Carmex Carbide Tiny Tool - Boring Bar - MTL - BXC Grade - 5.1mm Minimum Diameter x 30mm Reach x R0.2 (Left Hand) Spot Drills It’s sized for precise controlThe Carmex Carbide Tiny Tool Boring Bar is a compact, solid carbide bar designed for precision boring and general turning tasks, built to perform in tight bores and small diameter workpieces. It comes in two coating grades to tackle different materials and conditionsBXC (PVD TiN) for low speed cuts on stainless steels, and BMK (sub micron grade with triple PVD coating) for high heat resistance and smooth cutting. Key specs include a 5. 1 mm minimum
