The Carmex Carbide Tiny Tool, a TNX Grade boring bar, is a compact solution for tight internal features in small‑diameter workpieces. It also handles general turning tasks when required, giving you a versatile option for precision machining. With a 4.1 mm minimum bore, 30 mm reach, and a left‑hand R0.2 nose, it delivers reliable, repeatable finishes in confined spaces.

• Ultra-compact bore capability: 4.1 mm minimum diameter, 30 mm reach, and a precise R0.2 nose enable clean, accurate internal features in small parts where space is limited.
• Coated carbide options for wear resistance and heat handling: Choose BXC TiN coating for reliable performance at low cutting speeds on stainless steels, or BMK sub-micron grade with a triple PVD coating for exceptional heat resistance and smooth cutting across a wide range of materials.
• Left-hand geometry for flexible setup: The left-hand orientation supports specific machine configurations, helping deliver stable cuts and consistent bore finishes in demanding applications.

The Carmex Tiny Tool delivers a durable, precise boring bar designed to withstand the rigors of small‑diameter work. Its solid carbide construction provides long tool life and predictable performance, reducing downtime and rework. Whether you’re optimizing production runs or tackling intricate inner features, this tool offers reliable results across stainless steels and general turning tasks, backed by the proven geometry and coating options that help you finish with confidence.
