01A524 - Walter SST+ 3/8-Inch Cobalt Drill Bit for Stainless Steel

Industrial Grade Drilling Precision

The Walter 01A524 3/8" SST+ Drill Bit is engineered to redefine efficiency in industrial maintenance and repair operations. Built with a premium cobalt blend, this drill bit is specifically designed to withstand the high thermal stresses encountered when drilling through tough materials like stainless steel and hard alloys. Unlike standard high-speed steel bits that dull quickly under heat, the SST+ maintains its cutting edge longer, ensuring consistent performance and reducing the frequency of tool replacements.

At the heart of its performance is the exclusive "High Flow" flute design. This geometry is critical for deep hole drilling and rapid production environments, as it effectively evacuates chips from the hole to prevent clogging and heat buildup. The heavy-duty, fully ground body construction ensures the bit runs true with minimal vibration, which is essential for maintaining hole accuracy and protecting the drill press or power tool bearings. The specialized bronze SST surface treatment further enhances durability by acting as a lubricant, reducing friction during the cut.

For MRO professionals, versatility is key. This bit excels not only in stainless steel but also in mild steel and non-ferrous metals. Its robust web design resists snapping, making it a reliable choice for portable drilling applications where stability can be compromised. Whether you are tapping new threads or clearing out broken bolts, the Walter SST+ 3/8" bit delivers the reliability required for critical maintenance tasks.
