Walter SST+ Double-Ended Cobalt Stub Drill Bit

Heavy-Duty Drilling for Fabrication and Auto Body Work

When it comes to metal fabrication, especially in automotive and sheet metal applications, the durability of your consumables can make or break your workflow. The Walter SST Double-Ended Stub Drill (01K151) is engineered to withstand the rigorous demands of the welding and fabrication industry. Built with a premium cobalt blend, this drill bit is designed to cut through thin materials where standard bits often fail or snap. The cobalt composition provides excellent heat resistance, allowing you to drill through tough alloys and stainless steel sheets without burning out the tip prematurely.

One of the biggest frustrations in sheet metal work is drill bit breakage. Long, flexible bits can snap when they bite into thin metal, causing delays and potential injury. The Walter SST features a stub length profile, which is significantly shorter and more rigid than standard jobber bits. This rigidity ensures direct force transfer and precise hole placement, reducing the risk of the bit wandering or snapping under pressure. It is the ideal solution for drilling out spot welds, installing rivets, or prepping surfaces for welding in auto body shops and aerospace maintenance facilities.

The "Double-Ended" feature is a game-changer for shop efficiency. Instead of discarding a bit the moment it dulls, you simply reverse it in the chuck and keep drilling. This 2-in-1 design means you carry fewer bits in your pocket while getting twice the work done. Whether you are working on aluminum siding, steel panels, or custom fabrication projects, the Walter SST Double-Ended Stub Drill delivers the reliability and performance professional welders demand. It puts black oxide competitors to shame by offering a solution that stays sharp, cuts true, and lasts longer.

Why Choose Walter SST Stub Drills?

• Superior Rigidity: Short length prevents flexing and snapping on hard surfaces.
• Double the Value: Two cutting ends mean you buy fewer bits over time.
• Versatile Performance: Excellent for drilling rivets, sheet metal, and thin-wall tubing.
