Introducing the Carmex Carbide Tiny Tool – Boring Bar, a compact, solid carbide bar designed for precise internal bores and versatile turning. Built for engineers, machinists, and hobbyists alike, it excels in tight spaces where accuracy and reliability matter most. This tiny bar is optimized for boring applications and delivers consistent hole sizes with dependable performance on a wide range of materials.

With a 2.1 mm minimum diameter, 5 mm reach, and an R0.15 left-hand nose radius, this tool plays well in small-diameter bores and narrow cavities. The BXC TiN-coated grade provides durable performance at lower cutting speeds, delivering smoother cuts and extended tool life when working with stainless steels.

• BXC TiN coating for durable, low-speed cutting: PVD TiN coating enhances wear resistance and surface finish on stainless steels (ISO P30-P50 / K25-K40), helping tools last longer and maintain precision in boring and turning.
• Ultra-compact geometry: 2.1 mm min diameter, 5 mm reach, R0.15 nose: A tiny, precise profile that reaches deep into small bores while delivering clean, consistent finishes thanks to the fine nose radius.
• Left-hand cutting orientation for efficient boring: Designed for left-hand operations, providing stable chip flow and reliable performance in constrained cavities and routine cycles.

This tiny carbide boring bar helps you finish small-diameter bores with confidence, improving workflow and reducing downtime. Its durable coating, precise geometry, and specialized left-hand orientation combine to deliver smooth cutting, repeatable hole sizes, and enhanced overall part quality.
