05A312 - Walter SST Core Cut Annular Cutter 3/4" x 2" Universal Shank

High-Performance Drilling Technology

The Walter SST Core Cut Annular Cutter (SKU: 05A312) represents a significant advancement in hole-making technology for industrial applications. Engineered with Walter's proprietary Super Speed Tip (SST) surface treatment, this 3/4-inch diameter cutter is designed to eliminate microscopic porosity on the tool's surface. This treatment creates an exceptionally smooth finish that drastically reduces friction between the cutter and the workpiece. Consequently, heat generation—the primary cause of tool failure in drilling operations—is minimized, allowing the cutter to maintain its hardness and cutting edge for longer periods, even under heavy loads.

This cutter features a 2-inch depth of cut, making it suitable for drilling through thick plates, structural beams, and heavy-wall pipe. The geometry of the cutter includes fully ground, extra-large flutes which are critical for deep hole drilling. These flutes facilitate the rapid evacuation of chips, preventing clogging and binding that can damage both the tool and the machine. The modern tooth design is optimized to balance cutting forces, ensuring a stable drilling process and a burr-free finish that often eliminates the need for secondary reaming or deburring operations.

Compatibility is key in MRO environments, and the 05A312 is equipped with a universal shank. This design ensures seamless integration with a wide variety of magnetic drilling units and stationary drill presses available in the market. Whether working with mild steel, structural steel, or difficult-to-machine stainless steel, the Walter SST Core Cut delivers consistent, precise performance. The bronze SST coating not only identifies the tool but serves as a functional barrier against wear, ensuring that this core cutter remains a reliable asset in any professional tool crib.
