01A502 - Walter SST+ 1/32 Inch Cobalt Drill Bit for Stainless Steel

Premium Performance for Hard Metals

The Walter 01A502 1/32" SST+ Drill Bit represents the pinnacle of drilling technology for industrial maintenance and fabrication. Designed by Walter Surface Technologies, the SST+ (Super Speed Tip Plus) line is engineered to overcome the common challenges associated with drilling hard materials, particularly stainless steel. At the core of this tool is a proprietary cobalt blend high-speed steel (HSS) substrate. This material composition provides exceptional hot hardness, allowing the bit to maintain its cutting edge even under the high temperatures generated when drilling tough alloys.

One of the standout features of the 01A502 is its High Flow flute design. In small diameter drilling, such as 1/32 inch, chip evacuation is critical to preventing breakage. The specialized flute geometry of the SST+ ensures that chips are ejected rapidly, preventing clogging and reducing the heat friction that destroys lesser bits. Coupled with a heavy-duty, fully ground body, this bit offers superior concentricity and resistance to snapping under torque.

The bit also features Walter's exclusive Bronze SST surface treatment. This coating is not merely aesthetic; it significantly reduces the coefficient of friction between the bit and the workpiece. This reduction in friction translates to lower drilling temperatures and extended tool life. The 135° split point geometry is self-centering, eliminating the need for center punching and preventing the bit from "walking" across the surface of the material upon startup. For professionals requiring precision, durability, and efficiency in their drilling operations, the Walter SST+ 1/32" bit is the definitive choice.
