The Carmex Carbide Tiny Tool is a dedicated face grooving solution from the Tiny Tools family, engineered for engineers, buyers, tradespeople, hobbyists, and milling enthusiasts who need clean, straight grooves on small parts. With an 8 mm minimum diameter and a 3 mm groove width, it delivers reliable, repeatable groove geometry for tight tolerances and consistent finishes.

• Straight groove geometry: Produces true straight grooves on each pass, delivering consistent seating surfaces and predictable results—unlike rounded grooves from other bar types.
• BMK solid carbide construction: Built from BMK-grade solid carbide for superior wear resistance and edge retention, helping you reach longer tool life in demanding face grooving tasks.
• Optimized sizing for 8 mm min diameter and 3 mm groove width: Specifically engineered to handle 8 mm minimum diameter stock and create 3 mm-wide grooves, enabling reliable performance with standard tool holders and straightforward setup.

With the Carmex Tiny Tool, you’ll experience faster setup, fewer reworks, and cleaner, more consistent groove finishes. Its durable carbide and precise geometry support repeatable results across parts and runs, giving you confidence to tackle tight tolerances and small-batch work in everyday machining projects.
