Carmex Carbide Tiny Tool is a compact, solid‑carbide boring bar designed for precision internal features in tight spaces. It features a 4.1 mm minimum diameter, a 22 mm reach, and left‑hand cutting geometry with a nose radius of R0.05, making it ideal for small‑bore work and light turning tasks. Built for reliability, this tool delivers consistent hole sizes and clean finishes even in challenging setups.

As part of Carmex’s carbide bar family, the BXC grade brings a TiN coating optimized for low cutting speeds and wide stainless steel compatibility, while the line also includes BMK sub‑micron grades with advanced PVD triple coatings for maximum heat resistance and smooth cutting across a broad material range.

• Coated for low-speed cutting performance: The TiN coating reduces friction and edge wear at lower cutting speeds, helping maintain tool life and delivering a consistent surface finish when machining stainless steels.
• High-heat resistance for demanding materials: BMK sub‑micron grade with triple PVD coating offers exceptional heat resistance and smooth cutting, maintaining stability and quality on tougher workpieces.
• Compact, precise geometry for tight bores: 4.1 mm minimum diameter with 22 mm reach and R0.05 nose radius in a left‑hand configuration lets you reach small internal features with fewer passes and tighter tolerances.

With the Carmex Tiny Tool, you gain reliable, repeatable boring results in tight spaces, reduced downtime from longer tool life, and versatile performance across common machining tasks. The TiN‑coated BXC option protects the edge on stainless steels, while the BMK variant handles higher heat and tougher materials, giving you a single tool family that adapts to your parts, speeds, and finishes while maintaining consistent quality.
