01D542 - Walter SST+ 4.20mm Cobalt Drill Bit

High-Performance Walter SST+ 4.20mm Drill Bit for Industrial Applications

The Walter 01D542 4.20mm SST+ Drill Bit represents the pinnacle of drilling technology for industrial maintenance and fabrication. Engineered with an advanced cobalt blend, this drill bit is specifically designed to tackle the toughest materials, including stainless steel, mild steel, and non-ferrous metals. The inclusion of cobalt significantly increases the bit's heat resistance and hardness, allowing it to maintain a sharp cutting edge even under high-temperature drilling conditions often encountered in heavy-duty manufacturing environments.

One of the standout features of this drill bit is its "high flow" flute design. This geometry is optimized to evacuate chips rapidly from the hole, reducing heat buildup and preventing the bit from binding. Efficient chip removal is critical for maintaining drilling speed and accuracy, especially in deep hole applications. Furthermore, the back tapered body design minimizes contact between the bit and the sidewalls of the hole, reducing friction and torque requirements. This results in a smoother drilling action and less strain on both the tool and the drilling machine.

To further enhance performance, Walter has applied a proprietary bronze SST surface treatment. This treatment acts as a lubricant and a protective barrier, reducing friction at the cutting interface and preventing material adhesion (galling). The combination of the cobalt blend substrate and the bronze surface treatment ensures that the 01D542 delivers an expedited hole-drilling experience, capable of producing a greater number of holes per bit compared to standard high-speed steel alternatives. Whether used in stationary drill presses or portable hand drills, this bit offers consistent, reliable performance for professionals who demand the best.

In summary, the Walter 4.20mm SST+ Drill Bit is a robust solution for MRO professionals. Its ability to effortlessly drill through various metals makes it a versatile addition to any toolbox. The enhanced durability provided by the cobalt blend and bronze treatment translates to lower consumable costs and reduced downtime for bit changes, ultimately driving productivity in the workshop.
