The Carmex Carbide Tiny Tool – Face Grooving with Chip Breaker, MFL-C, K20 Grade, is a solid carbide bar engineered specifically for precision face grooving. With an 8 mm minimum diameter and a 3 mm groove width in a left-hand configuration, it delivers clean, straight grooves for reliable seating and consistent part fit. Designed for a wide range of shop setups, it’s ideally suited for engineers, machinists, and hobbyists who demand repeatable results.
Part of the Tiny Tools family, this tool combines tough carbide substrate with coating options to balance wear resistance and heat tolerance across tough materials like stainless steel, helping you maintain smooth cutting performance over longer runs.

• Straight-groove geometry: Engineered to produce straight grooves rather than rounded profiles, ensuring consistent fit and reliable sealing in face-grooving applications.
• Chip-breaker design: Integrated chip breaker minimizes chip buildup and heat, improving surface finish and reducing tool wear and downtime.
• Coated, high-performance carbide options: Available with BXC PVD TiN coating for low-speed stainless cutting or BMK sub-micron grade with triple coating for maximum heat resistance, all on a K20 substrate for dependable durability.

With its precise straight-groove capability and intelligent coating options, this tool helps you complete grooves faster with fewer reworks, reduces downtime from chip buildup, and delivers consistent results across a range of materials. The left-hand configuration and robust carbide build provide reliable performance in production and repair environments, making it a dependable choice for demanding face-grooving tasks.
