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

Smooth, Chatter-Free Countersinking

Upgrade your metalworking toolkit with the Walter 01U006 3/8" Countersink. If you have ever struggled with countersinks that vibrate and leave rough, wavy edges, this is the solution you need. Built with a Variable Pitch (VP) design, this tool is specifically engineered to stop chatter before it starts. The uneven spacing of the flutes prevents the tool from bouncing in the hole, ensuring you get a glass-smooth finish on your first pass. It is the perfect tool for prepping holes for flush-mount screws or simply cleaning up sharp edges after drilling.

Durability is built right in. Made from M2 High-Speed Steel (HSS), this countersink is tough enough to handle daily abuse in the shop. It cuts through mild steel, stainless steel, and aluminum without dulling quickly. The 82-degree angle is standard for most American fasteners, making it a versatile addition to any fabricator's collection. The specialized tip geometry helps the tool center itself, so you don't have to fight to keep it straight.

Whether you are working on a drill press or using a hand drill, the Walter 01U006 delivers consistent results. Its unique surface treatment helps keep the tool cool and prevents material from sticking to the cutting edges. Stop wasting time sanding down rough chamfers and switch to a countersink that cuts clean every time. Ideal for maintenance, repair, and fabrication shops looking for professional-grade cutting tools.
