Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade - 2.1mm Minimum Diameter x 5mm Reach x R0.15 (Left Hand)

The Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for micro-internal work on small parts. With a 2.1 mm minimum diameter, 5 mm reach, and a small R0.15 nose radius in a left-hand configuration, it excels at accessing tight bores while maintaining rigidity. This makes it ideal for engineers, machinists, and hobbyists who need precise internal features without bulky tooling.

Built around BMK-grade carbide and finished with an advanced PVD coating, this tiny tool delivers exceptional heat resistance and a smooth cutting action. It’s engineered to perform reliably across a broad range of materials, including stainless steels, enabling consistent results in boring and general turning tasks.

• BMK-grade carbide with triple PVD coating: Sub-micron carbide construction with an advanced coating delivers excellent heat resistance and smooth cutting, extending tool life across a wide range of materials.
• Ultra-compact, left-hand boring bar (2.1 mm Ø, 5 mm reach): Access tight internal features with minimal overhang while maintaining rigidity and predictable results in small bore operations.
• General-purpose, durable performance: Optimized for boring and turning, delivering consistent results and reducing downtime in demanding shop environments.

Whether you're finishing tight internal bores or performing delicate internal turning, this Tiny Tool helps you complete parts faster with cleaner holes and fewer reworks. The BMK-grade carbide's heat resistance keeps cutting edges sharper longer, while the compact geometry enables stable, accurate setups in confined bores. Built for reliability, it delivers consistent results across materials, including stainless steels, making it a dependable choice for both daily shop use and precision prototypes.
