Description
The Carmex Carbide Tiny Tool – Boring Bar (MTR, BXC Grade) is a compact solid carbide tool designed for internal boring and precision turning. With a minimum diameter of 3.1 mm, a reach of 15 mm, and a nose radius of R0.05, it fits into tight bores and delivers accurate, clean cuts. It offers two coating options for versatility: BXC TiN for low-speed cutting on stainless steels and BMK, a sub-micron grade with a triple PVD coating for high heat resistance and smooth cutting across a broad range of materials.
- Two coating grades for versatile cutting: BXC TiN coating provides reliable performance at low cutting speeds on stainless steels (ISO P30-P50 / K25-K40), while BMK’s sub-micron grade with advanced PVD triple coating delivers exceptional heat resistance and smooth cutting across a wide range of materials (ISO K10-K20).
- Ultra-compact boring bar with precise reach: 3.1 mm minimum diameter, 15 mm reach, and R0.05 nose radius enable accurate internal boring in tight spaces and precise finishing.
- Solid carbide durability for reliable performance: Built as a solid carbide bar, designed for long tool life and consistent results in boring and general turning across materials.
Designed to streamline precision machining, the Tiny Tool offers reliable, repeatable performance across materials, reduces tool changes, and helps achieve smooth surfaces on small-diameter parts. The dual-grade options let you optimize for material and speed, delivering dependable results across stainless steels and a broad range of metals.
