01D575 - Walter SST+ 7.50mm Cobalt Drill Bit for Stainless Steel

High-Performance Walter SST+ 7.50mm Drill Bit

The Walter SST+ 7.50mm Drill Bit (SKU: 01D575) is a premium cutting tool engineered to meet the demanding requirements of industrial fabrication and maintenance. Recently upgraded with a specialized cobalt blend, this drill bit offers exceptional hardness and heat resistance, making it the ideal choice for drilling through tough materials such as stainless steel, mild steel, and various non-ferrous alloys. The addition of cobalt ensures the cutting edge retains its sharpness longer, significantly reducing tool replacement frequency and downtime in high-volume production environments.

Efficiency is at the heart of the SST+ design. It features a unique "high flow" flute geometry that rapidly evacuates chips from the hole, preventing heat buildup and clogging—common causes of bit failure. The body of the bit is back-tapered to minimize friction against the sidewalls, ensuring smoother operation and cleaner holes. Furthermore, the exclusive bronze SST surface treatment acts as a high-performance lubricant, reducing torque requirements and protecting the bit from wear.

Designed for versatility, the Walter 01D575 excels in both stationary drill presses and portable hand drills. Its geometry is specifically tuned to bite into round surfaces, such as pipes and tubing, without "walking," ensuring precise hole placement every time. Whether used for general maintenance or precision manufacturing, this drill bit delivers reliable, professional-grade performance across a wide range of metals.
