The Carmex Carbide Tiny Tool is a compact boring bar designed for precision internal work in tight spaces. Crafted from solid carbide, this micro tool shines in boring applications and is versatile enough for light general turning. With a 3.1 mm minimum diameter, a 10 mm reach, and a nose radius of 0.05 mm, it delivers clean, accurate holes in small bores and hard-to-reach pockets.
- Compact micro-bore geometry: Access tight internal bores with a 3.1 mm minimum diameter, 10 mm reach, and a precise 0.05 mm nose radius for smooth, accurate hole finishes.
- BXC TiN-coated grade for stainless steels: Optimized for low cutting speeds, providing reliable cuts on stainless steels (ISO P30-P50 / K25-K40) with improved tool life and consistent performance.
- BMK sub-micron grade with triple PVD coating: Exceptional heat resistance and smooth cutting across a broad range of materials, delivering dependable performance for demanding jobs and general-purpose use.
This combination of tiny size, targeted coating options, and carbide rigidity helps you reduce tool changes, improve hole quality, and boost throughput in small-diameter machining tasks. Choose the BXC-coated option for stainless workpieces requiring stable cutting at lower speeds, or the BMK-grade for high-heat, general-purpose machining. Rely on precise geometry and durable coatings to consistently deliver clean finishes and reliable results, even on challenging materials.
