Carmex Carbide Tiny Tool - Boring Bar - MTL - K20 Grade - 1mm Minimum Diameter x 6mm Reach x R0.05 (Left Hand)

The Carmex Carbide Tiny Tool is a compact boring bar crafted from solid carbide for precise small-bore work and general turning. Designed for tight spaces, it delivers clean, accurate holes with dependable performance. This model offers a 1 mm minimum diameter, a 6 mm reach, and a left-hand R0.05 edge, making it ideal for deep, narrow bores and controlled entry and exit in demanding setups. Two coated carbide options expand its versatility: BXC TiN-coated grade optimized for low-speed cutting in stainless steels, and BMK sub-micron grade with advanced PVD triple coating for extreme heat resistance and smooth cutting across a broad material range. These coatings are designed to maximize tool life and consistent results in real-world shop conditions.

• Ultra-precise mini bore capability: Designed for holes as small as 1 mm with a 6 mm reach and a refined R0.05 corner, enabling accurate, repeatable boring in tight workpieces and deep pockets.
• Coated carbide options for versatility: Choose BXC TiN for reliable performance at low speeds on stainless steels, or BMK with a triple PVD coating for exceptional heat resistance and smooth cutting across many materials.
• Left-hand geometry for reliable boring: Left-hand orientation promotes stable engagement, easier chip evacuation, and consistent finishes in typical boring setups.

This tiny boring bar is built to reduce setup time, cut fewer passes, and extend tool life in daily machining routines. By pairing a compact size with durable coatings and a refined edge geometry, it helps you achieve precise bore results, minimize downtime, and keep your workflows productive—even in tight tolerances and challenging materials.
