The Carmex Carbide Tiny Tool for Face Grooving (MFL) is a solid carbide bar designed specifically for face grooving applications. Part of the Tiny Tools family, it delivers true straight grooves, a key advantage when you need clean, precise faces. The tool supports a minimum diameter of 5 mm and creates grooves 1.5 mm wide, providing a compact, reliable option for precision groove work.
Built for engineers, machinists, and hobbyists alike, this tool combines durable carbide performance with straightforward setup. It keeps workflows predictable even in repetitive production, helping you finish parts with consistent groove geometry.
- Straight groove geometry: Produces true straight grooves on the face, ensuring consistent groove width of 1.5 mm and flat seating surfaces. This contrasts with rounded grooves from other bar designs.
- Solid carbide, Grade K20 durability: Constructed from high-hardness K20 carbide for long tool life, excellent wear resistance, and sustained cutting performance under common shop temperatures.
- Optimized Tiny Tools design for stable cuts: Engineered to minimize chatter, improve rigidity, and deliver reliable, repeatable grooves in single or multi-pass operations. Also designed for quick, hassle-free setup with standard holders.
With these features, the Carmex Tiny Tool for Face Grooving helps you achieve precise, repeatable grooves with fewer passes and less rework. The straight-groove geometry improves seating accuracy and surface fit, while the durable K20 carbide reduces tool changes and downtime. Overall, you gain consistent results, improved workflow efficiency, and greater confidence in finished parts across a range of machining tasks.
