01U408 - Walter 1-1/2 Inch 82-Degree HSS Countersink with Weldon Shank

Heavy-Duty 1-1/2" Countersink for Metal Fabrication

Upgrade your hole-finishing capabilities with the Walter 01U408 Weldon Shank Countersink. Designed for professional welders and machinists, this 1-1/2 inch tool is built to deliver consistent, chatter-free results in the most demanding shop environments. Whether you are prepping a surface for flush-mount hardware or deburring holes in thick plate steel, this countersink provides the reliability and precision required for top-tier metalworking.

Superior Material and Geometry

At the core of this tool is high-quality M2 HSS (High-Speed Steel). Unlike standard carbon steel bits, M2 HSS retains its hardness at elevated temperatures, making it the ideal choice for cutting through stainless steel, mild steel, and non-ferrous metals like aluminum. The 82-degree tip geometry is precision-ground to match standard countersunk screw heads, ensuring a tight and flush fit every time. This attention to detail reduces assembly issues and enhances the aesthetic quality of your finished projects.

Engineered for Stability

Slippage is a major frustration when using large diameter cutting tools. The Walter 01U408 solves this with its industry-standard Weldon shank. Designed to fit securely into magnetic drilling units and other compatible holders, the shank's flat section provides a solid contact point for set screws. This prevents the tool from rotating inside the chuck, allowing you to apply the necessary feed pressure without fear of stalling or slipping.

Smooth, Chatter-Free Performance

Achieving a smooth finish is critical, and the Walter countersink excels thanks to its variable pitch flute design. This engineering choice effectively breaks up the rhythmic vibrations that typically cause "chatter" or ripple marks on the cut surface. The result is a clean, smooth bevel that requires little to no secondary finishing. Combined with a specialized surface coating that minimizes friction, this tool cuts cooler and lasts longer, providing excellent value for your workshop.
