05D313 - 13/16 Inch x 2 Inch Carbide Tipped Annular Cutter

Precision Drilling for Hardened Materials

The Walter 05D313 Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for industrial applications involving difficult-to-machine materials. Engineered with high-grade tungsten carbide tips, this 13/16-inch diameter cutter is specifically designed to overcome the limitations of traditional High-Speed Steel (HSS) tooling. When faced with abrasive substrates like cast iron, or work-hardening materials such as stainless steel and exotic alloys, the Carbide Core Cut delivers consistent performance where other cutters fail. The 2-inch depth of cut capability allows for single-pass drilling through thick structural plates, significantly reducing cycle times in heavy fabrication environments.

Technically, the cutter features a sophisticated flute design that optimizes chip evacuation, a critical factor when drilling deep holes in materials that produce long, stringy chips or abrasive dust. This efficient debris removal prevents heat accumulation, thereby protecting the carbide inserts from thermal shock and premature wear. The body geometry is robust, minimizing vibration and chatter, which ensures hole accuracy and superior surface finish. This stability is particularly advantageous when drilling on curved or irregular surfaces, where maintaining concentricity can be challenging. By allowing for higher feed rates and rotational speeds, the 05D313 not only extends tool life but also lowers the total cost per hole.

For MRO professionals and fabrication managers, integrating Walter's Carbide Core Cut series into the tooling inventory translates to reduced downtime associated with tool changes and sharpened efficiency. Whether utilized in a workshop setting or on-site with portable magnetic drilling units, this cutter provides the reliability required for critical infrastructure projects, rail maintenance, and heavy machinery repair. It is an essential asset for operations demanding precision, speed, and durability in the toughest drilling conditions.
