Walter SST+ #29 Cobalt Stub Drill Bit for Stainless Steel

Walter SST+ #29 Cobalt Stub Drill Bit: The Professional's Choice

Elevate your drilling capabilities with the Walter 01J029 SST+ Stub Drill Bit, a high-performance tool designed specifically for the rigors of industrial metalworking. This #29 wire gauge bit is crafted from a special cobalt blend, offering superior hardness and heat resistance compared to standard high-speed steel. It is the ideal solution for welders and fabricators working with challenging materials such as stainless steel, where maintaining a sharp cutting edge is critical for productivity and finish quality.

Unmatched Rigidity and Durability

One of the standout features of this bit is its "stub" or screw machine length. By shortening the overall length and the flutes, Walter has created a drill bit that offers maximum rigidity. This structural integrity makes the bit highly resistant to breakage, a common issue when applying heavy feed pressure or using portable drills in awkward positions. For automotive bodywork, HVAC installation, or general sheet metal fabrication, this added durability translates to fewer broken bits and less downtime.

Designed for Efficiency

The Walter SST+ series incorporates a heavy-duty split point geometry that ensures rapid penetration. This design cuts aggressively from the moment it touches the metal, requiring less force from the operator and preventing the bit from slipping across the surface. Combined with the exclusive bronze SST surface treatment, the bit runs cooler and clears chips more effectively. This is particularly beneficial when drilling round surfaces or pipes, where precision starting is difficult with lesser tools.

Applications

This drill bit is versatile and reliable, suitable for a wide range of materials including mild steel, aluminum, and non-ferrous alloys. However, it truly shines in stainless steel and sheet metal applications where its robust design and heat-resistant properties provide a distinct advantage. Equip your shop with Walter SST+ stub drills for reliable, precise holes every time.
