Walter SST+ 7/64 Inch Cobalt Drill Bit for Stainless Steel

Tough Bits for Tough Metals: Walter SST+ 7/64"

Every welder knows the frustration of a dull drill bit, especially when trying to prep a piece of stainless steel or drill out a rivet. The Walter 01A507 7/64" SST+ Drill Bit is built to solve exactly that problem. Unlike standard high-speed steel bits that burn up the moment they touch hardened metal, these bits are crafted from a premium cobalt blend. This material composition gives the bit the heat resistance needed to cut through stainless steel, mild steel, and non-ferrous metals without losing its edge. It is the reliable partner you need in your shop when precision and toughness count.

Designed with the fabricator in mind, the SST+ series features a unique "High Flow" flute shape. When you are drilling deep or pushing hard to get the job done, this design pulls chips out of the hole faster than standard bits. This means less heat buildup—the enemy of any cutting tool—and a faster cut. You spend less time fighting the drill and more time fabricating. The bronze surface treatment further aids this process by letting the bit glide through the metal, reducing the effort needed to punch through thick plate or tubing.

One of the best features for welders working with pipe or tubing is the bit's ability to bite instantly. The tip geometry is designed to self-center, meaning it won't skate across the surface of a round pipe when you start your hole. This accuracy saves you from marring your workpiece and ensures your holes are exactly where you need them. Whether you are drilling pilot holes for larger fasteners or clearing out spot welds, this 7/64" bit offers the control you need.

Durability is key in a welding shop. The fully ground body of the Walter SST+ ensures that the bit resists snapping under torque, a common failure point for lesser bits. By investing in a high-quality bit like the 01A507, you reduce the number of trips to the tool crib for replacements, saving money and keeping your project on schedule. Add the Walter SST+ to your arsenal and experience the difference a professional-grade cutting tool makes.
