Meet the Carmex Carbide Tiny Tool – a compact, solid carbide boring bar designed for tiny bores and tight spaces. With a 4.1 mm minimum diameter, 30 mm reach, and R0.2 left-hand geometry, it delivers precise, repeatable results in boring operations and is also suitable for general turning. Available in two coatings to match your material and cutting conditions: BXC TiN for stainless steels at lower speeds, and BMK with a sub-micron, triple coating for high-heat performance and broad material compatibility.

• Compact, precise boring geometry: 4.1 mm minimum diameter, 30 mm reach, and R0.2 left-hand geometry enable accurate bores in tight spaces and easy setup on small lathes.
• BXC TiN coating for stainless steels: PVD TiN coating designed for low cutting speeds, delivering wear resistance and extended tool life when machining stainless steels (ISO P30-P50 / K25-K40).
• BMK sub-micron grade with triple coating: Advanced PVD triple coating provides extremely high heat resistance and smooth cutting, offering reliable performance across a broad range of materials (ISO K10-K20; general purpose for all materials).

This combination delivers reliable, repeatable performance across materials and applications, helping you maintain tight tolerances, achieve smooth finishes, and keep your workflow moving with longer tool life and fewer tool changes.
