The Carmex Carbide Tiny Tool - Face Grooving - MFL - Grade K20 - 8mm Minimum Diameter x 1mm Groove Width is a solid carbide bar engineered for precise face grooving. Part of the Tiny Tools family, it’s designed to deliver straight grooves with consistent edges, making it ideal for machinists, toolmakers, and hobbyists who value clean, repeatable results on metals and engineered materials.

With an 8mm minimum diameter and a 1mm groove width, it maintains stable cutting geometry for predictable results. The MFL designation paired with Grade K20 carbide delivers wear resistance and long tool life in demanding grooving tasks.

• Straight groove geometry: Engineered to cut straight grooves on the face, delivering clean edges and predictable paths for reliable fits.
• Durable K20 solid carbide: High wear resistance and long tool life under typical face grooving conditions, reducing replacement frequency.
• Optimized 8 mm min diameter x 1 mm groove width: Precisely sized to maintain cutting stability and consistent groove width across projects.

This tool helps you complete face grooving tasks with confidence, delivering consistent grooves that mate cleanly with downstream components. By combining rigid carbide with a geometry tailored for straight grooves, it reduces chatter, improves surface quality, and speeds setup and finishing work. With the Tiny Tools lineage, you gain a reliable, familiar performance that supports both professional production environments and personal workshops.
