Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade - 1mm Minimum Diameter x 6mm Reach x R0.05 (Left Hand)

Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision in tight spaces. With a 1 mm minimum diameter, 6 mm reach, and a left-hand cutting geometry, it’s ideal for small-diameter bores and delicate turning tasks where finish and accuracy matter. This tool line also offers two high-performance grades to match your material and speed conditions: BXC, a TiN-coated grade optimized for low cutting speeds on stainless steels, and BMK, a sub-micron grade with a advanced PVD triple coating for maximum heat resistance and smooth cutting across a wide range of materials.

• Compact miniature boring capability: Designed for tight bores and short-reach work, the 1 mm minimum diameter and 6 mm reach let you access confined features with consistent, clean results. The left-hand geometry further supports precise engagement in specialized setups.
• Two premium carbide grades for versatility: BXC provides reliable performance at low cutting speeds on stainless steels (ISO P30-P50 / K25-K40) with a TiN coating, while BMK delivers sub-micron precision with triple PVD coating for exceptional heat resistance and smooth cutting across a broad material range.
• Left-hand cutting with a precise R0.05 radius: The defined R0.05 corner radius and left-hand orientation help achieve stable cuts, reduced chatter, and tighter bore finishes in compact tooling arrangements.

This tiny tool combines engineered geometry with advanced coatings to deliver repeatable bore quality, longer tool life, and quicker setups across a spectrum of materials. Whether you’re manufacturing small components, repairing tight cavities, or prototyping precision parts, this tool supports reliable performance, consistent finishes, and efficient workflow in both boring and general turning applications.
