Carmex Carbide Tiny Tool - Full Radius Grooving - MKR - K20 Grade - 6.1mm Minimum Diameter x 2mm Groove Width - 15mm Reach

The Carmex Carbide Tiny Tool is a compact solid carbide bar designed for full-radius grooving and general turning. With a 6.1 mm minimum diameter, a 2 mm groove width, and a 15 mm reach, it delivers precise grooves in tight spaces while maintaining rigidity for repeatable finishes. Built to MKR - K20 grade specifications, it’s ready for demanding setups and real-world shop use.

This tool family offers two specialized coatings to match your application. The BXC grade uses a PVD TiN coating for low cutting speeds and strong performance with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK grade employs a sub-micron carbide with a triple PVD coating for exceptional heat resistance and smooth cutting, making it a versatile choice for general-material use.

• Precise full-radius grooving in tight spaces: The tool’s geometry and 15 mm reach let you create accurate, full-radius grooves in small features without sacrificing rigidity or finish quality.
• Two coating options for adaptable performance: Choose BXC for efficient low-speed cutting on stainless steels, or BMK for high-heat, all-material capability with smoother cuts and longer tool life.
• Rugged carbide for reliable long life: Solid carbide construction maintains groove geometry under load, reduces chatter, and supports consistent results across many jobs and materials.

This combination of compact geometry, grade options, and durable construction helps you complete grooves faster, with cleaner finishes, fewer tool changes, and dependable performance from the first cut to the last.
