Carmex Carbide Tiny Tool - Boring Bar - MTR - BMK Grade - 2.1mm Minimum Diameter x 10mm Reach x R0.05

The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision in tight bores and small-diameter turning. With a minimum diameter of 2.1 mm and a reach of 10 mm, it reaches into narrow features while delivering stable cutting and repeatable results. The nose radius, R0.05, supports smooth entry and a clean finish on delicate parts.

This tool family offers coating options to match your material and speed. The BXC grade uses a PVD TiN coating for low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK grade employs a sub-micron core with a triple PVD coating for exceptional heat resistance and smooth cutting, providing general-purpose performance across materials.

• Compact, 2.1 mm diameter with 10 mm reach: Access tight bores and small features with consistent depth control and stable cutting in confined spaces.
• Coating options for versatile cutting: BXC TiN coating for low-speed stainless work and BMK triple PVD coating for high-heat, all-material performance.
• R0.05 nose radius for smooth finishes: Enables gentle entry and minimizes chatter, helping achieve clean, precise surface quality on delicate features.

Whether you’re an engineer, machinist, buyer, tradesperson, or hobbyist, this tiny carbide boring bar delivers reliable, repeatable results in tight spaces. The blend of a rigid carbide core and purpose-built coatings extends tool life, reduces downtime, and supports consistent finishes across a range of materials and applications.
