The Carmex Carbide Tiny Tool for Face Grooving (MFR - TNX Grade) is a precision solid carbide bar engineered specifically to create straight, clean grooves on the face of a part. With an 8 mm minimum diameter and a 1.5 mm groove width, it delivers consistent groove geometry that supports reliable seating and smooth downstream finishing. This tool is well-suited for engineers, machinists, and hobbyists working on precision grooving across a wide range of materials.

Two premium coating grades are available to optimize performance across materials and speeds. The BXC TiN-coated grade excels at low cutting speeds and is well-suited for stainless steels (ISO P30-P50 / K25-K40), delivering dependable results. The BMK sub-micron grade uses an advanced triple PVD coating for extremely high heat resistance and smooth cutting, offering strong general-purpose capability across materials.

• Straight-groove precision for face grooving: Designed to produce flat, accurate grooves, ensuring consistent geometry and reducing post-processing.
• Premium coatings for reliability and versatility: BXC for low-speed stainless work; BMK for high heat resistance and smooth cutting across different materials.
• Rugged dimensions for stable, repeatable cuts: 8 mm minimum diameter with a 1.5 mm groove width provides stable engagement and repeatable groove profiles in production runs.

This tool combines carbide rigidity with coating technology to extend tool life, improve finish quality, and streamline your face-grooving workflow. Its precise geometry and durable coatings help you complete grooves faster with confidence, delivering repeatable results and cleaner edges across materials.
