01U006 - Walter 3/8 Inch 82-Degree Variable Pitch Countersink M2 HSS

Precision Countersinking with Walter Technology

The Walter 01U006 is a premium 3/8-inch countersink engineered to deliver superior surface finishes and dimensional accuracy. Manufactured from high-quality M2 High-Speed Steel (HSS), this tool is designed to withstand the rigors of industrial metalworking. The 82-degree point angle is the industry standard for flat-head screws, ensuring a perfect flush fit. What sets this tool apart is its specialized geometry and material composition, which allow it to maintain a sharp cutting edge even when processing tough materials like stainless steel.

A common challenge in countersinking operations is "chatter"—harmonic vibrations that cause a rippled, uneven surface finish. The Walter 01U006 addresses this with its innovative Variable Pitch (VP) design. By varying the spacing between the cutting flutes, the tool disrupts the harmonic resonance that causes chatter. The result is a smooth, clean cut every time, reducing the need for secondary finishing operations. This design also contributes to reduced tool wear, making it a cost-effective choice for high-volume production environments.

Versatility is a core attribute of this countersink. It performs exceptionally well across a wide range of materials, including mild steel, stainless steel, and non-ferrous metals such as aluminum and brass. The tool features a unique surface treatment that aids in chip evacuation and reduces heat generation, further enhancing its durability. Whether utilized for deburring drilled holes or creating precise countersinks for fasteners, the Walter 01U006 offers the reliability and performance demanded by professional machinists.
