Walter SST+ 23/32" Cobalt Prentice Drill Bit with 1/2" Shank

Drill Big Holes in Tough Metal with Confidence

When you are out in the field or working in the shop, needing to drill a large hole in stainless steel can be a headache—especially if you only have a standard 1/2-inch drill. The Walter 23/32" SST+ Prentice Drill Bit solves this problem instantly. Known in the industry as a "Prentice" or reduced-shank bit, it gives you the cutting power of a large industrial bit while fitting securely into your standard 1/2-inch drill chuck. This means you don't need to haul around heavy machinery or specialized tool holders just to drill a 23/32" hole.

Built for Stainless Steel and Hard Alloys

Standard drill bits often burn out the moment they touch stainless steel. The Walter SST+ is different. It is crafted with a special Cobalt blend that allows the bit to withstand the intense heat generated when drilling hard metals. This heat resistance keeps the cutting edges sharp far longer than standard high-speed steel bits. Additionally, the unique bronze SST surface treatment acts as a lubricant, helping chips slide out of the hole easily and preventing the bit from binding up. This results in faster cuts, cooler operation, and a much longer life for your tool investment.

No More Slipping or Walking

We have all experienced the frustration of a drill bit spinning inside the chuck when the going gets tough. The Walter 01M546 eliminates this annoyance with its 3-flat shank design. These flat surfaces lock into your drill's jaws, guaranteeing that the bit turns when the drill turns, no matter how much torque is applied. On the business end, the bit features an aggressive, self-centering point. You can say goodbye to "walking" bits that scratch up your workpiece; this bit bites into the metal immediately, allowing you to drill accurate holes without needing to pre-drill a pilot hole.

Ideal for Professional Welders and Fabricators

Whether you are fabricating structural steel, repairing heavy equipment, or working on custom stainless projects, this bit is a workhorse. It is designed to handle:

• Stainless Steel
• Mild Steel
• Aluminum and Non-Ferrous Metals
• Round stock and pipe

Upgrade your toolbox with the Walter SST+ Prentice drill and experience the difference that premium geometry and materials make on your toughest jobs.
