Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade - 2.5mm Minimum Diameter x 10mm Reach x R0.1 (Left Hand) is a compact, solid carbide bar designed for precise internal boring and small-diameter turning. Its rigid carbide core and slim profile help you achieve clean, accurate holes in tight spaces, making it an ideal choice for engineers, technicians, and hobbyists who demand dependable bore quality. While primarily built for boring, it also handles general turning tasks when space is limited, giving you a versatile tool for multiple workflows.

• Coating options optimized for stainless steels: Two coated grades—BXC with PVD TiN for low cutting speeds and broad stainless-steel compatibility, and BMK with a sub-micron, triple PVD coating for superior heat resistance—provide wear protection and smooth cutting across a wide range of materials.
• Precisely sized for small bores: With a 2.5 mm minimum diameter, 10 mm reach, and left-hand geometry (R0.1 nose radius), this tiny tool reaches tight internal features while maintaining consistent hole geometry and chip control.
• Solid carbide durability for long tool life: The carbide core delivers stiffness and wear resistance, ensuring reliable performance, steady finishes, and reduced downtime even under demanding materials and cutting conditions.

This tiny boring bar supports efficient, high-precision machining by delivering reliable results in confined spaces, reducing tool changes, and extending tool life through advanced coating technology. It’s a practical, confidence-inspiring choice for production runs, prototypes, and mixed-material projects where precision and consistency matter most.
