The Carmex Carbide Tiny Tool (MDL) is a compact carbide cutting tool engineered for small-thread relief, chamfering, and grooving on miniature components. Its precise edge geometry supports clean starts and consistent relief and grooves, making it ideal for tight-tolerance work in electronics, small assemblies, and precision machining.
Built from premium BMK-grade carbide, this tiny tool combines durability with reliable performance. It features a 6.1 mm minimum diameter, a 1.4 mm reach, and a left-hand R0.5 geometry, enabling access to confined areas and producing repeatable results on challenging materials.
- Precision carbide construction: Premium BMK-grade carbide delivers outstanding wear resistance and edge stability, so thread relief, chamfers, and grooves stay crisp over many cycles and through tough materials.
- Left-hand geometry for tight access: The compact 6.1 mm minimum diameter and 1.4 mm reach with left-hand orientation provide control in tight corners, reduce setup time, and improve start-cut accuracy.
- Three-in-one versatility: Specifically designed for small-thread relief, chamfering, and grooving, this tool minimizes tool changes and delivers clean, consistent features on small parts.
With this tiny carbide tool, you’ll experience faster setups, fewer passes, and more consistent results on small components. The robust BMK-grade carbide and focused geometry help reduce downtime, improve surface finish, and support repeatable production quality across parts and materials.
