Walter #19 Cobalt Stub Drill Bit for Sheet Metal

Heavy-Duty Drilling Solution for Welders and Fabricators

For welders and metal fabricators, a broken drill bit is more than just an annoyance—it's a stoppage in work and a potential safety hazard. The Walter #19 SST Stub Drill (SKU: 01J019) is engineered to solve the specific frustrations of drilling through sheet metal and stainless steel. Known in the industry for its "stub" length, this screw machine length drill bit offers superior strength compared to standard length bits. Because the flute and overall length are shorter, the bit is far less prone to flexing under load. This rigidity is critical when you are leaning into a cut with a hand drill or working in tight spaces where a long bit would be unwieldy or prone to snapping.

Fabricators often deal with a variety of metals, from mild steel to hardened stainless. The Walter SST Stub Drill is manufactured from a premium cobalt blend, giving it the red-hardness required to cut through tough stainless steel without dulling instantly. Standard bits often burn up when facing the work-hardening properties of stainless, but the cobalt content in this Walter bit ensures it stays sharp longer, cutting cleanly through the material. Additionally, the bronze SST surface treatment acts as a lubricant and heat shield, reducing friction and allowing the bit to clear chips efficiently. This prevents the bit from binding in the hole, which is a common cause of breakage in sheet metal applications.

One of the standout features for daily use is the 135° split point (typical for this class). This geometry allows for instant penetration. You can place the tip exactly where you need the hole and pull the trigger—no walking, no skating, and no need to waste time with a center punch. This is perfect for drilling out rivets, creating pilot holes for welding, or installing fasteners in sheet metal enclosures. The clean cutting action leaves round, burr-free holes, reducing the amount of post-drill cleanup or deburring required before the next stage of fabrication.

Equip your shop with the Walter 01J019 and experience the difference that a purpose-built tool makes. It is designed to withstand the high torque and feed pressure often applied in welding shops. By choosing a drill bit that resists breakage and maintains its edge, you save money on replacements and keep your projects moving forward. Whether you are working on automotive body panels, HVAC ducting, or custom stainless enclosures, this stub drill provides the reliability and performance professional welders demand.
