05A611 - Walter SST Core Cut Annular Cutter 11/16 in x 3 in Depth

High-Performance Annular Cutter for Industrial Drilling

The Walter 05A611 SST Corecut is a precision-engineered annular cutter designed to meet the rigorous demands of modern metalworking. Measuring 11/16 inches in diameter with a substantial 3-inch depth of cut, this tool utilizes Walter's proprietary Super Speed Tip (SST) technology. The SST surface treatment is a critical advancement in cutter design; it effectively eliminates surface porosity, creating an exceptionally smooth exterior. This smoothness drastically reduces friction between the tool and the workpiece, which is the primary cause of heat buildup during heavy drilling operations. By maintaining lower operating temperatures, the cutter retains its hardness longer and resists wear, ensuring a prolonged service life even in tough environments.

Mechanically, the cutter is designed for maximum efficiency. It features fully ground, extra-large flutes that facilitate rapid chip evacuation. Efficient chip removal is vital for deep hole drilling, as it prevents clogging and binding that can damage the tool or the machine. The cutter's geometry is optimized to handle a variety of materials, including mild steel, structural steel, stainless steel, and aluminum. The universal shank design allows this cutter to be compatible with a wide range of magnetic drilling units and stationary machines, making it a versatile choice for machine shops and manufacturing facilities.

In addition to its durability, the Walter SST Corecut delivers superior hole quality. The precision-ground teeth cut cleanly and accurately, leaving a burr-free finish that often eliminates the need for secondary reaming or deburring. This efficiency translates to reduced cycle times and increased productivity for industrial operators.
