Carmex Carbide Tiny Tool - Boring Bar - MTL - TNX Grade - 2.5mm Minimum Diameter x 10mm Reach x R0 (Left Hand)

Carmex Carbide Tiny Tool - Boring Bar is a compact solid carbide bar designed for micro-boring and general turning in tight spaces. With a 2.5 mm minimum diameter, a 10 mm reach, and a left-hand R0 tip, it delivers precise, repeatable holes in small workpieces while fitting into confined setups. This tool is ideal for engineers, machinists, and hobbyists who need reliable performance in limited-access bores.

• Ultra-compact micro-boring geometry: 2.5 mm minimum diameter and 10 mm reach in a left-hand R0 configuration, enabling precise internal bores in tight spaces with consistent wall quality.
• Coating options for versatile cutting: BXC with PVD TiN offers efficient, low-speed cutting for stainless steels (ISO P30–P50 / K25–K40); BMK features a sub-micron grade with triple PVD coating for high heat resistance and smoother cutting across more materials.
• Durable carbide with proven reliability: Solid carbide core paired with advanced coatings reduces wear and heat buildup, providing consistent tool life and finishing quality in demanding boring and turning tasks.

In use, this tiny boring bar helps you achieve clean, accurate holes in small-diameter workpieces while maintaining stable cuts and predictable performance across a range of materials. The dual TNX-grade coatings give you flexibility to optimize for stainless steel or general-purpose material cutting, and the compact, left-hand geometry supports reliable setup and repeatable results even in confined tooling environments.
