The Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide tool designed for precision boring and reliable general turning. It features an 8.1 mm minimum diameter, 15 mm reach, and a left-hand R0.2 nose to fit tight bores and awkward setups. Optimized for two high-performance coating options, BXC TiN for stainless steels at lower speeds and BMK with a sub-micron, triple-coated finish for maximum heat resistance and smooth cutting across a wide range of materials.

• Solid carbide construction for rigidity: Delivers excellent stiffness and wear resistance to maintain hole size and extend tool life in challenging materials, reducing wandering and rework.
• BMK grade with advanced PVD triple coating: Sub-micron BMK grade provides outstanding heat resistance and a smooth cutting action, supporting consistent performance across many materials and longer tool life.
• BXC TiN coating for stainless steels: TiN-coated BXC grade is optimized for low cutting speeds and stainless steels, delivering reliable finishes, reduced wear, and stable performance in ISO P30–P50 / K25–K40 workpieces.

By choosing the Carmex Tiny Tool, you gain a dependable boring bar that reduces downtime, improves surface finish, and delivers repeatable results across materials. The combination of carbide rigidity and protective coatings ensures longer intervals between tool changes, easier setups, and consistent performance for workshops, job shops, and on-site work alike.
