The Carmex Carbide Tiny Tool is a precision solid carbide boring bar designed for tight spaces and fine finishing on small-diameter parts. With a 7.1 mm minimum diameter, 22 mm reach, and a 0.2 mm nose radius, it delivers accurate bores and controlled turning in hard-to-reach areas.

This tool suits both professional shops and discerning hobbyists who demand reliable, consistent results across a range of materials. It offers two high-performance coating grades to cover diverse machining needs, from stainless steels to general-purpose applications.

• Compact geometry for tight bores: 7.1 mm minimum diameter, 22 mm reach, and R0.2 nose radius enable precise, repeatable boring and finishing in confined spaces, reducing setup time and manual adjustments.
• BXC TiN-coated grade for stainless steels: PVD TiN coating designed for low cutting speeds, delivering cleaner cuts and longer tool life when working with 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 dependable performance across a broad material range and demanding conditions.

With its robust carbide construction and thoughtful coating options, the Carmex Tiny Tool supports reliable, repeatable results, minimizes downtime, and helps you achieve clean, accurate bores and finishing in small workpieces—packing precision and durability into a compact, easy-to-use tool.
