Carmex Carbide Tiny Tool - Boring Bar - MTR - BMK Grade - 2.1mm Minimum Diameter x 15mm Reach x R0.1

Part of Carmex's solid carbide bar lineup, the Carmex Carbide Tiny Tool is a compact boring bar designed for micro‑machining and small‑diameter work. With a 2.1 mm minimum diameter, 15 mm reach, and an R0.1 tip, it provides access to tight bores and internal features while maintaining precise cutting. While designed primarily for boring, the bars also handle general turning tasks, making it a versatile choice for engineers, machinists, and hobbyists working in constrained spaces. Available in BMK and BXC coatings to match material and speed requirements: BMK offers a sub‑micron grade with triple PVD coating for high heat resistance and smooth cutting; BXC uses a PVD TiN coating optimized for low cutting speeds and stainless steels.

• Tight-diameter access and reach: 2.1 mm minimum diameter, 15 mm reach, and an R0.1 tip enable precise cutting in tight bores and internal profiles, reducing the need for multiple tools in micro‑machining setups.
• BMK grade—high heat resistance and smooth cutting: Sub‑micron grade with advanced PVD triple coating delivers extremely high heat resistance and smooth cutting operation for reliable performance across materials.
• BXC TiN coated option for stainless steels at low speeds: PVD TiN coating optimized for low cutting speeds, works well with a wide range of stainless steels (ISO P30-P50 / K25-K40), helping control wear and extend tool life at slower feeds.

Whether you’re fabricating tiny bores, finishing internal profiles, or performing general turning in tight spaces, this tiny carbide tool delivers dependable, repeatable results. The combination of BMK’s durability and the BXC’s wear resistance for stainless steel work provides options to extend tool life, reduce downtime, and maintain smooth finishes across demanding micro‑machining tasks.
