05H011 - Walter 11/16 Inch Carbide Core Cut Annular Cutter with Universal Shank

High-Performance Carbide Drilling for Tough Alloys

The Walter 11/16" x 1" Carbide Core Cut Annular Cutter is an industrial-grade tool engineered to solve the challenges of drilling hard, abrasive, and uneven materials. Unlike traditional High-Speed Steel (HSS) cutters that can dull quickly or overheat when facing resistant metals, this carbide-tipped cutter is built to maintain its cutting edge through the most demanding applications. It is specifically designed to excel in materials such as stainless steel, cast iron, tough alloys, and composites, making it an indispensable asset for precision metalworking and heavy fabrication environments.

At the heart of its performance is a sophisticated flute and body design that maximizes chip evacuation. Efficient chip removal is critical when drilling deep holes or working with materials that produce long, stringy swarf; this design prevents clogging and reduces heat buildup, ensuring a cleaner cut and longer tool life. The cutter features a universal shank, ensuring broad compatibility with a wide range of magnetic drilling units available on the market. This versatility allows operators to swap tools quickly without worrying about fitment issues, streamlining workflow on the shop floor or job site.

One of the standout capabilities of the Walter Carbide Core Cut series is its ability to handle uneven and curved surfaces. Standard twist drills often wander or break when engaging non-flat surfaces, but the geometry of this annular cutter ensures stable, accurate penetration from the moment of contact. This precision allows for faster feed rates and reduced operator fatigue, as the tool does the work with minimal downward pressure required. Whether you are drilling structural steel rails, performing on-site repairs, or fabricating custom components from hard alloys, this cutter delivers consistent, burr-free holes with exceptional surface finish.

By investing in carbide technology, users benefit from significantly increased productivity. The ability to drill at higher speeds without sacrificing tool life translates to lower cost-per-hole and less downtime for tool changes. The 05H011 model provides an 11/16-inch diameter hole with a 1-inch depth capacity, a common size for bolt holes and structural connections. It represents the ultimate choice for professionals who demand reliability and efficiency in their metal drilling operations.
