Carmex Carbide Tiny Tool - Full Radius Face Grooving - MZL - K20 Grade - 8mm Minimum Diameter x 1mm Groove Width

The Carmex Carbide Tiny Tool is a solid carbide bar engineered for face grooving applications. It creates rounded grooves with a full-radius profile, giving a smooth, continuous groove on end faces and improving mating surface results. This makes it a reliable choice for engineers, machinists, fabricators, and hobbyists who need precise, consistent grooves—especially when a rounded profile is required rather than a straight channel.

Left-hand geometry and compact sizing are built in: the tool is designed for left-hand cutting paths, with a diameter minimum of 8 mm and a groove width of 1 mm. Using MZL grade K20 solid carbide, it delivers the durability and edge retention needed for repeated passes and higher-speed machining on a range of materials.

• Full-radius face grooving capability: Delivers consistently rounded grooves that improve seal seats, face finishes, and overall part fit in a single setup.
• Premium K20 solid carbide (MZL grade): Provides lasting edge sharpness and wear resistance for reliable performance in demanding materials and higher-speed applications.
• Left-hand geometry with 8 mm minimum diameter / 1 mm groove width: Optimized for standard left-handed cutting setups and common workpiece sizes, enabling precise, repeatable grooves with minimal rework.

The Carmex Tiny Tool simplifies face-grooving workflows by delivering repeatable rounded grooves with consistent radii, reducing setup time and rework, and helping you achieve tighter tolerances on end faces. Its robust carbide composition and geometry are designed to withstand repeated use in busy workshops, providing dependable performance across jobs that require a clean, accurate groove profile.
