The Carmex Carbide Tiny Tool is a precision solid carbide bar designed for full-radius grooving on small-diameter workpieces. Its compact form, 30 mm reach, and left-hand orientation make it a practical choice for tight turning setups where accurate grooves matter. It supports a minimum diameter of 7.1 mm and a groove width of 1 mm, delivering consistent results in constrained spaces.
Designed as a two-grade solution, this tool line pairs BXC and BMK coatings to cover a wide range of materials and speeds. BXC is a PVD TiN-coated grade optimized for low-cutting-speed applications and performs well on stainless steels (ISO P30-P50 / K25-K40). BMK, with a sub-micron structure and triple PVD coating (ISO K10-K20), offers exceptional heat resistance and smooth cutting, while remaining suitable for general-purpose turning across materials.
- Full-radius grooving capability: Creates precise, smooth grooves with a full-radius profile, while also serving as a reliable option for general turning on small-diameter parts.
- Two advanced coating grades for versatility: BXC provides efficient cutting at low speeds on stainless steels; BMK delivers high heat resistance and smooth cutting across a wide material range.
- Left-hand design with 30 mm reach: Specifically configured for left-side operations, the 30 mm reach, 7.1 mm minimum diameter, and 1 mm groove width ensure a proper fit and predictable results in tight setups.
With the Carmex Carbide Tiny Tool, you gain repeatable groove geometry, consistent performance across materials, and a streamlined turning workflow. The carbide construction and targeted coatings are built to endure demanding grooving tasks, helping you finish parts faster with reliable results and fewer tool changes.
