05A502 - Walter 2-1/8 Inch x 2 Inch SST Core Cut Annular Cutter

High-Performance Drilling with Walter SST Core Cut Technology

The Walter 05A502 is a premium 2-1/8" x 2" annular cutter designed to meet the rigorous demands of modern metal fabrication. Part of the renowned Core Cut series, this tool integrates Walter's exclusive Super Speed Tip (SST) technology. The SST surface treatment is a critical advancement in cutting tool engineering; it effectively eliminates porosity on the cutter's surface. By creating an exceptionally smooth finish, the treatment significantly reduces friction between the tool and the workpiece. This reduction in friction is paramount for minimizing heat generation—the primary cause of tool failure—thereby extending the lifespan of the cutter and allowing for higher drilling speeds.

Precision Engineering for Superior Results

Beyond its surface treatment, the 05A502 features a sophisticated geometric design. The cutter is equipped with fully ground, extra-large flutes. This design choice is essential for deep hole drilling, as it facilitates the rapid evacuation of chips and swarf. Efficient chip removal prevents clogging and heat buildup, ensuring that the cutter maintains its cutting edge for longer periods. The tooth geometry is optimized to slice through tough materials like stainless steel and structural steel with minimal resistance, producing clean, burr-free holes that often require no secondary finishing operations.

Versatility and Compatibility

Designed with the industrial user in mind, this Core Cut unit features a universal shank. This standardized connection ensures compatibility with a vast array of magnetic drilling units and stationary drill presses available on the market. Whether you are working in a fabrication shop or on a remote job site, the Walter 05A502 provides the reliability and performance necessary to execute large-diameter drilling tasks with precision. It is specifically engineered to handle a broad spectrum of materials, including aluminum, mild steel, and hard stainless steel alloys, making it a versatile addition to any machinist's toolkit.
