05F243 - Walter 43mm Carbide Tipped Annular Cutter 55mm Depth

High-Performance Drilling for Tough Industrial Materials

The Walter 05F243 Carbide Core Cut Annular Cutter is a premier tooling solution designed to meet the rigorous demands of modern industrial maintenance and fabrication. Measuring 43mm in diameter with a substantial 55mm depth of cut, this cutter is engineered to overcome the limitations of traditional High-Speed Steel (HSS) bits. In heavy-duty MRO environments where downtime equates to lost revenue, the efficiency of your cutting tools is paramount. This Walter cutter utilizes high-grade tungsten carbide inserts, which provide exceptional hardness and heat resistance. This allows operators to drill through challenging materials—such as stainless steel, cast iron, and abrasive alloys—at significantly higher speeds and feed rates without compromising the tool's integrity.

One of the standout features of the Walter Carbide Core Cut series is its sophisticated body and flute design. The geometry is optimized to clear chips rapidly, preventing clogging and heat accumulation that often lead to premature tool failure. This is particularly critical when drilling deep holes or working with materials that produce long, stringy chips. The result is a cleaner, burr-free hole that requires little to no secondary finishing, streamlining your production process. Furthermore, the carbide tips are robust enough to handle interrupted cuts and uneven surfaces, making this tool versatile enough for on-site repairs where conditions are rarely perfect.

Durability is at the core of the 05F243's design. While HSS cutters may struggle and dull quickly against hard metals, Walter's carbide technology maintains its cutting edge for much longer, delivering a lower cost per hole over the lifespan of the tool. Whether you are drilling into structural steel beams, repairing heavy machinery, or fabricating custom components from hard alloys, this annular cutter provides the reliability and precision required for professional results. It is compatible with a wide range of magnetic drilling units, ensuring seamless integration into your existing equipment lineup.

Key Industrial Benefits

• Extended Tool Life: Carbide inserts outlast HSS in abrasive and hard materials.
• Increased Productivity: Faster penetration rates reduce cycle times on repetitive drilling tasks.
• Versatile Application: Effective on stainless steel, cast iron, and uneven surfaces.
