05F140 - Walter 40mm Carbide Tipped Annular Cutter 30mm Depth

Precision Drilling for Hardened Materials

The Walter 05F140 Carbide Core Cut annular cutter represents the pinnacle of drilling technology for industrial applications requiring precision and durability. Engineered with high-grade carbide inserts, this 40mm diameter cutter is specifically designed to tackle the most challenging materials in the metalworking industry, including stainless steel, cast iron, and high-tensile alloys. Unlike traditional High-Speed Steel (HSS) cutters, the Carbide Core Cut series maintains its hardness at high temperatures, allowing for significantly faster feed rates and reduced cycle times.

This cutter features a 30mm depth of cut, making it versatile for a wide range of plate thicknesses and structural components. The advanced body design incorporates a specialized flute geometry that optimizes chip evacuation, preventing heat buildup and ensuring a clean, burr-free finish. This is particularly critical when working with materials that have a tendency to work-harden, such as austenitic stainless steels. By reducing the cutting effort required, the Walter Carbide Core Cut not only extends the life of the tool but also reduces wear on the magnetic drilling unit's motor.

Reliability is paramount in industrial MRO and fabrication environments. The 05F140 is built to deliver consistent performance even in uneven or difficult-to-machine surfaces. Whether utilized in a workshop setting or for on-site repairs, this cutter provides the stability and cutting aggression needed to produce accurate, large-diameter holes efficiently. It is an essential tool for professionals demanding the highest standards of quality and productivity in their drilling operations.
