Carmex Carbide Tiny Tool - Boring Bar - MTR - BXC Grade - 1.2mm Minimum Diameter x 9mm Reach x R0

Carmex Carbide Tiny Tool is a micro boring bar crafted from solid carbide, designed for precision holes and small-diameter turning. Its compact form and rigid construction help you maintain tight tolerances in confined spaces. With a 1.2 mm minimum diameter, a 9 mm reach, and an R0 end geometry, this tiny tool enables clean entry and crisp cuts in confined bores.

Designed for both professional shops and hobbyist setups, the toolline covers boring and general turning tasks. The BXC Grade features a PVD TiN coating optimized for low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK variant offers a sub-micron grade with advanced PVD triple coating, delivering extremely high heat resistance and smooth cutting for broader material use.

• Ultra-small bore access: With a 1.2 mm minimum diameter and 9 mm reach, this tool reaches tight bores and intricate features, while the R0 geometry helps maintain clean entry and exit.
• TiN-coated BXC grade for stainless steels: The PVD TiN coating supports low cutting speeds and works well across a wide range of stainless steels, providing longer tool life and reliable cuts.
• BMK option for all-material versatility: The sub-micron BMK grade with advanced PVD triple coating delivers extremely high heat resistance and smooth cutting, extending performance across a broader range of materials.

This micro boring tool helps you achieve precise hole finishes with confidence, reduces downtime from wear, and delivers consistent surface quality on stainless steels and other materials. Its durable carbide construction provides dependable performance across demanding tasks, making it suitable for engineers, machinists, buyers, tradespeople, and hobbyists alike.
