Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for small-diameter boring and general turning tasks. With a 4.1 mm minimum diameter, a 15 mm reach, and a precise R0.1 nose radius, it delivers accurate, repeatable cuts in tight bores and pockets.
Designed for engineers, machinists, and hobbyists alike, this tiny tool provides versatility across materials and applications. It comes in two high-performance coating grades that optimize performance at different speeds: the BXC Grade with PVD TiN for low-speed cutting of stainless steels, and the BMK Grade, a sub-micron option with a triple PVD coating for excellent heat resistance and smooth cutting across a wide range of materials.
- Small-diameter bore capability: 4.1 mm minimum diameter, 15 mm reach, and R0.1 nose radius enable precise boring and turning in tight spots with clean, accurate finishes.
- Coating options for versatility: BXC TiN coating improves wear resistance and consistency at low cutting speeds on stainless steels (ISO P30-P50 / K25-K40).
- High-heat BMK performance: BMK sub-micron grade with triple PVD coating delivers exceptional heat resistance and smooth cutting across various materials, helping extend tool life and maintain stable cuts.
This combination of compact geometry, dual coating options, and hard-wearing carbide delivers reliable performance, reduces downtime, and helps you achieve precise, repeatable results in every boring or turning task.
