The Carmex Carbide Tiny Tool Boring Bar is a compact, solid carbide option built for precision in small bores and general turning alike. With a 6.1 mm minimum diameter, a 30 mm reach, and an R0.2 corner radius in a left-hand orientation, it delivers stable cutting and repeatable results in tight spaces. Ideal for engineers, machinists, and hobbyists who need dependable performance in stainless steels and other materials.

• Left-hand, compact boring bar with precise geometry: Designed for tight bores and delicate depth control, featuring a 6.1 mm minimum diameter, 30 mm reach, and an R0.2 corner radius for smooth, accurate cuts.
• PVD TiN-coated BXC grade for wear resistance: The TiN coating reduces wear and buildup at low cutting speeds, helping your tool last longer when machining stainless steels (ISO P30-P50 / K25-K40).
• Versatile for boring and turning: While optimized for boring, this solid carbide bar handles general turning tasks too, minimizing tool changes and expanding your machining options.

This tiny tool pairs a robust carbide core with a protective coating to deliver long-lasting performance, predictable finishes, and confident results across a range of materials. Its focused geometry and coating work together to maintain stability, reduce downtime, and help you hit tight tolerances on small-diameter features with fewer reworks.
