Description
Introducing the Carmex Carbide Tiny Tool - Face Grooving, MFL, Grade K20. This solid carbide bar from the Tiny Tools family is engineered specifically for face grooving tasks, delivering straight grooves that improve seating, sealing, and overall part accuracy. It’s designed for a wide audience—from engineers and buyers to tradespeople and hobbyists—providing reliable performance in a compact, easy-to-use format.
Unlike other tools that create rounded grooves, this Tiny Tool delivers true straight grooves for precise face interfaces. The result is more consistent groove geometry, reducing rework and helping parts assemble cleanly the first time.
- Straight-groove geometry for repeatable results: Produces clean, straight grooves every time, improving seating and seal integrity on mating surfaces.
- Durable solid carbide construction (Grade K20): Built to resist wear during face grooving, delivering long tool life and reliable performance in demanding workflows.
- Precisely sized for consistent setups: 6 mm minimum diameter with a 0.5 mm groove width to maintain tight tolerances across jobs and setups.
This tool helps shorten setup times, reduces the risk of groove-related defects, and supports consistent, high-quality finishes in face grooving applications. Whether in a high-volume shop or a DIY bench, it delivers dependable performance and peace of mind with every cut.
