05F245 - Walter 45mm TCT Annular Cutter 55mm Depth

Precision Engineering for Tough Industrial Drilling

The Walter 05F245 Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for heavy industrial applications. Designed specifically to address the challenges of drilling through high-tensile materials, this 45mm diameter cutter features premium tungsten carbide tips that significantly outperform traditional High-Speed Steel (HSS) alternatives. In environments where efficiency and precision are paramount, the Carbide Core Cut series delivers by allowing for substantially higher feed rates and rotational speeds, reducing cycle times on large fabrication projects.

One of the critical engineering achievements of this tool is its specialized flute and body geometry. When drilling deep holes—up to the 55mm depth capacity of this unit—chip evacuation becomes a limiting factor. Walter has optimized the spiral design to rapidly eject swarf, preventing heat accumulation that can lead to work-hardening of the material or thermal damage to the cutter. This makes it an exceptional choice for processing stainless steel, cast iron, and other abrasive alloys where thermal management is crucial for tool longevity.

The 05F245 is not merely a drill bit; it is a precision instrument compatible with standard magnetic drilling units. Its robust construction minimizes vibration, ensuring hole accuracy and surface finish quality that often eliminates the need for secondary reaming operations. Whether deployed in a fabrication shop or on a remote job site, this cutter provides the reliability required for structural steel, rail, and heavy equipment maintenance. By concentrating the cutting force on the periphery of the hole, it requires less energy than twist drills, preserving the lifespan of the magnetic drill motor while delivering clean, burr-free holes in the toughest substrates.

Technical Superiority

The inclusion of extra-hard carbide inserts allows this cutter to tackle materials with uneven surfaces or interruptions without the catastrophic failure often seen in brittle tooling. This resilience makes it a strategic investment for MRO operations dealing with diverse and unpredictable material conditions.
