Carmex Carbide Tiny Tool face grooving bars are solid carbide tools crafted for precise, straight grooves on milling or turning operations. Part of the Tiny Tools family, these bars are engineered specifically for face grooving to deliver clean bottoms and reliable performance. With a 6 mm minimum diameter and a 1 mm groove width, they enable tight control over groove size and finish.
This K20-grade tool features coating options designed to optimize performance across materials and speeds. The BMK variant uses a sub-micron grade with advanced PVD triple coating for extremely high heat resistance and smooth cutting, offering dependable performance across a wide material range. The BXC TiN-coated grade is tuned for lower cutting speeds and stainless steels, helping you maintain steady productivity on tougher stainless workpieces.
- Straight-groove geometry: Engineered to produce straight grooves with flat bottoms, ensuring consistent finishes and easier deburring on every part.
- BMK coating for high-heat, smooth cutting: Sub-micron BMK with triple PVD coating delivers excellent heat resistance and polished cutting action, supporting reliable performance across materials.
- BXC TiN coating option for low-speed stainless work: TiN-coated grade optimized for low cutting speeds and stainless steels, helping maintain stable feeds and good surface finish.
Using these Tiny Tool face grooving bars helps you achieve precise, repeatable grooves with reduced downtime thanks to long wear life and smooth operation. The combination of a compact 6 mm minimum diameter and 1 mm groove width provides tight tolerances for small features, while the dual coating options extend tool life and adaptability across production runs, making this tool a dependable choice for both professional shops and dedicated fabrication environments.
