Carmex Carbide Tiny Tool is a line of solid carbide bars engineered specifically for face grooving. Designed for professionals and hobbyists alike, these tools create full-radius, rounded grooves for reliable sealing surfaces and smooth finished edges. With a right-hand cutting orientation and a compact 5 mm minimum diameter paired with a 1.5 mm groove width, they fit neatly into standard setups and deliver consistent results across a range of materials.
- Full-radius face grooving design: creates precisely rounded grooves for better seal interfaces and smoother surface finishes, reducing post-process finishing work.
- MZR-K20 solid carbide construction: delivers excellent wear resistance and edge retention, helping you achieve longer tool life and fewer tool changes in demanding grooving tasks.
- Right-hand geometry with defined size: engineered for predictable, repeatable cuts at a 5 mm minimum diameter and 1.5 mm groove width, compatible with common tooling and setup workflows.
This tool excels in applications where rounded groove profiles matter, delivering consistent performance that supports faster setup, reduced downtime, and reliable results in precision machining projects.
