The Carmex Carbide Tiny Tool Boring Bar (MTL) in BXC Grade is a compact, high-precision solution for tight bores and light turning jobs. With a 3.7 mm minimum diameter, 10 mm reach, and a left-hand nose radius of R0.1, it fits into narrow cavities and delivers reliable, consistent cutting performance.

Built for stainless steels and versatility across materials, this BXC-grade tool uses a PVD TiN coating to optimize wear resistance at low cutting speeds, helping you achieve steady feeds, clean finishes, and longer tool life in demanding machining tasks.

• Small-diameter, 10 mm reach: Access tight bores and deep pockets with a single tool, reducing tool changes and streamlining setup.
• Left-hand geometry with R0.1 nose radius: Delivers stable cutting and clean finishes in left-handed boring operations, minimizing chatter and deflection.
• PVD TiN-coated BXC grade for wear resistance: Optimized for low cutting speeds and stainless steels, delivering longer tool life and more consistent results.

This tiny carbide bar helps you complete precise bores faster, with fewer tool changes and smoother finishes across materials. Its robust carbide core and TiN coating support dependable performance at the speeds typical for small-diameter boring, so you can rely on consistent results from roughing to finishing passes.
