Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide option built for precision internal boring and dependable general turning. With a 7.1 mm minimum diameter, a 30 mm reach, and a 0.2 mm nose radius, this tiny tool delivers tight bore control in confined spaces while maintaining rigidity and consistent cut quality. It’s designed for engineers, machinists, and hobbyists who need reliable performance in small-diameter workpieces.

• 7.1 mm minimum diameter with 30 mm reach and R0.2 nose: Enables precise boreNorthing in tight cavities and deep recesses, reducing tool deflection and improving positional accuracy.
• BXC Grade with PVD TiN coating for low-speed cutting: TiN coating minimizes friction and heat at lower cutting speeds, extending tool life and delivering smoother finishes on stainless steels (ISO P30-P50 / K25-K40).
• BMK Grade with sub-micron core and triple PVD coatings: Exceptional heat resistance and smooth cutting across a wide material range, providing reliable, consistent performance for demanding applications.

Designed as a versatile solid carbide bar, the Carmex Tiny Tool excels in boring while remaining capable for general turning tasks. The dual-grade coating approach combines strength, heat tolerance, and smooth engagement, helping you achieve clean surfaces, longer tool life, and fewer tool changes in mixed-material workflows.
