The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for tight-bore work and general turning. With a 4.1 mm minimum diameter, 22 mm reach, and a left-hand R0.2 edge, it delivers reliable access and consistent finishes on stainless steels and a wide range of materials.
- BMK Sub-Micron Grade with PVD Triple Coating: Sub-micron BMK grade delivers extremely high heat resistance and a smooth cutting action for maximum performance and tool life across ISO K10–K20 materials.
- BXC TiN-Coated Grade for Low-Cutting Speeds: Optimized for stainless steels and low-speed cutting, providing controlled chip formation, reduced built‑up edge, and longer tool life (ISO P30–P50 / K25–K40).
- Compact, Left-Hand Geometry (4.1 mm dia, 22 mm reach, R0.2): Designed for tight bores and short reach work, enabling repeatable finishes and easy setup in a variety of materials.
This tool line is built to simplify setup, reduce downtime, and improve finish quality. The BMK grade handles demanding materials with excellent heat tolerance, while the BXC grade provides reliable performance at lower cutting speeds for stainless steels. The compact geometry allows access to challenging features, minimizes tool changes, and supports consistent results across multiple passes—helping you complete projects faster with confidence.
