The Carmex Carbide Tiny Tool is a solid carbide bar designed specifically for face grooving. It produces rounded, full-radius grooves instead of straight slots, making it ideal for parts that require a precise curved groove for seals, O-rings, and similar applications. This right-hand tool is suitable for a wide range of machining setups, helping both professionals and hobbyists achieve reliable, repeatable results.
Built with MZR-grade carbide (K20) for exceptional wear resistance and edge retention, this tool delivers consistent performance over many cycles. It features a 6 mm minimum diameter and a 1.5 mm groove width, pairing robust geometry with compatibility for common groove specifications and standard face-grooving workflows.
- Full-radius face grooving: Delivers precisely rounded grooves that improve seal seating and reduce the need for secondary finishing.
- Durable solid carbide (MZR, K20): Provides long tool life and reliable performance in demanding materials and high-speed machining.
- Precisely sized, right-hand design: 6 mm minimum diameter with a 1.5 mm groove width and right-hand cutting orientation for predictable chip flow and easy integration into existing setups.
This tool helps you accelerate production with consistent groove geometry, minimizes rework and finishing time, and supports durable performance across batches. Its exact sizing and reliable carbide construction empower you to complete face-grooving tasks with confidence, so you can focus on quality and throughput in every job.
