The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precise work in tight spaces and general turning. It features a 4.1 mm minimum diameter, 15 mm reach, and a left-hand R0.1 nose for accurate, repeatable bores on small parts. This tool line includes two coating grades—BXC TiN and BMK triple-coated—to optimize performance across a range of materials and speeds, including stainless steels.

• Compact, precise bore geometry: 4.1 mm minimum diameter, 15 mm reach, and a left-hand R0.1 nose deliver accurate, repeatable holes in confined areas, with stable cuts for small-diameter bores.
• Coating options for versatility: BXC TiN coating is tuned for low cutting speeds and works well with stainless steels (ISO P30-P50 / K25-K40); BMK offers a sub-micron grade with triple PVD coating for high heat resistance and smooth cutting across a broad material range.
• Durable carbide construction for reliable cutting: Solid carbide body provides stiffness and long tool life, while coatings reduce wear and heat buildup to maintain consistent performance in demanding boring and turning tasks.

This tiny tool helps you complete tight-bore projects with confidence, delivering consistent results in stainless steel and other materials. Its robust carbide core and advanced coatings reduce chatter and wear, enabling smoother cuts, longer intervals between tool changes, and reliable performance across a variety of boring and turning operations.
