Carmex Carbide Tiny Tool - Boring Bar - MTL - BXC Grade - 5.1mm Minimum Diameter x 40mm Reach x R0.2 (Left Hand)

The Carmex Carbide Tiny Tool is a compact solid carbide boring bar designed for precise small‑diameter boring and general turning tasks. With a 5.1 mm minimum diameter, a 40 mm reach, a left‑hand orientation, and a tight R0.2 corner radius, it excels in tight bores and delivers clean, accurate holes.

Designed for durability, the BXC‑grade coating uses PVD TiN for low cutting speeds, making it well‑suited for a broad range of stainless steels (ISO P30–P50 / K25–K40). The carbide substrate and TiN coating provide smooth cutting action and reliable tool life across common machining jobs.

• Compact micro-boring design: 5.1 mm minimum diameter, 40 mm reach, and left-hand orientation allow access to tight bores and stable cutting in confined spaces.
• TiN-coated BXC grade for stainless steels: PVD TiN coating optimized for low cutting speeds delivers longer tool life and smoother, more reliable cuts on a wide range of stainless steels (ISO P30–P50 / K25–K40).
• Left‑hand geometry with a sharp R0.2 corner radius: Provides stable entry and a high‑quality surface finish by reducing chatter and improving precision in small-diameter boring and turning.

This tool offers a dependable solution for high‑precision small bores and versatile general turning. The carbide core, combined with TiN coating, resists wear, helps maintain tight tolerances, and supports efficient production. Its compact form, left-hand orientation, and fine corner radius streamline setups, shorten cycle times, and deliver consistent hole sizes and smooth finishes across a range of materials.
