01U500 - Walter 2-Inch M2 HSS Countersink with Weldon Shank

Precision Countersinking with Walter M2 HSS Technology

The Walter 01U500 is a high-performance 2-inch countersink designed to meet the rigorous demands of modern metal fabrication and industrial maintenance. Crafted from premium M2 High-Speed Steel (HSS), this tool is engineered to withstand high temperatures and abrasive wear, making it an excellent choice for processing tough materials such as stainless steel, mild steel, and various non-ferrous alloys. The tool features a standard 82° point angle, which is the industry norm for seating flat-head screws and fasteners flush with the workpiece surface, ensuring a professional and clean finish every time.

One of the defining characteristics of this Walter countersink is its specialized geometry. It incorporates a variable pitch design that disrupts the harmonic vibrations typically generated during cutting. This innovation drastically reduces chatter, a common problem that can ruin surface finishes and reduce tool life. By ensuring a smooth cutting action, the 01U500 delivers a mirror-like finish on chamfers and deburred edges, reducing the need for secondary finishing operations. The unique tip geometry further aids in centering the tool and initiating the cut effortlessly, requiring less feed pressure from the operator.

Reliability is key in heavy-duty applications, and the inclusion of a Weldon shank on this 2-inch tool ensures maximum stability. The flat surface of the Weldon shank allows the set screw in the tool holder to lock the bit firmly in place, preventing rotation or slippage under high-torque conditions. This is particularly important when working with a large diameter tool like this 2-inch countersink, where the cutting forces are significant. Whether used in a magnetic drill press, a radial arm drill, or a stationary milling machine, the Walter 01U500 provides the secure grip and consistent performance professionals rely on.

In addition to its structural benefits, the tool undergoes a special surface treatment that enhances chip flow and reduces friction. This treatment helps keep the cutting edge cooler for longer periods, further extending the service life of the countersink. For fabricators looking to optimize their hole preparation processes—whether for structural steel, machinery assembly, or general metalworking—the Walter 01U500 offers a blend of durability, precision, and efficiency that is hard to beat.
