01J010 - Walter SST Cobalt Stub Drill Bit #10 - Heavy Duty Sheet Metal Bit

The Toughest Bit for the Toughest Metals

Every welder knows the frustration of snapping a drill bit halfway through a job, especially when working with stubborn materials like stainless steel or trying to drill out a spot weld. The Walter #10 SST Stub Drill Bit is the solution to that frustration. Designed with a "stub" or screw machine length, this bit is shorter and stockier than your average drill bit. This compact design gives it incredible strength, making it virtually unbreakable under normal drilling conditions. It won't flex or bend when you lean into it, giving you the confidence to drill through heavy-gauge sheet metal without snapping the tool.

When you are out in the field or on the shop floor, you need a bit that starts cutting the second it touches the metal. The 135-degree split point on this Walter bit does exactly that. It self-centers immediately, so you don't have to waste time hunting for a center punch or worrying about scratching up a finished surface because the bit wandered off the mark. This feature is a lifesaver when drilling overhead or in awkward positions where applying steady pressure is difficult.

The secret to its performance lies in the cobalt blend material. Standard bits burn up quickly when drilling stainless steel because the metal work-hardens and generates intense heat. The cobalt in this Walter bit resists that heat, keeping the cutting edge sharp hole after hole. Combined with the slick Bronze SST coating that helps clear chips out of the way, this bit runs cooler and cuts faster. Whether you are installing rivets, drilling pilot holes, or fabricating custom brackets, the Walter 01J010 is the reliable workhorse you need in your toolbox.
