Carmex Carbide Tiny Tool - Boring Bar - MTL - BXC Grade - 5.1mm Minimum Diameter x 10mm Reach x R0.2 (Left Hand) is a compact solid carbide boring bar built for precision in tight spaces. With a 5.1 mm minimum diameter, 10 mm reach, and a left-hand R0.2 nose, it is well suited for small-diameter bores and light turning tasks where accuracy and surface finish matter.

This tool family covers two coating grades to suit different materials and speeds. The BXC grade uses a PVD TiN coating designed for lower cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK grade features a sub-micron grade with advanced PVD triple coating, delivering extremely high heat resistance and smooth cutting for general-purpose use across materials.

• Coating versatility for diverse materials: Choose BXC TiN for efficient cutting at lower speeds on stainless steels, or BMK’s triple-coated formulation for high-heat operation and smooth cutting across a broad material range, ensuring reliable performance on varied jobs.
• Micro-bore precision with repeatable geometry: The 5.1 mm minimum diameter, 10 mm reach, and R0.2 nose provide accurate, consistent cuts in tight bores and slim turning applications.
• Durable carbide construction with optimized wear resistance: Solid carbide core paired with advanced coatings delivers long tool life, reduced downtime, and stable cutting under typical production loads.

This tiny boring bar supports precise small-diameter work, helping you achieve consistent finishes, minimize tool changes, and keep workflows moving from prototype to production with dependable performance.
