The Carmex Carbide Tiny Tool is a compact boring bar built for precision in small bores and general turning. With a left‑hand cutting geometry, a 5.1 mm minimum diameter, 22 mm reach, and a 0.2 mm nose radius, it fits tight spaces while delivering reliable performance. The tool family offers two coating grades—BXC TiN for steady performance at lower speeds on stainless steels and BMK with a sub‑micron grade and triple PVD coating for excellent heat resistance across a broad range of materials—so you can choose the right balance of speed, life, and finish for your job.

• Dual-grade coatings for versatile materials: BXC TiN provides dependable cutting at low speeds on stainless steels, while BMK’s sub‑micron, triple-coated formulation delivers excellent heat resistance and smooth cutting across various alloys.
• Small-diameter, long-reach geometry for tight bores: With a 5.1 mm minimum diameter, 22 mm reach, and a precise R0.2 nose radius in a left‑hand configuration, it excels in confined pockets and delicate boring passes without compromising accuracy.
• Solid carbide durability for reliable cuts: The rigid carbide core minimizes tool deflection and chatter, supporting steady chip formation and longer tool life for demanding boring and turning tasks.

This tiny boring bar helps you complete precision work with fewer passes, delivering consistent results and improved workflow in tight cavities and challenging materials. By selecting the appropriate coating grade for your material and cutting conditions, you gain reliable performance, reduced downtime, and a smoother path from setup to finished part.
