The Carmex Carbide Tiny Tool is a compact boring bar crafted for precision in tight bores and small turning jobs. Built from solid carbide and offered in TNX grade, it delivers rigid, dependable performance where space is limited—perfect for engineers, machinists, and hobbyists who value clean, repeatable finishes.

Designed for boring and light turning tasks, this tiny bar features a 5.1 mm minimum diameter, a 15 mm reach, and a nose radius of R0.2, enabling accurate depth control and smooth entry into confined features.

• Slim, rigid geometry for tight bores: The compact 5.1 mm diameter and 15 mm reach maintain cutting stability in restricted spaces, delivering precise, chatter‑free results across boring and turning operations.
• Dual coating options for versatility: Choose BXC TiN coating for stainless steels at lower speeds, or BMK sub‑micron grade with triple PVD coating for high heat resistance and smooth cutting across a wide range of materials.
• Durable carbide construction for long tool life: Solid carbide core and advanced coatings resist wear, helping you maintain accuracy and reduce tool changes over repeated cycles.

This tiny boring bar is designed to fit demanding workflows without compromising performance. Its compact size, reliable coatings, and high-strength carbide construction translate into faster setups, consistent finishes, and fewer rework cycles, making it a smart choice for both production environments and precision-focused projects.
