The Carmex Carbide Tiny Tool is a solid carbide boring bar designed for precision in tight spaces and versatile turning tasks. With an 8.1 mm minimum diameter, a 35 mm reach, and a precise R0.2 nose radius, it’s ideal for small-diameter bores and close-tolerance work. This tool is suitable for engineers, machinists, and hobbyists who need reliable boring performance in a compact form factor.

It leverages two advanced coating grades to match different materials and speeds. The BXC - PVD TiN coated grade is optimized for low cutting speeds and performs well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK - Sub-micron grade features an advanced PVD triple coating for exceptional heat resistance and smooth cutting, offering general-purpose capability across materials.

• Compact, precise geometry for tight bores: 8.1 mm minimum diameter, 35 mm reach, and a precise R0.2 nose radius enable accurate holes in confined spaces with clean finishes.
• Coating options for performance and reliability: Choose BXC TiN for efficient low-speed cutting on stainless steels or BMK’s triple-coated, high-heat-resistant surface for demanding materials and longer tool life.
• Solid carbide durability for versatile boring and turning: Built for boring and general turning, the TNX-grade carbide delivers consistent results and dependable tool life across a range of materials.

This tiny boring bar helps streamline workflows by delivering consistent hole quality, reducing tool changes, and maintaining smooth cutting across materials. Its sturdy carbide core and purpose-built coatings translate to fewer interruptions, improved finish quality, and more productive machining sessions.
