05F147 - Walter 47mm Carbide Tipped Annular Cutter - 30mm Depth

Precision Drilling for Hardened Materials

The Walter 05F147 Carbide Core Cut is a high-performance annular cutter designed to meet the rigorous demands of modern industrial fabrication. With a diameter of 47mm and a cutting depth of 30mm, this tool is engineered to excel where traditional High-Speed Steel (HSS) cutters fail. The integration of extra-hard carbide inserts allows this cutter to penetrate tough, abrasive materials such as stainless steel, cast iron, and complex alloys with exceptional speed and precision.

One of the primary technical benefits of the Carbide Core Cut series is its ability to maintain structural integrity and cutting edge hardness under high thermal loads. This thermal stability enables operators to run magnetic drilling units at higher RPMs and feed rates, significantly reducing cycle times for large-diameter hole creation. The advanced flute design aids in rapid chip evacuation, preventing heat buildup and binding, which is critical when drilling deep holes in work-hardening materials like austenitic stainless steel.

Furthermore, the annular cutting action removes material only at the periphery of the hole, ejecting a solid slug. This method requires considerably less horsepower and thrust compared to solid twist drilling, reducing wear on the drilling equipment and fatigue for the operator. For MRO professionals and fabrication shops dealing with uneven surfaces or heavy-duty repairs, the Walter 05F147 provides a reliable, long-lasting solution that ensures dimensional accuracy and superior surface finish.
