allows for drilling without a pilot hole.

The three flats allow the jaws of the drill chuck to grip the bit securely, preventing it from spinning inside the chuck under high torque.

It is a specialized coating that improves heat resistance, reduces friction during drilling, and helps with chip flow to extend tool life.

Yes, provided the magnetic drill is equipped with a standard 1/2" capacity 3-jaw chuck or an adapter for straight shank bits.
