Carmex Carbide Tiny Tool — Face Grooving is a solid carbide bar engineered specifically for face grooving applications. It delivers true, straight grooves for precise seating and repeatable part fits, making it a dependable choice for production runs, job shops, and serious hobbyists.

With a 10 mm minimum diameter and a 3.0 mm groove width, this tool provides stable cutting performance on stainless steels and a wide range of materials. The Tiny Tools family combines two advanced grades to suit different tasks: BXC Grade with a PVD TiN coating optimized for low cutting speeds and broad stainless-steel compatibility, and BMK Grade—a sub-micron option with an advanced PVD triple coating that delivers excellent heat resistance and smooth cutting for demanding jobs.

• Straight groove geometry: Produces true straight grooves for consistent mating surfaces and predictable fits, reducing rework and finish passes.
• PVD TiN-coated BXC grade for low-speed cutting: Optimized for low cutting speeds and a wide range of stainless steels (ISO P30-P50 / K25-K40), helping extend tool life and maintain close tolerances.
• BMK grade for high-heat, smooth cutting: Sub-micron BMK with triple coating delivers excellent heat resistance and smooth cutting performance across tougher materials and longer runs.

This tiny carbide tool helps you complete grooves with confidence, improving workflow and results. The straight groove design minimizes deviation, the coatings reduce wear at the cutting edge, and the grade options let you tailor performance to the material and speed you work with. Whether you’re producing tight fits in stainless steel or tackling diverse materials, this tool supports faster setup, fewer interruptions, and consistent, high-quality finishes.
