Carmex Carbide Tiny Tool - Boring Bar - MTL - BXC Grade - 4.1mm Minimum Diameter x 22mm Reach x R0.2 (Left Hand)

The Carmex Carbide Tiny Tool is a compact boring bar designed for precise boring and light turning in tight spaces. Made from solid carbide, it delivers dependable performance across a range of materials, making it suitable for engineers, technicians, hobbyists, and maintenance professionals. With a 4.1 mm minimum diameter, 22 mm reach, and a left-hand R0.2 nose radius, it’s built to access tight bores while delivering smooth, accurate finishes.

This tool is ideal for those who need reliable performance in stainless steels and other materials without switching to larger tooling. It’s engineered to pair with Carmex’s coated carbide grades for enhanced wear resistance and consistent results in demanding applications.

• Compact boring capability: Access tight bores with a 4.1 mm minimum diameter and 22 mm reach, delivering accurate holes with minimal tool deflection.
• Left-hand geometry with precise nose radius: Designed for left-handed cutting and deep bore operations, promoting reliable chip flow and smooth finishes at the R0.2 nose radius.
• Coated carbide for durability and versatility: BXC Grade with PVD TiN coating supports low cutting speeds and stainless steels (ISO P30-P50 / K25-K40); BMK Grade with sub-micron, triple PVD coating offers exceptional heat resistance for high-load turning across materials.

With this tiny carbide boring bar, you can shorten cycles, reduce tool changes, and achieve consistent hole quality across a range of materials. The robust carbide body resists wear in demanding environments, while coatings help maintain sharpness at lower cutting speeds or under high-heat conditions. It enables more efficient setups, fewer reworks, and steady, repeatable results in both production and repair work.
