01D565 - Walter SST+ 6.50mm Cobalt Blend Drill Bit for Stainless Steel

High-Performance Drilling with Walter SST+ Technology

The Walter 01D565 6.50mm SST+ Drill Bit represents the pinnacle of drilling efficiency for industrial applications. Designed by Walter Surface Technologies, this tool is engineered to address the common challenges faced by maintenance, repair, and operations (MRO) professionals when working with tough alloys. The core of this drill bit's performance lies in its enhanced cobalt blend. Unlike standard high-speed steel bits that may soften or dull rapidly under high thermal loads, the cobalt infusion provides exceptional heat resistance, maintaining the cutting edge's hardness even when drilling through work-hardened stainless steel.

Efficiency in a production environment is measured by the number of holes produced per tool and the speed at which they are drilled. The Walter SST+ incorporates a "High Flow" flute design, a critical feature that accelerates chip evacuation. By effectively removing debris from the hole, the bit prevents heat buildup caused by friction and chip recutting. This is further complemented by the bit's back tapered body, a geometric optimization that reduces surface contact between the tool and the sidewalls of the hole, thereby minimizing drag and the risk of binding.

Durability is further enhanced by Walter's exclusive bronze SST surface treatment. This specialized coating acts as a lubricant and a thermal barrier, significantly extending the tool's lifespan. Whether utilized in a stationary drill press for precision fabrication or a portable drill for on-site repairs, the 01D565 delivers consistent, reliable results. It is an indispensable asset for facilities processing mild steel, non-ferrous metals, and particularly stainless steel, where precision and tool longevity are paramount.

Key Industrial Benefits

Investing in Walter SST+ drill bits translates to reduced downtime for tool changes and lower overall consumable costs. The 6.50mm size is a standard metric dimension essential for various tapping and clearance hole applications. By choosing a bit designed specifically for high-tensile materials, operators ensure cleaner cuts, better dimensional accuracy, and a safer drilling process.
