Carmex Carbide Tiny Tool is a compact solid carbide bar engineered for full-radius grooving on small-diameter workpieces. With a 6.1 mm minimum diameter and a 1 mm groove width, it delivers precise, consistent grooves in tight spaces, while its 15 mm reach and left-hand orientation expand setup options for turning operations.

This tool is offered in two TNX-grade coatings to match different materials and cutting conditions. BXC is a PVD TiN-coated grade optimized for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40). BMK uses a sub-micron structure with triple PVD coatings (ISO K10-K20) for excellent heat resistance and smooth cutting across materials, making it a versatile choice for general-purpose grooving and turning.

• Two TNX-grade coating options: BXC (PVD TiN) for low-speed stainless-steel work and BMK (sub-micron, triple-coated) for high-heat and broad-material performance, delivering durable edge wear resistance across jobs.
• Full-radius grooving in a compact form: 6.1 mm minimum diameter and 1 mm groove width enable precise full-radius grooves on small parts while maintaining a strong, chip-friendly edge.
• Left-hand, 15 mm reach for flexible setups: The left-hand orientation and 15 mm reach provide access to tight features and awkward geometries without repositioning the workpiece, improving setup speed and process stability.

By combining dedicated full-radius grooving capability with TNX-grade coatings and a robust carbide body, this Carmex Tiny Tool helps you complete precise grooves faster, extend tool life, and reduce downtime. Its optimized edge geometry and coatings reduce heat buildup, while the small-diameter, long-reach design improves throughput on complex parts—delivering reliable, versatile grooving and turning performance for engineers, machinists, and hobbyists alike.
