Carmex Carbide Tiny Tool is a compact, solid carbide bar designed for full-radius grooving and general turning. It’s ideal for machinists, engineers, and hobbyists who need precise grooves in tight spaces, delivering reliable performance across a range of stainless steels.
With MKL geometry and a 7.1 mm minimum diameter, 1.5 mm groove width, and 22 mm reach (left-hand), this tool is built to handle demanding grooving tasks. It’s available in coated grades to suit different cutting conditions: BXC (PVD TiN coated) for low cutting speeds on stainless steels (ISO P30-P50 / K25-K40) and BMK (sub-micron grade with advanced PVD triple coating) for extremely high heat resistance and smooth cutting (ISO K10-K20).
- Full-radius grooving capability: Delivers clean, consistent full-radius grooves with stable cutting in confined spaces, reducing secondary passes and improving surface finish.
- Coated carbide versatility for varying speeds and materials: Choose BXC TiN for dependable performance at lower speeds on stainless steels, or BMK’s sub-micron, triple-coated design for high-heat applications and smoother cutting across a wider material range (ISO P30-P50 / K25-K40 and ISO K10-K20).
- Compact geometry with long reach: 7.1 mm minimum diameter, 1.5 mm groove width, and 22 mm reach in a left-hand configuration to access tight grooves and features while maintaining rigidity and predictable cutting.
In use, the Carmex Tiny Tool provides consistent results, minimizes downtime, and extends tool life thanks to carbide strength and coated reliability. The combination of full-radius capability, material-ready coatings, and a compact, long-reach design makes it a dependable choice for turning and grooving tasks in stainless steels and beyond, helping you finish parts to spec with confidence.
