The Carmex Carbide Tiny Tool Boring Bar is a compact, solid carbide cutting tool designed for precision boring in tight spaces. It features a 2.1 mm minimum diameter, 15 mm reach, and a left-hand R0.1 nose to deliver stable, accurate cuts in small bores and finish-ready surfaces. While primarily built for boring, it also handles general turning, making it a versatile choice for everyday machining tasks.

The tool is offered in advanced coating grades to match your material and speed conditions. The BXC TiN-coated grade excels at low cutting speeds and performs well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK grade uses a sub-micron structure with a triple PVD coating for exceptional heat resistance and smooth cutting across materials, delivering reliable, general-purpose performance.

• Compact size for precise small-diameter bores: The 2.1 mm minimum diameter, 15 mm reach, and R0.1 left-hand nose provide tight, accurate holes with minimal tool deflection and a smooth finish.
• Coatings tailored for reliability: Choose BXC TiN for low-speed stainless work or BMK’s triple-coated, high-heat-resistant design for durable, consistent cuts across a broad material range.
• Versatile for boring and turning: Designed primarily for boring, it also handles general turning, reducing tool changes and expanding machining options in a single tool.

This carbide tiny tool helps streamline setups, maintain tight tolerances, and achieve consistent finishes across demanding materials. Its specialized coatings and compact geometry support longer tool life and dependable performance in busy production or workshop environments.
