01H030 - Walter 15/32 Sst Stub Drill

The Fabricator's Choice for Sheet Metal and Stainless

For professional welders and fabricators, the Walter 01H030 15/32" SST Stub Drill represents the ultimate in durability and control. Fabrication work often involves drilling hundreds of holes in sheet metal, removing spot welds, or prepping surfaces for assembly. In these high-volume applications, a snapped drill bit is not just an annoyance—it's a safety hazard and a productivity killer. The "stub" or screw machine length of this bit provides exceptional rigidity, making it virtually unbreakable under normal operating conditions. This allows you to apply the necessary feed pressure to cut through work-hardened stainless steel without fear of the bit flexing or shattering.

Designed specifically for the metalworking trade, this drill bit features a 135° split point that bites into the metal instantly. This is a game-changer when working on polished stainless steel or aluminum, where a slipping drill bit can ruin an expensive workpiece. The self-centering action means you can skip the center punch step, speeding up your workflow significantly. The compact size also allows you to fit your drill into tight corners, wheel wells, and inside box sections where a standard length bit simply wouldn't fit.

The Walter SST (Super Speed Tip) technology incorporates a unique bronze surface treatment that promotes chip evacuation and heat dissipation. Heat is the enemy of any cutting tool, especially when drilling stainless steel. By keeping the cutting edge cooler, the SST Stub Drill maintains its hardness longer, giving you more holes per bit. Whether you are drilling pilot holes for fasteners or clearing out blocked passages, this tool provides the professional performance welders expect from the Walter brand.
