05D500 - Walter 2-Inch Carbide Tipped Annular Cutter 2-Inch Depth

Precision Engineering for Hardened Materials

The Walter 05D500 2" x 2" Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for industrial applications involving difficult-to-machine materials. Unlike standard High-Speed Steel (HSS) cutters which can suffer from rapid edge degradation when facing work-hardening alloys, this carbide-tipped tool is engineered to withstand extreme thermal and mechanical stress. The cutter features high-grade tungsten carbide inserts that are brazed onto a specialized alloy body, providing the hardness required to penetrate stainless steel, cast iron, and other tough alloys with exceptional efficiency.

One of the critical technical features of this cutter is its advanced flute design. In deep hole drilling—up to the 2-inch depth capacity of this unit—chip evacuation is paramount to preventing heat buildup and binding. The Walter Carbide Core Cut utilizes a geometry that aggressively ejects chips, keeping the cutting interface cool and reducing the torque load on the magnetic drilling unit. This design allows operators to run machines at higher RPMs and feed rates, significantly reducing cycle times in production environments. Furthermore, the carbide tips are precision-ground to ensure concentricity, minimizing vibration and ensuring hole tolerance accuracy.

This tool is particularly advantageous for MRO (Maintenance, Repair, and Operations) professionals dealing with unknown or mixed materials. Whether the task involves drilling through structural steel with hard scale, abrasive cast iron components, or vibration-prone uneven surfaces, the 05D500 maintains its cutting aggression throughout its lifespan. The robust construction also makes it suitable for drilling into composite materials and non-ferrous metals like aluminum and copper, where material adhesion can be a problem for lesser tools. By integrating superior metallurgy with functional design, Walter provides a solution that lowers the cost-per-hole through extended durability and reduced downtime.
