The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for small-diameter bore work and general turning. With a minimum diameter of 5.1 mm, a reach of 22 mm, and a precise R0.1 edge, it helps you achieve tight tolerances in confined spaces.

Part of the MTR - TNX Grade family, this tool supports two coating options to match cutting conditions: BXC is a PVD TiN-coated grade optimized for low cutting speeds and works well with a wide range of stainless steels (ISO P30-P50 / K25-K40); BMK is a sub-micron grade with an advanced PVD triple coating, delivering extremely high heat resistance and smooth cutting, suitable as a general purpose option for all materials.

• Ultra-compact boring bar for tight bores: 5.1 mm minimum diameter, 22 mm reach, and an R0.1 corner radius enable accurate, clean holes in confined spaces with minimal tool deflection.
• Coatings chosen for durability and performance: BXC TiN-coated grade supports low-speed cuts and stainless steels (ISO P30-P50 / K25-K40); BMK sub-micron grade with triple PVD coating provides high heat resistance and smooth cutting across a broad range of materials.
• Solid carbide construction for reliability: Rugged, wear-resistant material delivers long tool life and stable cutting across demanding jobs.

By choosing the Carmex Tiny Tool for boring and general turning tasks, you can streamline setups, maintain tight tolerances, and achieve consistent finishes with less downtime. The dual coating options let you optimize performance for stainless steels and other materials, while the compact form fits into tight fixtures and small machine envelopes. Built for durability and dependable results, this tiny tool helps you get repeatable, high-quality results across your projects.
