05A015 - Walter SST Core Cut Annular Cutter 15/16-Inch x 1-Inch Depth

High-Performance Drilling with Walter SST Core Cutters

The Walter 15/16" x 1" SST Core Cut Annular Cutter (05A015) represents the pinnacle of drilling efficiency for industrial fabrication. Designed to meet the rigorous demands of modern metalworking, this core cutter features Walter's exclusive Super Speed Tip (SST) technology. Unlike traditional twist drills that must convert the entire area of the hole into chips, this annular cutter removes only the periphery of the hole, ejecting a solid slug. This method requires less energy and time, making it the preferred choice for drilling large diameter holes in structural steel, stainless steel, and aluminum.

Advanced Bronze SST Surface Treatment

What sets the 05A015 apart is its state-of-the-art bronze SST surface treatment. This specialized coating is engineered to drastically reduce friction between the tool and the workpiece. By minimizing friction, the cutter generates significantly less heat during operation. Heat is the primary enemy of cutting tools, leading to premature wear and failure. The SST coating acts as a thermal barrier and lubricant, ensuring the cutter stays cooler and retains its cutting edge for longer periods, even when drilling through tough materials like stainless steel.

Precision Engineering and Design

Every aspect of the Walter SST Core Cut is designed for performance. The cutter features fully ground, extra-large flutes that provide a clear path for rapid chip evacuation. Efficient chip removal is critical in deep hole drilling to prevent binding and overheating. The modern tooth geometry is optimized to bite into the material cleanly, producing a flawlessly smooth finish that is virtually free of porosity. This often eliminates the need for secondary reaming or deburring operations, saving valuable production time.

Universal Compatibility

Versatility is key in a busy workshop. The Walter 05A015 is equipped with a universal shank, making it compatible with a wide range of magnetic drilling units and stationary machines. Whether you are working on-site erecting structural steel or in a fabrication shop processing heavy plate, this cutter delivers consistent, reliable results. Its robust construction ensures it can handle the torque and pressure required for heavy-duty drilling applications while maintaining precision accuracy.
