01A027 - Walter SST+ 27/64" Cobalt Jobber Drill Bit with Quick Shank

High-Performance Cobalt Drilling Solution

The Walter 01A027 27/64" SST Jobber Drill Bit represents the pinnacle of drilling technology for industrial maintenance and fabrication. Engineered from a premium cobalt blend, this bit is designed to withstand high temperatures and mechanical stress, making it an exceptional choice for drilling through mild steel, aluminum, and thin gauge metals. The robust construction ensures that the cutting edges remain sharp longer than standard high-speed steel bits, reducing downtime and replacement costs.

A standout feature of this tool is the exclusive Quick Shank technology. Designed with longitudinal flats, the shank ensures a positive lock within the chuck, completely eliminating the frustration of bit slippage. This secure grip translates to efficient torque transfer, which is critical when working with tough materials or when precision is paramount. The bit also features a heavy-duty fully ground body with a back taper, which helps to reduce friction and prevent binding inside deep holes.

For precision starting, the SST bit utilizes a self-centering "Speed Tip." This advanced point geometry allows the operator to start drilling immediately without the need for a center punch, even on curved or round surfaces. Finished with a special bronze SST surface treatment, the bit sheds chips effectively and resists heat buildup, ensuring consistent performance in demanding environments.
