Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precise bore work and versatile turning tasks. Its small footprint—4.1 mm minimum diameter with a 22 mm reach and a left-hand R0.1 nose—lets you access tight bores and maintain tight tolerances in a range of materials. Built for reliability, it’s suitable for engineers, machinists, and hobbyists who need consistent, repeatable results without sacrificing cutting stability.

This tool line offers two carbide grades to match different cutting conditions. The BXC grade features a PVD TiN coating optimized for low cutting speeds, delivering dependable performance with stainless steels (ISO P30-P50 / K25-K40). The BMK grade uses a sub-micron structure with an advanced PVD triple coating for high heat resistance and smooth cutting across a broad material set, making it a strong general-purpose option.

• PVD TiN-coated BXC grade for low-speed cutting: Optimized for slower feeds, this grade provides steady wear resistance and reliable results when machining stainless steels, helping you maintain consistent geometry at reduced cutting speeds.
• BMK sub-micron grade with triple PVD coating: Designed for high heat resistance and smooth cutting, offering extended life and dependable performance across a wide range of materials.
• Compact geometry for tight bores: With a 4.1 mm minimum diameter, 22 mm reach, and a left-hand R0.1 nose, it fits narrow bores and delivers precise, repeatable results in restricted spaces.

Designed to streamline workflows, the Carmex Tiny Tool helps you finish jobs faster with fewer tool changes and consistent hole quality. Choose the BXC option for stainless steel work at lower speeds or the BMK option when you need robust heat resistance and smoother cuts across various materials. Its compact size and precise geometry empower you to tackle challenging bore features with confidence, delivering reliable performance job after job.
