The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision small-diameter bores and versatile turning work. With a minimum diameter of 5.1 mm, a reach of 40 mm, and a left-hand orientation featuring a 0.2 mm nose radius, this tool is ideal for tight bores and delicate finishing tasks. It’s built to cover both dedicated boring jobs and general turning, making it a reliable choice for workshops that run mixed programs.

• Two coating options for adaptable performance: Choose BXC for low-speed cutting with PVD TiN coating, especially effective on stainless steels, and BMK for high-heat resistance with a sub-micron grade and advanced PVD triple coating—together delivering smoother cuts and reliable results across a variety of materials.
• Compact geometry for tight bore work: The 5.1 mm minimum diameter, 40 mm reach, left-hand setup, and a precise 0.2 mm nose radius enable clean entry, steady engagement, and controlled chip formation in small-diameter bores.
• Broad material compatibility: Designed as a general-purpose tool line for all materials, with BXC optimized for stainless steels at low speeds and BMK delivering robust performance and smooth cutting across a wide range of alloys.

This tiny carbide boring bar helps you achieve consistent bore sizes and clean surface finishes, while reducing tool changes and downtime. The dual coating options provide flexibility to match material and cutting conditions, so you can rely on stable performance from roughing through finishing passes and maintain productive workflows across various turning and boring applications.
