05A109 - Walter SST Core Cut Annular Cutter 1-9/16 Inch x 1 Inch Depth

High-Performance Drilling with Walter SST Technology

The Walter 05A109 SST Corecut is a premium annular cutter designed to redefine efficiency in industrial drilling operations. Engineered with Walter's proprietary Surface Treatment Technology (SST), this 1-9/16" diameter cutter features a distinctive bronze coating that serves a critical function beyond aesthetics. The SST coating significantly reduces the coefficient of friction between the tool and the workpiece. In metalworking, friction is the primary enemy of tool life, generating excessive heat that dulls cutting edges and hardens the material being drilled. By minimizing this friction, the SST Corecut operates at cooler temperatures, preserving the temper of the high-speed steel and extending the overall lifespan of the cutter, even when tackling tough materials like stainless steel and structural alloys.

Beyond the surface treatment, the physical geometry of the cutter is optimized for heavy-duty performance. It boasts fully ground, extra-large flutes that provide a clear path for chip evacuation. Efficient chip removal is essential in deep hole drilling to prevent binding and breakage. The modern tooth design works in tandem with these flutes to slice through metal aggressively yet smoothly, requiring less horsepower from the magnetic drilling unit. This results in faster penetration rates and improved productivity for machine operators.

Versatility is a key component of the 05A109's design. It features a universal shank that ensures compatibility with a wide array of magnetic drilling machines and stationary drill presses available in the market. Whether you are working in a fabrication shop or on a remote job site, this cutter integrates seamlessly into your existing tooling setup. The 1-inch depth of cut is ideal for standard plate drilling applications, providing a clean, burr-free hole that typically requires no secondary finishing operations. For industrial MRO professionals seeking reliability and precision, the Walter SST Corecut stands out as a superior choice.
