Carmex Carbide Tiny Tool - Boring Bar - MTL - BXC Grade - 4.1mm Minimum Diameter x 10mm Reach x R0.2 (Left Hand)

The Carmex Carbide Tiny Tool Boring Bar is a compact, solid carbide solution designed for precision boring and light turning in tight spaces. With a 4.1 mm minimum diameter, a 10 mm reach, and a left-hand R0.2 tip, it provides reliable access to narrow bores and finishing passes on small parts.

Coated in PVD TiN for the BXC Grade, this bar minimizes wear at lower cutting speeds and pairs well with a wide range of stainless steels (ISO P30-P50 / K25-K40). Built for dependable performance in everyday machining tasks, it’s a smart choice for operators who demand consistent results.

• Ultra-compact bore access: 4.1 mm minimum diameter and 10 mm reach enable entry into tight cavities and precise finishing passes without tool changes.
• TiN-coated BXC Grade for wear resistance: PVD TiN coating reduces friction and wear at low cutting speeds, extending tool life when machining stainless steels.
• Left-hand geometry with R0.2 corner: Left-hand orientation and a 0.2 mm corner radius promote smooth entry and clean, burr-free finishes in restricted bores.

This tiny boring bar helps you tackle micro-boring and finishing tasks with confidence, improving workflow and finish quality across small-diameter workpieces and stainless steel applications.
