Carmex Carbide Tiny Tool - Full Radius Grooving - MKR - BXC Grade - 7.1mm Minimum Diameter x 1.5mm Groove Width - 22mm Reach

The Carmex Carbide Tiny Tool – Full Radius Grooving (MKR) is a compact, solid carbide bar designed to handle full-radius grooving applications. It also delivers reliable general turning performance. With a 7.1 mm minimum diameter, a 1.5 mm groove width, and a 22 mm reach, it enables clean, precise grooves in tight pockets and hard-to-reach features.

This tool line offers two coated grades to match your materials and speeds. BXC is a PVD TiN-coated grade optimized for low cutting speeds and a broad range of stainless steels (ISO P30-P50 / K25-K40). BMK uses a sub-micron substrate with an advanced PVD triple coating for extremely high heat resistance and smooth cutting, delivering strong general-purpose performance across materials.

• Full-radius grooving capability: Delivers precise, uniform grooves with a reliable radius, reducing finishing steps and ensuring consistent fits in assemblies.
• Coated carbide grades for versatile material coverage: BXC excels at stainless steels at low speeds, while BMK provides high heat resistance and smooth cutting across a wide range of materials.
• Compact reach and robust geometry: 22 mm reach in a small, rigid body supports access to tight features while maintaining edge stability for long tool life.

Using the Carmex Tiny Tool helps you achieve predictable groove geometry, reduce downtime, and improve throughput across turning and grooving operations. Its carbide core and specialized coatings are built to endure demanding shop environments, delivering reliable performance and consistent results just when you need them.
