The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision boring and reliable turning. With a 5.1 mm minimum diameter, 30 mm reach, and left‑hand geometry, it excels in tight pockets, grooving, and finishing passes on standard lathes.

This tool is part of Carmex’s line of solid carbide bars and is suitable for a range of materials and applications. It offers two performance-coated options: BXC TiN coated grade for low cutting speeds and excellent performance with a wide range of stainless steels (ISO P30-P50 / K25-K40); and BMK sub‑micron grade with an advanced PVD triple coating, delivering extremely high heat resistance and smooth cutting for general‑purpose use across materials (ISO K10-K20).

• Compact boring bar for tight bores: 5.1 mm minimum diameter with 30 mm reach and a precise R0.2 corner radius enable clean, accurate holes in confined spaces and finishing passes.
• Dual coating options for versatile performance: BXC TiN coating reduces friction for low-speed stainless‑steel work, while the BMK triple PVD coating provides heat resistance and smooth cutting across a broad material range.
• Left-hand geometry for reliable engagement: Designed for left‑hand cutting setups, delivering predictable chip flow and consistent edge performance in everyday turning and boring tasks.

Used in a wide range of turning and boring operations, this tool helps you achieve consistent hole quality, reduces tool changes, and supports longer life in demanding materials. Its robust carbide composition and tailored coatings translate to dependable performance, helping you finish jobs faster with fewer interruptions and better surface finishes.
