01D567 - Walter SST+ 6.7mm Cobalt Blend Drill Bit for Stainless Steel

High-Performance Drilling Solution for Tough Alloys

The Walter SST+ 6.7mm Drill Bit (SKU: 01D567) represents the pinnacle of drilling technology for industrial applications requiring precision and durability. Engineered by Walter Surface Technologies, this bit is specifically designed to overcome the common challenges associated with drilling hard metals, particularly stainless steel. The core of its performance lies in its material composition; the bit is crafted from a specialized cobalt blend that provides exceptional heat resistance. This is critical when drilling high-tensile materials that generate significant friction, as it prevents the cutting edge from softening and dulling prematurely.

Beyond its metallurgy, the SST+ features a sophisticated geometric design. The "high flow" flute configuration is engineered to maximize chip evacuation rates. In deep hole drilling or when working with materials that produce long, stringy chips, efficient evacuation is essential to prevent clogging and heat concentration. Furthermore, the bit incorporates a back-tapered body design. This subtle reduction in diameter behind the cutting head significantly reduces surface contact with the hole walls, thereby minimizing friction and torque requirements. This design feature not only extends the life of the bit but also reduces the load on the drilling equipment.

The surface of the 01D567 is finished with Walter's exclusive Bronze SST treatment. This treatment acts as a permanent lubricant, further reducing friction and allowing for higher drilling speeds without compromising tool life. Whether utilized in stationary drill presses or portable hand drills, the self-centering split point ensures accurate hole placement without the need for pilot holes or center punching. For MRO professionals seeking to optimize their drilling cycles and reduce consumable waste, the Walter SST+ 6.7mm bit offers a technically superior solution that delivers consistent, measurable results.
