Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for internal holes in small parts. With a 1 mm minimum diameter, 4 mm reach, and a precise nose radius of R0.05, it delivers accurate, repeatable results in tight bores while remaining versatile enough for general turning tasks. This tiny tool is ideal for engineers, machinists, hobbyists, and job shops working on miniature components where precision and reliability matter.

Two advanced coating grades are available to match material and cutting conditions:

• BXC TiN coated grade: optimized for low cutting speeds and stainless steels, aligned with ISO P30-P50 / K25-K40 ranges, delivering stable performance on standard stainless applications.
• BMK sub-micron grade with triple PVD coating: engineered for extremely high heat resistance and smooth cutting across a broad material spectrum (ISO K10-K20), making it a reliable all-material option.

This tiny boring bar combines a rigid carbide core with specialized coatings to provide long edge life, consistent finishes, and dependable performance even in demanding small-diameter machining. The result is fewer tool changes, steadier cuts, and improved surface quality on miniature bores and tight-pocket turning tasks.
