01J014 - Walter SST+ #14 Cobalt Stub Drill Bit for Sheet Metal

Maximum Rigidity for Precision Drilling

The Walter #14 SST Stub Drill is an industrial-grade cutting tool engineered specifically to address the common challenges faced when drilling sheet metal and thin-walled profiles. Unlike standard jobber-length bits, this stub drill features a significantly shorter overall length and flute geometry. This compact design inherently increases the rigidity of the bit, virtually eliminating the flexing and vibration that lead to premature breakage. For maintenance, repair, and operations (MRO) professionals, this means fewer broken bits and less downtime on the shop floor.

Advanced Cobalt Formulation

Manufactured from a robust cobalt blend, the Walter SST Stub Drill is built to withstand the high temperatures generated when drilling hard materials like stainless steel and other ferrous alloys. The addition of cobalt to the high-speed steel matrix improves red hardness, allowing the bit to maintain its cutting edge longer than standard HSS bits. This durability is further enhanced by Walter's proprietary bronze SST surface treatment, which reduces friction at the cutting interface and promotes efficient chip evacuation, preventing heat buildup that can work-harden the material.

Optimized for Portable Tools

While excellent in stationary drill presses, the Walter #14 SST Stub Drill truly excels in portable drilling applications. The self-centering split point design bites into the material immediately upon contact, preventing the "walking" or skating often experienced with standard chisel-point bits. This feature allows for precise hole placement without the need for a center punch. Combined with the breakage-resistant short profile, this bit is the ideal choice for operators working with hand drills in awkward positions or on curved surfaces where stability is paramount.
