The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for precise internal turning in tight spaces. With a compact 6.1 mm minimum diameter, 22 mm reach, and a 0.2 mm nose radius (R0.2), it delivers controlled access to confined features while maintaining rigidity for clean, consistent finishes.

BMK Grade features a sub-micron structure with an advanced PVD triple coating (ISO K10–K20), delivering extremely high heat resistance and smooth cutting for dependable performance across materials.

• Compact 6.1 mm diameter with 22 mm reach: Access tight bores and internal features with precision, while the 0.2 mm nose radius helps produce smooth, accurate surface finishes.
• BMK Grade with PVD triple coating: Sub-micron construction and triple coating provide exceptional heat resistance and consistently clean cuts, even under demanding cutting conditions.
• Versatile for boring and general turning: Primed for tight boring tasks yet capable of general turning, reducing tooling swaps and streamlining your workflow.

This tiny carbide bar helps you complete intricate internal features with fewer passes, tighter tolerances, and reliable finishes. The combination of compact geometry, precise nose radius, and high-heat BMK coating translates to improved workflow, reduced downtime, and stable results across stainless steels and other materials.
