Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide solution designed for precise internal boring and light turning on small workpieces. With a 5.1 mm minimum diameter, a 15 mm reach, and a left-hand geometry, it reaches tight bores and maintains clean, consistent tool paths. It is part of a versatile line offering two coating grades: BXC, a PVD TiN-coated grade for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40), and BMK, a sub-micron grade with advanced PVD triple coating (ISO K10-K20) for maximum heat resistance and smooth cutting across materials.

• Compact internal-boring geometry: Access tight bores with a 5.1 mm minimum diameter and 15 mm reach, while the left-hand orientation helps with setup and alignment in confined spaces.
• BXC TiN-coated grade for stainless steels: Optimized for low cutting speeds to reduce heat and wear, delivering reliable finishes on stainless steels (ISO P30-P50 / K25-K40).
• BMK sub-micron grade with triple PVD coating: Offers exceptional heat resistance and smoother cutting across a broad range of materials, ensuring consistent performance even in demanding applications.

These capabilities translate into real-world benefits: you can complete precise internal work with less setup time, enjoy longer tool life from reduced heat and wear, and achieve cleaner finishes across a variety of materials. The combination of small size, left-hand geometry, and dual-grade coatings helps you reduce downtime, improve productivity, and deliver repeatable results in boring and general turning tasks.
