05A010 - Walter SST Core Cut Annular Cutter 5/8-Inch x 1-Inch

High-Performance Drilling with Walter SST Core Cut Technology

The Walter 05A010 SST Core Cut Annular Cutter represents the pinnacle of drilling efficiency for industrial fabrication. Designed with a 5/8-inch diameter and a 1-inch depth of cut, this tool is engineered to meet the rigorous demands of modern metalworking shops. The defining feature of this series is the exclusive SST (Super Surface Treatment), a specialized bronze coating that significantly alters the performance characteristics of the cutter. By eliminating microscopic porosity on the tool's surface, the SST treatment creates an exceptionally smooth exterior that drastically reduces friction during operation. This reduction in friction is critical for minimizing heat generation, which is the primary cause of tool failure and work hardening in sensitive materials like stainless steel.

Beyond its surface treatment, the geometry of the Walter SST Core Cut is optimized for rapid material removal. The cutter features fully ground, extra-large flutes that facilitate the immediate evacuation of chips. In deep hole drilling, chip packing can often lead to binding or breakage; however, Walter's design ensures that debris is cleared efficiently, allowing the cutter to maintain high rotational speeds without bogging down. This makes it an ideal choice for high-volume production environments where cycle time is a key performance indicator. The universal shank design further enhances its versatility, ensuring compatibility with a wide range of magnetic drilling units commonly found in maintenance, repair, and operations (MRO) inventories.

For Josef Gas customers, reliability and precision are paramount. This annular cutter delivers a close-tolerance hole with a superior surface finish that often eliminates the need for secondary operations like reaming or deburring. Whether working on structural steel frameworks or precision aluminum components, the 05A010 provides consistent, high-quality results. Its robust construction allows it to withstand the mechanical stresses of heavy-duty drilling while maintaining a sharp cutting edge longer than standard high-speed steel alternatives. Investing in Walter SST technology means investing in reduced downtime and lower cost-per-hole for your fabrication projects.
