Scientific Cutting Tools GT061-4A Groove Tool

Scientific Cutting Tools GT061-4A Groove Tool is a solid carbide retaining-ring groove tool finished with an AlTiN coating for enhanced wear resistance in tight internal bores. It features a 1/8" (0.125") shank, a groove width of 0.0620", and a minimum bore diameter of 0.120" for precise, repeatable groove formation; the maximum groove depth is 0.250" with an offset of 0.040" and an overall length of 1.50" that suits compact machine tool setups. The GT061-4A designation identifies the AlTiN-coated variant of the GT061-4 family, delivering improved edge life under demanding cutting conditions while maintaining strict dimensional control on groove width and depth. Constructed from premium submicron carbide, this tool is purpose-built for retaining-ring groove operations in small-diameter components such as shafts, gears, and housings, ensuring a clean pocket for snap rings without compromising bore integrity.
