01B516 - Walter SST+ #16 Cobalt Jobber Drill Bit

Premium Performance for Industrial Drilling

The Walter 01B516 #16 SST+ Jobber Drill Bit represents the pinnacle of drilling technology for industrial maintenance and fabrication. Engineered by Walter Surface Technologies, the SST+ line is specifically formulated with a cobalt blend High Speed Steel (HSS) that withstands the extreme temperatures generated when drilling hard materials like stainless steel. Unlike standard black oxide bits that can dull quickly under thermal stress, the SST+ maintains its cutting edge hardness, ensuring consistent performance hole after hole.

Precision is paramount in professional environments, and the SST+ delivers with its exclusive "Speed Tip" design. This self-centering geometry bites into the material immediately upon contact, effectively eliminating the phenomenon of "walking" across the workpiece. This feature removes the necessity for center punching, streamlining your workflow and reducing setup time. The bit also features a unique bronze SST surface treatment which acts as a lubricant to reduce friction, further aiding in heat dissipation and chip flow.

Structurally, the bit is designed with a "high flow" flute geometry and a back-tapered body. These engineering choices maximize chip evacuation rates, preventing clogging and binding deep in the hole. Whether used in a stationary drill press or a portable hand drill, the Walter 01B516 provides the torque transfer and cutting efficiency required for MRO professionals demanding the best tools for metalworking.
