01J017 - Walter SST+ Stub Drill Bit 17/64" Cobalt Blend

Heavy-Duty Walter 17/64" SST+ Cobalt Stub Drill Bit

Maximize your drilling efficiency with the Walter 01J017 SST+ Stub Drill Bit, engineered for the rigorous demands of industrial metalworking. This 17/64" bit is crafted from a premium cobalt HSS blend, offering superior hardness and heat resistance that is critical when drilling hard materials like stainless steel and automotive sheet metal. The robust construction ensures that the bit stays sharp cut after cut, reducing downtime and tool replacement costs.

The design of this bit focuses on stability and speed. Its short flute length and overall stub profile provide maximum rigidity, virtually eliminating the risk of snapping the bit during aggressive drilling or when applying side pressure. This makes it particularly effective for drilling out spot welds or working in confined spaces where long bits are impractical. The self-centering 135° split point ensures accuracy from the very first rotation, allowing for faster penetration rates.

Walter Surface Technologies has applied a special bronze surface treatment to the SST series, which aids in chip flow and reduces binding. This drill bit is an excellent choice for welders and fabricators who require reliable, high-speed drilling in diverse materials, including aluminum and structural steel. Trust in Walter's engineering to deliver a hole-making solution that combines durability, precision, and speed.
