05A011 - Walter SST Annular Cutter 11/16 Inch x 1 Inch Depth

High-Performance Drilling with Walter SST Core Cutters

The Walter SST Core Cutter (SKU: 05A011) represents the pinnacle of annular cutter technology, designed specifically for industrial professionals who demand precision and speed. Measuring 11/16 inches in diameter with a 1-inch depth of cut, this tool is engineered to outperform standard twist drills in almost every metric. The secret lies in Walter's proprietary SST (Super Surface Treatment), a specialized bronze coating that dramatically alters the friction coefficient of the tool. By reducing friction between the cutter and the workpiece, heat generation is minimized, which is the primary cause of tool failure. This results in a cutter that stays sharper for longer, even when tackling tough materials like stainless steel and structural steel.

Efficiency is key in any production environment, and the Walter SST Core Cutter delivers by removing material only at the periphery of the hole, ejecting a solid slug. This method requires significantly less horsepower and thrust than solid drill bits, allowing for faster penetration rates and less wear on your magnetic drilling unit. The fully ground, extra-large flutes are designed to evacuate chips rapidly, preventing clogging and binding deep in the cut. Whether you are working on a remote job site or in a high-production fabrication shop, the reliability of this cutter ensures consistent hole sizes with a burr-free finish that often eliminates the need for secondary reaming or deburring operations.

Compatibility is never an issue thanks to the universal shank design. This feature allows the 05A011 to fit securely into a wide range of magnetic drills and stationary machines without the need for complex adapters. The robust tooth geometry is optimized to handle the shock and stress of heavy-duty drilling, making it an ideal choice for drilling through plates, pipes, and profiles. When precision, speed, and tool longevity are non-negotiable, the Walter SST Core Cutter is the superior choice for your metalworking needs.
