Carmex Carbide Tiny Tool - Boring Bar - MTL - BMK Grade - 6.1mm Minimum Diameter x 35mm Reach x R0.2 (Left Hand)

The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precise small‑diameter holes and general turning. Its 6.1 mm minimum diameter, 35 mm reach, and left‑hand nose with an R0.2 radius provide stable, accurate engagement in tight bores, making it a reliable choice for both prototype work and production runs.

This tool comes in two advanced coating grades to maximize performance across materials. The BXC grade uses a PVD TiN coating optimized for low cutting speeds and is particularly effective with a wide range of stainless steels (ISO P30‑P50 / K25‑K40). The BMK grade features a sub‑micron structure with an advanced PVD triple coating, delivering extremely high heat resistance for maximum performance and smooth cutting across a broad material spectrum (ISO K10‑K20). This versatility lets you tailor the tool to your specific application without swapping tooling.

• Compact, left‑hand boring bar with precise nose radius: 6.1 mm minimum diameter, 35 mm reach, and a 0.2 mm nose radius (R0.2) tuned for tight tolerances and clean bore finishes.
• Two advanced PVD coating grades for versatility: BXC TiN coating supports low‑speed cutting on stainless steels, while BMK’s sub‑micron, triple‑coated design handles higher heat and a wide range of materials for smoother cuts.
• Durable carbide core with wear‑protective coatings: High‑wear‑resistance construction reduces tool changeovers, promotes consistent hole quality, and extends tool life in demanding turning and boring tasks.

Designed to improve workflow and outcomes, the Carmex Tiny Tool helps you achieve accurate bores with fewer passes, less rework, and dependable performance across materials. Its compact geometry fits tight setups, while the dual coating options let you optimize for speed, heat, and material type—delivering reliable results from prototype to production.
