05F231 - Walter 31mm Carbide Annular Cutter 55mm Depth

Precision Engineering for Hard Metals

The Walter 31mm x 55mm Carbide Core Cut (SKU: 05F231) represents the pinnacle of annular cutter technology, specifically engineered for industrial applications involving hard and abrasive materials. Unlike traditional High-Speed Steel (HSS) cutters which may struggle or dull quickly on tough alloys, this carbide-tipped tool is designed to maintain its cutting edge under extreme stress. The 31mm diameter and 55mm cutting depth make it an essential tool for structural steel fabrication, heavy machinery maintenance, and large-scale manufacturing where deep, precise holes are required.

Walter's advanced carbide technology allows for significantly higher speed and feed rates, reducing cycle times and increasing overall productivity. The cutter features a sophisticated flute design that efficiently evacuates chips, preventing heat buildup and binding—common issues when drilling deep holes in materials like stainless steel and cast iron. This thermal management is crucial for maintaining the integrity of both the tool and the workpiece, ensuring a clean, burr-free finish that often eliminates the need for secondary reaming or deburring operations.

Durability is a core feature of the 05F231. The extra-hard carbide inserts are brazed to a tough alloy body, providing the rigidity needed to prevent chatter while drilling uneven surfaces or overlapping holes. Whether used in a workshop setting or on-site with a magnetic drilling unit, this cutter delivers consistent, reliable performance. It is the preferred choice for professionals working with challenging substrates such as:

• Stainless Steel (300 and 400 series)
• Cast Iron and Ductile Iron
• High-Tensile Alloys
• Hardened Structural Steel

Invest in the Walter Carbide Core Cut for operations where precision, speed, and tool longevity are non-negotiable.
