01D510 - Walter SST+ 1.0mm Cobalt Drill Bit for Stainless & Steel

High-Performance 1.0mm Cobalt Drill Bit for Industrial Applications

The Walter SST+ 1.0mm drill bit (SKU: 01D510) represents a pinnacle in drilling technology for maintenance, repair, and operations (MRO) environments. Engineered with a proprietary cobalt blend, this tool is specifically designed to withstand the high thermal stresses generated when machining hard materials such as stainless steel and other ferrous alloys. The inclusion of cobalt significantly extends the service life of the bit by maintaining hardness at elevated temperatures, a critical factor in continuous production or heavy-duty repair scenarios.

A key feature of the SST+ series is its unique Bronze SST surface treatment. This specialized coating reduces the coefficient of friction between the tool and the workpiece, facilitating smoother cutting action and reducing heat buildup. Combined with a "high flow" flute geometry, the bit efficiently evacuates chips, preventing clogging and localized overheating that can lead to premature tool failure. The back-tapered body design further enhances performance by minimizing contact with the sidewalls of the hole, thereby reducing torque requirements and preventing binding.

Designed for versatility, this 1.0mm bit excels in both stationary drill presses and portable power tools. Its robust construction allows for aggressive feed rates while maintaining precision. Whether dealing with mild steel, non-ferrous metals, or challenging stainless steel grades, the Walter SST+ delivers consistent, burr-free holes. It is an essential component for any industrial tool crib, offering reliability where standard high-speed steel (HSS) bits often fail.
