05D813 - Walter 13/16 Inch Carbide Tipped Annular Cutter 4 Inch Depth

Precision Engineering for Tough Alloys

The Walter 13/16" X 4" Carbide Core Cut (SKU: 05D813) represents the pinnacle of annular cutter technology, specifically engineered for industrial environments where material hardness and hole depth present significant challenges. Unlike traditional High-Speed Steel (HSS) cutters, this tool utilizes premium tungsten carbide tips. This metallurgical advantage allows the cutter to maintain its cutting edge at significantly higher temperatures, a critical factor when machining materials with low thermal conductivity such as stainless steel or abrasive materials like cast iron. The carbide inserts are brazed onto a specialized alloy body, providing the perfect balance of tip hardness and structural toughness to prevent shattering under load.

The geometry of the 05D813 is designed for high-efficiency chip evacuation. When drilling to a depth of 4 inches, chip packing is a common failure mode that can lead to heat buildup and tool breakage. Walter has engineered a unique flute design that actively channels swarf away from the cutting zone, ensuring that coolant can reach the cutting interface and that the tool runs cooler. This design enables operators to utilize faster feed rates and higher rotational speeds, directly translating to reduced cycle times in production environments. The cutter is manufactured to tight tolerances, ensuring hole concentricity and minimizing runout, which is essential for high-precision assembly work.

This tool is particularly effective for applications involving uneven surfaces or interrupted cuts, scenarios that often cause premature failure in lesser tools. The robust design of the Carbide Core Cut series absorbs the mechanical shock associated with entering and exiting irregular workpieces. Whether utilized in a stationary drill press or a portable magnetic drilling unit, the 05D813 delivers consistent, burr-free performance. It is an indispensable asset for MRO operations dealing with structural steel, heavy equipment repair, and custom fabrication of hard alloys.
