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

The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for small-diameter bore work and general turning. With a 1.2 mm minimum diameter, 9 mm reach, and an R0 nose, this compact tool delivers precise starts and stable performance on tight features.

It is available in two high-performance grades to cover a wide range of jobs: BMK and BXC. BMK is a sub-micron grade with advanced PVD triple coating for extremely high heat resistance and a smooth cutting action across materials. BXC features a PVD TiN coating optimized for low cutting speeds and reliable performance with a wide range of stainless steels (ISO P30-P50 / K25-K40). These coatings help extend tool life and maintain a consistent finish in demanding applications.

• BMK Sub-micron Grade with PVD Triple Coating: Delivers exceptional heat resistance and a smooth cutting action for maximum performance and long tool life across materials.
• BXC PVD TiN Coating for Low-Speed Stainless Cutting: Optimized for low cutting speeds on stainless steels, reducing wear and improving reliability in everyday boring and turning tasks.
• Compact 1.2 mm Diameter, 9 mm Reach with R0 Nose: Lets you access tight bores and small features with precision while maintaining stiffness and clean, accurate starts and finishes.

Whether you’re a precision engineer, a shop technician, or a hobbyist tackling micro-geometry parts, this carbide tiny tool helps you achieve consistent bore starts, smooth cutting action, and reliable tool life. The dual-grade options let you match material and speed to your workflow, improving throughput and finishing quality on small-diameter projects.
