The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision boring and light turning in tight spaces. With a 1.2 mm minimum diameter, 9 mm reach, and left-hand R0 geometry, this tiny tool delivers accurate engagement and clean finishes in small-diameter holes and detailed workpieces.

• BXC TiN-coated grade for low-speed stainless cutting: Optimized for slower cutting speeds and a wide range of stainless steels, this coating reduces friction and helps extend tool life while delivering reliable, consistent finishes (ISO P30-P50 / K25-K40).
• BMK sub-micron grade with triple PVD coating for high heat resistance: Built for demanding applications, this advanced coating delivers extremely high heat resistance and smooth cutting performance, making it suitable for general-purpose use across materials.
• Compact carbide design with precise left-hand geometry: The 1.2 mm minimum diameter, 9 mm reach, and R0 nose provide rigid, precise engagement in tight bores and restricted work areas, helping you maintain tight tolerances and quality finishes.

Designed for engineers, machinists, and hobbyists alike, this tiny boring bar helps you achieve consistent results, reduce downtime from tool changes, and maintain productive workflows across stainless steels and other materials. Its sturdy carbide build, dual-grade coating options, and compact geometry empower reliable performance in challenging, space-limited machining tasks.
