The Carmex Carbide Tiny Tool - Face Grooving with Chip Breaker (MFR-C, BXC Grade) is a solid carbide bar engineered specifically for face grooving. It delivers straight grooves with a built-in chip breaker, helping you achieve clean, repeatable finishes on a wide range of materials. With a 5 mm minimum diameter and 1.5 mm groove width, this tool fits common machining setups and fixtures for dependable performance.
Within the Tiny Tools family, two grade options are available for this design: BXC Grade, a TiN-coated solution optimized for low cutting speeds and stainless steels (ISO P30-P50 / K25-K40); and BMK Grade, a sub-micron grade with triple PVD coating that delivers exceptional heat resistance and smooth cutting across a broad material spectrum (ISO K10-K20).
- Straight groove geometry with chip breaker: Produces true straight grooves and uses the built-in chip breaker to support clean, consistent finishes on every pass.
- BXC TiN-coated grade for low-speed cutting: Optimized for stainless steels and other tough materials at lower cutting speeds, helping reduce wear and extend tool life.
- BMK sub-micron grade with triple PVD coating: Delivers extreme heat resistance and smooth cutting for broad material compatibility, maintaining performance under demanding conditions.
This tool is designed to streamline your workflow, delivering repeatable, straight grooves with clean finishes and reduced downtime. The carbide core provides long tool life, while the TiN and triple PVD coatings resist wear and heat buildup at their intended speeds. The integrated chip breaker helps keep chips under control, enabling safer, faster cycles and a reliable path from setup to finished part.
