Carmex Carbide Tiny Tool - Boring Bar - MTL - BXC Grade - 3.7mm Minimum Diameter x 15mm Reach x R0.1 (Left Hand)

Meet the Carmex Carbide Tiny Tool Boring Bar—an ultra-compact, solid carbide bar designed for precision boring and reliable general turning in small-diameter work. With a 3.7 mm minimum diameter, 15 mm reach, and a left-hand R0.1 corner, it delivers clean, accurate holes in tight spaces while maintaining solid rigidity through demanding cuts.

This tool is available in two high-performance carbide grades, each paired with protective PVD coatings to match your material and cutting conditions. The BXC grade uses TiN coating for improved life at lower cutting speeds and works well on stainless steels (ISO P30-P50 / K25-K40). The BMK grade features a sub-micron core with a triple PVD coating for exceptional heat resistance and smooth cutting, making it a versatile choice for all materials.

• Tiny, precise geometry for tight bores: 3.7 mm minimum diameter, 15 mm reach, and a left-hand R0.1 corner deliver accurate hole size and a high-quality surface finish in confined spaces.
• Two high-performance carbide grades: Choose BXC for stainless steels at low speeds with extended life, or BMK for maximum heat resistance and smooth cutting across a wide range of materials.
• Coating-enhanced durability: PVD coatings reduce wear and stabilize cutting performance, helping you achieve consistent results over more cycles with less maintenance.

Designed to simplify boring and turning workflows, this tiny carbide bar provides dependable, repeatable results from setup through finish. Its robust carbide core and specialized coatings help you maintain tight tolerances, reduce downtime, and finish surfaces cleanly—so you can complete jobs faster and with greater confidence.
