01D590 - Walter 9.00Mm Sst Drill Bit

Cut Through Stainless Like Butter

Every welder knows the frustration of a dull drill bit—the smoke, the squealing, and the wasted time trying to push through a piece of steel that just won't yield. The Walter SST+ 9.00mm Drill Bit is the solution to those headaches. Built for the tradesman who needs reliable tools that work as hard as they do, this bit is infused with a cobalt blend that gives it the backbone to bite into metal and keep cutting long after standard bits have failed. If you frequently work with stainless steel, you know it has a tendency to work-harden if your bit slips or rubs; the SST+ is designed to penetrate immediately and cut freely, preventing that hardened glaze from forming.

The design of the Walter 01D590 isn't just about hardness; it's about usability. The bit features a special "high flow" flute shape that pulls chips out of the hole quickly. This means you don't have to constantly back the drill out to clear debris, allowing you to finish the hole in one smooth pass. Additionally, the back tapered body design prevents the sides of the bit from rubbing against the hole, which keeps the bit cooler and stops it from binding up—a common cause of snapped bits and wrist injuries when using high-torque hand drills.

Whether you are drilling out broken bolts, fabricating brackets, or installing hardware, the Walter SST+ gives you the confidence that you can get the job done right the first time. Its bronze SST finish isn't just for looks; it helps the bit slide through material with less resistance. Suitable for all portable drilling applications and stationary machines, this 9.00mm bit is a versatile workhorse for any welding shop or tool box. Stop burning through cheap bits and upgrade to a tool that actually cuts.
