05D548 - Walter 4-Inch Carbide Tipped Annular Cutter - 2-Inch Depth

Precision Engineering for Tough Alloys

The Walter 05D548 Carbide Core Cut annular cutter represents the pinnacle of hole-making technology for heavy industrial applications. Engineered specifically for materials that pose significant challenges to traditional High-Speed Steel (HSS) tooling, this 4-inch diameter cutter utilizes premium tungsten carbide tips. These inserts are brazed onto a specialized alloy body, providing the extreme hardness required to penetrate stainless steel, cast iron, and other high-tensile alloys without losing the cutting edge. The carbide composition ensures that the cutter retains its hardness even under the high thermal loads generated during large-diameter drilling operations.

One of the critical design features of the Carbide Core Cut series is its advanced flute geometry. When drilling a 4-inch hole, chip evacuation is paramount to preventing binding and heat accumulation. Walter has designed these cutters with wide, polished flutes that efficiently channel swarf away from the cutting zone. This not only extends the life of the tool but also ensures a superior surface finish on the hole wall, often eliminating the need for secondary reaming or deburring operations. The 2-inch depth of cut capacity makes this tool versatile for structural steel fabrication, heavy equipment repair, and pipeline work.

Furthermore, the structural integrity of the cutter body is designed to withstand the torque and radial forces inherent in large-diameter drilling. By focusing the cutting force on a narrow perimeter, the annular cutter requires significantly less energy than a twist drill of equivalent size. This efficiency reduces wear on the magnetic drilling unit's motor and gearbox. For fabrication shops dealing with abrasive materials or requiring consistent, precise holes in thick plate, the Walter Carbide Core Cut offers a reliable, high-performance solution that maximizes productivity and minimizes downtime associated with tool changes.
