The Carmex Carbide Tiny Tool is a solid carbide bar designed for face grooving applications. It specializes in producing full-radius, rounded grooves rather than straight slots, delivering smooth seating surfaces and consistent groove geometry. This right-hand tool is engineered for reliable performance in tight spaces and demanding machining environments.
- Full-radius groove geometry: Delivers evenly rounded grooves for better seating, smoother finishes, and fewer secondary finishing steps.
- Durable MZR-K20 carbide construction: High wear resistance and long tool life under demanding cutting conditions, ensuring consistent results over time.
- Right-hand, compact design for small parts: Optimized for 8 mm minimum diameter and 1 mm groove width, enabling precise, repeatable grooves on small-diameter components.
Used in precision turning and milling workflows, this tool helps you achieve reliable, repeatable rounded grooves with less rework and downtime. The solid carbide composition delivers enduring edge life and stable performance, so you can trust consistent results across batches and material types. Ideal for engineers, machinists, and hobbyists seeking a compact, high-accuracy solution for tiny face-grooving tasks.
