Carmex Carbide Tiny Tool - Boring Bar - MTL - TNX Grade - 5.1mm Minimum Diameter x 30mm Reach x R0.2 (Left Hand)

The Carmex Carbide Tiny Tool is a compact, solid carbide boring bar designed for precision boring and versatile turning in tight spaces. Aimed at engineers, machinists, and hobbyists alike, it delivers accurate hole geometry with dependable performance in a range of materials.

This left‑hand tool features a 5.1 mm minimum diameter, 30 mm reach, and a 0.2 mm nose radius, making it ideal for small-diameter bores and close-clearance operations. It belongs to Carmex’s TNX‑grade carbide family and can be paired with the line’s coating options—BXC TiN for low-speed cutting in stainless steels, and BMK with a sub‑micron, triple PVD coating for high heat resistance—so you can tailor performance to your material and cutting conditions.

• Compact, left‑hand design for tight bores: 5.1 mm minimum diameter, 30 mm reach, and a precise R0.2 nose radius combined with LH orientation for predictable tool paths and consistent hole quality in constrained cavities.
• Two coating options for versatile material performance: BXC TiN coating optimizes wear and efficiency at lower speeds on stainless steels (ISO P30–P50 / K25–K40); BMK triple PVD coating delivers high heat resistance and smooth cutting across a wide range of materials.
• Durable carbide construction for long life: TNX‑grade carbide provides sharp edge retention and rigidity, helping extend tool life and reduce downtime during demanding boring and turning jobs.

Designed to enhance accuracy, reduce setup and cycle times, and deliver reliable results across multiple materials, the Carmex Tiny Tool helps you complete tight-bore projects with confidence. Its compact geometry and dependable coatings translate to smoother cuts, fewer tool changes, and improved overall workflow on both professional and DIY machining setups.
