01B517 - Walter SST+ Cobalt Jobber Drill Bit #17

Precision Drilling with Walter SST+ Technology

The Walter #17 SST+ Jobber Drill Bit (SKU: 01B517) is engineered to meet the rigorous demands of industrial maintenance, repair, and operations (MRO). Designed with a focus on efficiency and precision, this drill bit utilizes a proprietary cobalt blend that significantly enhances hardness and heat resistance. This material composition makes the SST+ series particularly effective when drilling through high-tensile materials such as stainless steel, where standard high-speed steel bits often fail due to thermal stress.

A standout feature of this tool is the exclusive "Speed Tip." This self-centering geometry eliminates the common issue of bit wandering, allowing operators to drill precise holes without the prerequisite of a center punch. This feature is invaluable in automated or stationary setups where accuracy is paramount, as well as in portable drilling applications where stability can be a challenge. The bit also features a heavy-duty web construction, which provides the structural integrity needed to resist breakage under high torque loads.

Thermal management is critical in metal drilling, and Walter addresses this with a specialized Bronze SST surface treatment. This coating reduces the coefficient of friction between the bit and the workpiece, allowing for higher drilling speeds while minimizing heat buildup. Coupled with a "High Flow" flute design that rapidly evacuates chips, and a back-tapered body that prevents binding, the Walter 01B517 delivers a smooth, efficient cutting action that prolongs tool life and improves productivity in the workshop.
