The Carmex Carbide Tiny Tool (MTR, BXC Grade) is a precision solid carbide boring bar designed for small-diameter boring and fine turning on lathes and compact milling centers.

With a 1.5 mm minimum diameter, 6 mm reach, and a true R0 tip, it enables precise starts in tight features and ensures clean bore finishes across a range of materials.

• Ultra-small diameter with zero-radius tip: Enables precise starts and tight tolerances in small bores, with a 1.5 mm minimum diameter and an R0 tip for flawless entry and surface finish.
• Long reach for deep bores: The 6 mm reach lets you access deep pockets and through-holes without repositioning, improving consistency and reducing setup time.
• Coating options tuned for reliability: Choose BXC TiN-coated grade for low cutting speeds and stainless steels, or BMK sub-micron grade with triple PVD coating for high heat resistance and smooth cutting—designed for general use across materials.

With these features, the Carmex Tiny Tool helps you improve workflow, reduce downtime, and achieve reliable, repeatable bore finishes across a range of materials. The combination of small diameter, controlled reach, and advanced coatings supports tight tolerances, efficient setups, and longer tool life in everyday shop work.
