Carmex Carbide Tiny Tool - Boring Bar - MTL - TNX Grade - 6.1mm Minimum Diameter x 30mm Reach x R0.2 (Left Hand)

The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar engineered for precision in small-diameter bores and light turning work. With a 6.1 mm minimum diameter, 30 mm reach, and a left-hand orientation with an R0.2 corner radius, it delivers steady performance in tight spaces and on challenging materials. This tool is suitable for engineers, machinists, and hobbyists who need reliable boring capability without sacrificing accessibility or setup speed.

Two coating options in Carmex’s carbide bar lineup help you tailor performance to the job. The BXC TiN-coated grade is optimized for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40), reducing wear and helping maintain a consistent finish. The BMK sub-micron grade features an advanced triple PVD coating, offering exceptional heat resistance and smooth cutting for demanding materials. Both are designed to maximize tool life and provide dependable results in boring and general turning applications.

• Rigid solid-carbide construction for steady, accurate boring: High stiffness and heat tolerance minimize deflection, helping you maintain precise bore sizes and smooth hole finishes across passes.
• Coatings tuned for performance and versatility: TiN-coated BXC excels at low-speed cutting on stainless steels, while BMK’s triple PVD coating delivers heat resistance and smooth cutting for tougher materials.
• Compact geometry for tight bores: 6.1 mm minimum diameter, 30 mm reach, and R0.2 corner radius in a left-hand configuration ensure stable engagement, controlled chip formation, and predictable wear in restricted spaces.

This boring bar supports a reliable, efficient workflow by delivering repeatable dimensions, reduced downtime for tool changes, and consistent surface finish across a range of materials. It’s a practical, trustworthy choice for precision jobs where compact tooling and dependable performance matter, helping you achieve higher-quality results with greater confidence.
