Uxcell 3.9mm HSS Cobalt Chucking Reamer - Straight Flute Metal Cutting Tool For Lathe & Drill Press

Hey machinists! This uxcell chucking reamer is exactly what you need for getting those holes perfectly sized and smooth. Made from high-speed steel with cobalt, it's seriously tough—hard, wear-resistant, and built to handle stainless steel, alloy steel, cast iron, copper, and other metals without chipping or dulling too fast. The 3.9mm cutting diameter is spot-on for semi-finish and finish work, and with 6 straight flutes, it gives you a clean, accurate cut every time. Overall length is 75mm with an 18mm flute, so it fits nicely in most chucks and collets. Use it on your lathe, drill press, or even by hand if you're careful. Great for hitting tight tolerances (like IT8 or better) and improving surface finish. If you're tired of rough, out-of-spec holes, grab this reamer—it’s a workshop essential that makes precision work way easier.
