The Carmex Carbide Tiny Tool is a purpose-built face grooving bar designed for precision, reliability, and versatility in metalworking. Part of the Tiny Tools family, this solid carbide option delivers straight grooves with consistent geometry, making it ideal for accurate seating, sealing surfaces, and clean finishing on a range of components. Its 5 mm minimum diameter and 0.75 mm groove width provide a robust, stable cutting platform that fits common CNC and manual setups.

Two high-grade carbide options give you the right balance of performance and durability for different materials and speeds. The BXC grade features a PVD TiN coating optimized for low cutting speeds on stainless steels (ISO P30-P50 / K25-K40), delivering wear resistance and dependable results at economical feeds. The BMK grade is a sub-micron, triple-coated option offering exceptional heat resistance for demanding jobs, along with smooth cutting and broad material compatibility—making it a solid general-purpose choice when you encounter tougher materials or longer runs.

• Straight-groove geometry for precise face cutting: Produces clean, accurate grooves with consistent width, reducing finishing passes and improving seating accuracy in assemblies.
• Two high-performance coating grades for versatility: Choose BXC TiN for stainless steels at low speeds or BMK’s sub-micron, triple-coated construction for superior heat resistance and smooth cutting across a wide material range.
• Optimized size for stability and reliability: 5 mm minimum diameter with a 0.75 mm groove width provides a robust cutting profile that delivers repeatable results in standard tooling setups.

Designed for engineers, machinists, and hobbyists alike, this tool helps you achieve consistent groove quality with fewer passes, less downtime, and longer tool life. Whether you’re tackling stainless alloys or tougher workpiece materials, the Carmex Tiny Tool delivers dependable performance, straightforward setup, and scalable results that fit both premium and budget-conscious workflows.
