Carmex Carbide Tiny Tool - Full Radius Grooving - MKL - K20 Grade - 4.1mm Minimum Diameter x 1.5mm Groove Width - 10mm Reach (Left Hand)

Carmex Carbide Tiny Tool is a compact, K20-grade solid carbide bar designed specifically for full-radius grooving and precise turning tasks. Its small-diameter profile and 10 mm reach make it ideal for tight pockets and intricate features, delivering reliable grooves with consistent walls. Built for stainless steels and a wide range of materials, it helps you achieve clean, repeatable results on every pass.

Two coating options extend its versatility: the BXC grade with PVD TiN coating delivers efficient performance at lower cutting speeds, making it well-suited for ISO P30-P50 / K25-K40 stainless steels. The BMK grade features an advanced PVD triple coating on a sub-micron substrate, offering exceptional heat resistance and smooth cutting for demanding materials in the ISO K10-K20 range. Together, these coatings maximize tool life and maintain stable finishes across a broad set of applications.

• Full-radius grooving geometry: creates precise, full-radius grooves with clean walls and minimal rubbing, enhancing part fit and surface quality on stainless steels.
• Dual coating performance: choose BXC TiN for efficient cuts at low speeds or BMK with triple coating for high-heat environments and smoother cutting, extending tool life and reducing downtime.
• Compact, tight-access design: 4.1 mm minimum diameter, 1.5 mm groove width, 10 mm reach, left-hand orientation—optimized for tight features and reduced tool changes without sacrificing rigidity.

This tool helps streamline setups, deliver consistent groove geometry, and boost productivity with fewer inserts and less rework, making it a dependable choice for shops, hobbyists, and professionals alike.
