Carmex Carbide Tiny Tool is a compact solid carbide grooving bar designed for full-radius grooves on small-diameter workpieces and general turning. Its precise geometry ensures clean, repeatable grooves with minimal finishing passes, helping you complete tight tasks quickly and accurately.

Part of the MKL lineup, it’s offered in two high-performance grades to match your material and speed: BXC, a PVD TiN-coated grade for lower cutting speeds on stainless steels, and BMK, a sub-micron grade with advanced PVD triple coating for exceptional heat resistance and smooth cutting across materials. This variant features a 6.1 mm minimum diameter, 1 mm groove width, and a 15 mm reach in a left-hand configuration.

• Full-radius groove geometry: Delivers consistent, accurate grooves on small-diameter parts, reducing polishing or finishing passes and improving overall surface quality.
• Two high-performance coating grades: BXC (TiN) extends tool life at low speeds on stainless steels, while BMK’s triple coating provides superior heat resistance for smoother cutting across a wide material range.
• Compact MKL design with precise dimensions: 6.1 mm minimum diameter, 1 mm groove width, and 15 mm reach in a left-hand orientation to access tight pockets and position grooves exactly where you need them.

This tiny carbide tool streamlines your grooving workflow by combining a compact form with durable coatings and precise geometry. It delivers repeatable, clean grooves quickly, reduces tool changes, and performs reliably across materials from stainless steels to general turning. Whether you’re machining small components, fixtures, or prototypes, this tool helps you achieve consistent results, superior finish, and improved production efficiency.
