The Carmex Carbide Tiny Tool - Boring Bar is a compact, solid carbide option designed for precise boring and reliable general turning. Built for tight bore work, it features a 5.1 mm minimum diameter, 40 mm reach, and a left-hand R0.2 nose radius to deliver accurate, clean cuts in challenging setups. This tool is well-suited to engineers, machinists, and hobbyists who demand consistent hole geometry and dependable performance.

• Carbide core with precise geometry: Delivers rigid, stable cutting for repeatable hole sizes and smooth finishes in boring and light turning tasks.
• BMK Grade with advanced PVD triple coating: Sub-micron BMK grade offers extremely high heat resistance and a smooth cutting action, enhancing performance across a wide range of materials (ISO K10–K20).
• BXC Grade with PVD TiN coating for stainless steels: TiN coating supports low cutting speeds and reduces wear on stainless steels (ISO P30–P50 / K25–K40), extending tool life and improving surface quality.

Designed for versatility and reliability, this carbide boring bar helps you complete tight-bore work and general turning with confidence. The combination of robust carbide construction and advanced coatings delivers durable edge life, consistent results, and the flexibility to handle a broad material range without frequent tool changes.
