05D102 - Carbide Tipped Annular Cutter 1-1/8 Inch x 1-1/2 Inch Depth

High-Performance Drilling for Tough Materials

The Walter 05D102 Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for industrial applications involving hard and abrasive materials. Unlike traditional High-Speed Steel (HSS) cutters, this tool utilizes premium carbide inserts that significantly increase hardness and heat resistance. This construction allows the cutter to maintain its cutting edge even when subjected to the high temperatures generated during the drilling of stainless steel, cast iron, and other tough alloys. The 1-1/8 inch diameter and 1.5-inch depth of cut make it a versatile choice for structural steelwork, heavy machinery repair, and fabrication shops requiring precise, large-diameter holes.

Technically, the cutter features an exclusive body and flute design engineered to optimize chip flow. In deep hole drilling, chip evacuation is critical to preventing binding and heat accumulation. The Walter Carbide Core Cut excels in this area, ejecting chips efficiently to allow for continuous drilling without the need for frequent peck cycles. The carbide tips are brazed securely to the body, providing the rigidity necessary to handle uneven surfaces or interrupted cuts without shattering. This stability allows operators to run their magnetic drilling units at higher speeds and feed rates, maximizing productivity while minimizing tool wear.

Furthermore, the core cutting action of this tool requires significantly less horsepower than a solid twist drill of the same diameter. By removing only the periphery of the hole and ejecting a solid slug, the machine converts more energy into cutting action rather than turning the entire volume of metal into chips. This efficiency reduces mechanical stress on the drilling unit and ensures cleaner, burr-free holes with superior surface finish. For MRO professionals and machinists dealing with challenging substrates, the 05D102 offers a reliable, long-life solution that reduces cost-per-hole and downtime associated with tool changes.
