The Carmex Carbide Tiny Tool is a compact solid carbide bar designed for full-radius grooving on small-diameter parts, with the versatility to handle general turning as well. It’s a smart choice for engineers, shops, and hobbyists who need precise grooves in tight spaces without sacrificing reliability.

Available in MKL K20 grade with two high-performance coatings, it offers options tailored to your material and cutting conditions. BXC TiN-coated grade is optimized for low-speed cuts and stainless steels, while BMK uses a sub-micron, triple coating for exceptional heat resistance and smooth cutting across a broad range of materials.

• Full-radius grooving capability: Delivers precise, full-radius grooves on small-diameter workpieces, reducing post-processing and ensuring consistent bottom radii during turning.
• Two coating options for versatile performance: BXC TiN-coated grade excels at low-speed cutting of stainless steels (ISO P30-P50 / K25-K40); BMK's sub-micron, triple coating provides high heat resistance for demanding materials and general-purpose use.
• Compact geometry with left-hand reach: 7.1 mm minimum diameter, 2 mm groove width, and a 22 mm reach in a left-hand configuration—designed for tight radii and standard turning setups.

This tool supports faster, more consistent grooving workflows by combining a robust carbide core with coatings tuned for real-world cutting conditions. Its precise geometry and optimized coatings help maintain sharpness, reduce downtime, and deliver reliable results across common materials, enabling you to finish parts with better surface quality and fewer reworks.
