05D540 - Walter 3-1/2 Inch Carbide Tipped Annular Cutter 2 Inch Depth

Premium Carbide Drilling Performance for Hard Metals

The Walter 05D540 3-1/2" x 2" Carbide Core Cut Annular Cutter represents the pinnacle of hole-making technology for industrial applications involving difficult-to-machine materials. Unlike traditional High Speed Steel (HSS) cutters, this premium tool utilizes high-grade carbide inserts that maintain their hardness and cutting edge even under the extreme heat generated during heavy-duty drilling. This makes it the tool of choice for fabricating with stainless steel, cast iron, and other abrasive alloys where standard bits often fail or require frequent replacement.

Engineered for precision and efficiency, the Carbide Core Cut series features a sophisticated flute design that maximizes chip evacuation. This is critical when drilling large diameter holes—such as this 3-1/2 inch specification—as efficient chip removal prevents binding and heat buildup, ensuring a smooth, clean cut every time. The cutter is designed to handle higher feed rates and rotational speeds, significantly reducing cycle times in production environments. Whether you are working on flat plates or curved surfaces like pipes and tanks, the robust body design ensures stability and accuracy.

Durability is a core characteristic of the 05D540. The carbide tips are brazed securely to withstand the mechanical stress of drilling through uneven surfaces or overlapping holes. This resilience translates to a lower cost per hole over the lifespan of the tool, as operators spend less time changing out dull bits and more time machining. Compatible with standard magnetic drilling units, this cutter is an essential asset for MRO operations, structural steel fabrication, and heavy equipment manufacturing where reliability is non-negotiable.

Key Technical Benefits:

• Material Versatility: Excellent performance on stainless steel, varying grades of cast iron, and hard aluminum alloys.
• Thermal Stability: Carbide tips resist thermal softening, allowing for dry cutting in some applications (though lubricant is recommended for maximum life).
• Precision: Delivers accurate, burr-free holes that often eliminate the need for reaming or deburring.
