Carmex Carbide Tiny Tool - Boring Bar - MTR - BXC Grade - 5.1mm Minimum Diameter x 30mm Reach x R0.1

The Carmex Carbide Tiny Tool is a solid carbide boring bar built for small-diameter internal work and general turning. With a 5.1 mm minimum diameter, a 30 mm reach, and a precise R0.1 nose radius, it delivers clean, accurate bores in tight spaces while maintaining rigidity and finish quality.

This tool family offers two coating grades to suit different materials and speeds: BXC TiN-coated for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40), and BMK sub-micron grade with a triple PVD coating for high heat resistance and smooth cutting across a broad material range.

• Miniature bore capability with consistent tolerances: The 5.1 mm minimum diameter, 30 mm reach, and R0.1 nose radius enable accurate internal features in tight spaces with predictable, repeatable results.
• Coating options for versatility across materials: Choose BXC TiN for efficient cutting of stainless steels at low speeds, or BMK with triple PVD coating for higher heat tolerance and smooth cutting on a wide range of materials.
• Solid carbide construction for durability and smooth cutting: Rigid carbide construction resists wear and deflection, delivering steady performance in boring and general turning and helping minimize downtime and rework.

This tiny tool helps you complete precise internal features faster, with fewer tool changes and consistently high-quality finishes. Its compact size, extended reach, and durable coatings support reliable performance across materials, making it a dependable choice for small-part manufacturing, fixtures, and precision components.
