When you are out in the shop or on a job site, a broken drill bit can stop production in its tracks. The Walter #21 SST Stub Drill Bit is built to withstand the rigorous demands of welding and metal fabrication. Known for its toughness, this bit utilizes a high-quality cobalt blend that resists the high temperatures generated when drilling through hardened welds or stainless steel panels.
The stub (short) length is a favorite among fabricators for good reason. The shorter shaft offers superior strength and rigidity, making it much harder to snap when you are leaning into a hand drill. This rigidity is crucial when drilling out spot welds or creating rivet holes in sheet metal, where a standard bit might flex and walk. With the Walter SST Stub Drill, you get a straight, clean hole every time.
Walter has equipped this bit with a 135° split point that bites into the metal instantly. This means no skating across the surface and scratching your workpiece—just point and drill. The exclusive Bronze SST finish helps keep the bit cool and slick, preventing the metal from galling or sticking to the flutes. For welders who need tools that work as hard as they do, this drill bit is an essential addition to your toolbox.
From automotive bodywork to heavy industrial repairs, the 01J021 is designed to perform. It handles thin gauge materials with ease, producing round, burr-free holes that are ready for fasteners or welding. Stop wasting money on cheap bits that burn out or snap; upgrade to Walter's industrial standard and experience the difference in speed and longevity.
