01U012 - Walter 3/4-Inch 82-Degree VP High-Speed Steel Countersink

Precision Engineering for Chatter-Free Finishes

The Walter 01U012 3/4" Variable Pitch Countersink represents a significant advancement in hole preparation technology. Engineered for professionals who demand exact tolerances and superior surface finishes, this tool addresses the common issues associated with traditional countersinking, such as chatter and uneven surfaces. At the core of its performance is the innovative variable pitch geometry. By irregularly spacing the cutting flutes, the tool disrupts the harmonic vibrations that typically cause chatter, ensuring a smooth, clean cut every time.

Material selection is critical for industrial cutting tools, and this countersink is crafted from premium M2 High-Speed Steel (HSS). This material provides the necessary hardness and heat resistance to maintain a sharp cutting edge even under the thermal stress of machining tough alloys. The tool features a standard 82-degree point angle, making it universally compatible with the vast majority of flat-head fasteners used in mechanical assemblies. Furthermore, a specialized surface treatment is applied to the tool to reduce friction and improve chip evacuation, preventing clogging and heat buildup.

Versatility is another hallmark of the Walter VP Countersink. While it excels at creating countersunk holes for fasteners, its robust design makes it equally effective for general deburring and chamfering tasks. Whether you are working with mild steel, challenging stainless steel, or softer non-ferrous metals like aluminum and brass, this tool delivers consistent results. The precise tip geometry ensures self-centering capability, allowing for accurate engagement with the workpiece without wandering.
