05F120 - Walter 20mm Carbide Tipped Annular Cutter - 30mm Depth

High-Performance Drilling for Tough Materials

The Walter 05F120 Carbide Core Cut Annular Cutter is a premium industrial tooling solution designed to tackle the most demanding hole-making applications. Engineered with high-grade tungsten carbide inserts, this 20mm diameter cutter is built to penetrate materials that typically challenge or destroy standard High-Speed Steel (HSS) bits. With a cutting depth of 30mm, it is perfectly sized for drilling through thick plates, structural beams, and heavy-duty piping.

What sets the Walter Carbide Core Cut apart is its ability to maintain hardness and cutting edge integrity at high temperatures. When drilling through abrasive materials like cast iron or work-hardening metals like stainless steel, friction generates intense heat. Traditional bits soften and dull under these conditions, but Walter's carbide tips remain rigid and sharp, delivering consistent performance hole after hole. This durability translates directly to reduced downtime for tool changes and lower cost-per-hole in production environments.

Advanced Geometry for Efficiency

Beyond raw material hardness, the 05F120 features a sophisticated flute and body design. The specialized geometry promotes rapid chip evacuation, preventing clogging that can lead to binding or overheating. This design allows operators to run their magnetic drilling units at higher speeds and feeds, significantly improving productivity. Furthermore, the cutter requires less physical exertion to penetrate the workpiece, reducing operator fatigue during long shifts.

Versatility in Application

This annular cutter is not limited to flat, mild steel plates. It excels on irregular surfaces, curved pipes, and overlapping holes where interrupted cuts can shatter lesser tools. Whether you are working on-site repairing heavy equipment, fabricating structural steel in the shop, or drilling rail tracks, the Walter Carbide Core Cut offers the reliability and precision required for professional results. It is compatible with standard magnetic drilling units, making it a versatile addition to any metalworker's arsenal.
