Carmex Carbide Tiny Tool - Boring Bar - MTL - BXC Grade - 2.1mm Minimum Diameter x 15mm Reach x R0.1 (Left Hand)

Carmex Carbide Tiny Tool is a precision boring bar made from solid carbide, designed for micro and small-diameter internal turning and boring. With a 2.1 mm minimum diameter, a 15 mm reach, and a left-hand configuration, it enables tight access and controlled cuts in small bores, making it ideal for engineers, machinists, hobbyists, and technicians working on compact components.

• Ultra-small diameter for tight bores: Access narrow internal spaces with a 2.1 mm minimum diameter, enabling precise geometry in miniature parts and tight tolerances, while reducing overhang for improved rigidity and control.
• Two coating grades for versatility: Choose the BXC TiN-coated grade for wear resistance at low cutting speeds on stainless steels, or the BMK sub-micron grade with triple PVD coating for high heat resistance and smooth cutting across a broad range of materials.
• Left-hand geometry with a 0.1 mm nose radius (R0.1): Left-handed orientation paired with a fine nose radius delivers clean finishes and tight bore tolerances, with reduced chatter and smoother tool engagement.

This tiny boring tool helps you streamline setups and reduce downtime by enabling precise entrances and consistent finishes in small-diameter work. The carbide core and specialized coatings deliver reliable tool life and predictable performance across stainless steels and other materials, making it a dependable choice for both dedicated boring work and occasional general turning. Whether you're prototyping delicate parts or running production batches, this tool supports faster cycles, better surface quality, and fewer tool changes.
