The Carmex Carbide Tiny Tool – Face Grooving with Chip Breaker (MFR-C, BMK Grade) is a purpose-built solid carbide bar designed specifically for face grooving. It delivers straight grooves with clean edges and reliable chip control, giving you repeatable results across a range of materials.
With a 6 mm minimum diameter and a 2 mm groove width, this tool supports precise, controlled slotting in stainless steels and other common alloys. The BMK-grade construction features a sub-micron substrate and advanced PVD coating for outstanding heat resistance and smooth cutting, making it a dependable choice for production, workshops, and hobbyist projects.
- Straight-groove geometry with chip breaker: Produces clean, straight grooves with controlled chip flow for consistent depth and easier finishing passes.
- BMK sub-micron grade with triple PVD coating: Delivers exceptional wear resistance and high heat tolerance for long tool life and smooth cutting across a wide range of materials.
- BXC TiN coating for low-speed stainless work: Optimizes performance at lower cutting speeds on stainless steels (ISO P30-P50 / K25-K40), helping reduce built-up edge and improve finish.
This Tiny Tool supports fast, repeatable groove creation with minimized downtime and rework. Its specialized geometry and advanced coatings help you achieve consistent results, even on demanding stainless steels, making it a reliable choice for production runs, fabrication, and precise repair work.
