Walter SST+ Multi-Step Drill Bit Set - 3 Piece AlCrN Coated

The Fabricator's Choice for Clean Holes

When you are out in the shop or on a job site, you need tools that multitask as well as you do. The Walter 01W951 Multi-Step Drill Set is the ultimate problem solver for welders and fabricators working with sheet metal and thin-walled tubing. Forget about carrying a heavy index box full of twist drills that snag and tear thin materials. This three-piece set gives you the capability to drill dozens of different hole sizes with just three tools, allowing you to move faster and work cleaner.

Drilling stainless steel sheet metal is notoriously difficult due to work hardening, but Walter has engineered these bits to cut freely and stay cool. The secret is in the AlCrN coating and the specialized flute design. As you drill, the bit creates its own pilot hole and progressively enlarges it to your desired diameter, deburring the edge as it goes. This means you get a perfectly round, clean hole in one pass, ready for a bolt or conduit connector. The two-flute design helps clear the metal shavings quickly, so you can see your markings and keep the heat down.

We know that nothing is more frustrating than a drill bit spinning inside your chuck when you are halfway through a cut. Walter solved this by machining three flat surfaces onto the shank of every bit in this set. Whether you are using a cordless drill or a drill press, these bits lock in tight and transfer all the power to the cutting edge. From installing gauges on a control panel to modifying a stainless steel backsplash, this set covers the most common sizes you will encounter: 1/8" to 1/2", 3/16" to 7/8", and 1/4" to 1-3/8".
