01B511 - Walter SST+ Cobalt Jobber Drill Bit #11

Heavy-Duty Solution for Stainless Steel Drilling

Drilling through stainless steel requires a tool that can withstand extreme heat and abrasion. The Walter SST+ Drill Bit #11 is engineered specifically for this challenge. Built with a robust cobalt blend, this bit resists the high temperatures that typically destroy standard bits, ensuring a longer lifespan and fewer tool changes. For welders and fabricators, this means less downtime and more continuous work. The #11 wire gauge size (0.1910 inches) is precision-ground to exacting standards, providing the accuracy needed for critical fabrication tasks and tapping preparations.

The frustration of drill bit "walking" is a thing of the past with the Walter SST+ series. The advanced self-centering Speed Tip bites into the metal instantly, providing stability even on curved or irregular surfaces. This is a game-changer for field work where using a center punch isn't always feasible. The bit's aggressive cutting action is supported by a heavy-duty web construction that resists snapping under torque, giving you the confidence to apply the necessary feed pressure for hard metals.

Efficiency is further enhanced by the bit's specialized geometry. The high-flow flutes are designed to eject long, continuous chips rapidly, keeping the cutting zone clear and cool. A special bronze surface treatment acts as a lubricant and heat shield, further protecting the tool's integrity. Whether you are drilling out broken bolts, fabricating custom brackets, or installing hardware, the Walter SST+ #11 drill bit provides the speed, durability, and precision required for professional-grade results. It is compatible with all standard portable drills and stationary machine tools.
