Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for tight bores and small-diameter turning. It’s built for engineers, machinists, and hobbyists who need precise bore geometry in a variety of materials, with a robust carbide body that stands up to demanding shop conditions.

This tool is available in MTR - TNX Grade with two coating options to match your material and speed: BXC, a PVD TiN-coated grade optimized for low cutting speeds and broad stainless-steel compatibility (ISO P30-P50 / K25-K40); and BMK, a sub-micron grade with advanced PVD triple coating for exceptional heat resistance and a smooth, steady cut. Its compact 7.1 mm minimum diameter, 22 mm reach, and R0.2 corner radius make it suitable for confined bores and light turning tasks.

• Two coating grades for versatile material compatibility: BXC (PVD TiN) excels at low cutting speeds and stainless steels (ISO P30-P50 / K25-K40), while BMK (sub-micron with triple PVD) delivers high heat resistance and smoother cutting across a wide material range.
• Precise, small-diameter boring capability: Designed for tight bores with a 7.1 mm minimum diameter, 22 mm reach, and a 0.2 mm corner radius (R0.2) for clean, accurate finishes in confined spaces.
• Durable carbide construction for reliable life: Solid carbide body and coated surfaces provide long tool life and consistent results in demanding applications.

With its compact form, dual coating options, and proven carbide durability, the Carmex Tiny Tool helps you achieve precise bores, smooth finishes, and dependable results across a range of materials. It supports efficient setups and predictable outcomes for both shop environments and in-house manufacturing.
