The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision turning in tight spaces. Its 1.2 mm minimum diameter, 9 mm reach, and left-hand R0 geometry let you bore small-diameter holes with clean, repeatable results. This makes it ideal for engineers, machinists, and hobbyists working in tight tolerances or limited-access features.

Part of Carmex's line of carbide bars, it supports boring applications and general turning. Choose from two coated grades: BXC, a PVD TiN-coated option optimized for low cutting speeds and stainless steels (ISO P30–P50 / K25–K40); and BMK, a sub-micron grade with advanced PVD triple coating for extremely high heat resistance and smooth cutting across a broad range of materials.

• Tiny-diameter, long-reach design: 1.2 mm minimum diameter and 9 mm reach let you access tight bores and pockets for precise, consistent cuts.
• PVD TiN-coated BXC grade for stainless steels at low speeds: Reduces friction and heat buildup, extending tool life and delivering stable, clean cutting on stainless steels (ISO P30–P50 / K25–K40).
• BMK sub-micron grade with triple coating for high heat resistance: Advanced PVD coating provides extremely high heat tolerance and smooth cutting across a wide material range, making it suitable for general turning as well as demanding applications.

This tiny tool helps you tackle small-diameter bores and precision turning in a single setup, reducing tool changes and cycle times. The hard carbide core paired with protective coatings maintains sharpness through long runs, delivering consistent finishes and dependable performance across stainless steels and other common materials. By selecting the BXC or BMK grade to suit your material and speed, you can optimize reliability, minimize downtime, and improve overall productivity in your machining workflow.
