Carmex Carbide Tiny Tool – Face Grooving (BMK Grade) is a solid carbide bar engineered for precise face grooving. With a 5 mm minimum diameter and a 2 mm groove width, it delivers straight, repeatable grooves that enhance seating accuracy and surface finish on a wide range of parts. This makes it a dependable choice for engineers, machinists, and hobbyists who demand consistent results.

As part of the Tiny Tools family, this BMK-grade bar uses a sub-micron carbide substrate with an advanced PVD coating to maximize performance. It’s designed as a general-purpose solution for all materials. The family also includes a BXC TiN-coated grade optimized for stainless steels at lower cutting speeds (ISO P30-P50 / K25-K40) for specialized tasks.

• Straight-groove geometry: Produces clean, straight grooves with consistent width and depth for repeatable results and smoother finishing on face-grooving operations.
• BMK-grade sub-micron carbide with triple PVD coating: Delivers extremely high heat resistance and smooth cutting, helping maintain sharpness and reduce wear across a wide range of materials (ISO K10–K20).
• Defined geometry for fast setup: The 5 mm minimum diameter and 2 mm groove width simplify alignment and ensure consistent groove dimensions across production runs.

Using this tool reduces downtime and delivers reliable results. The carbide core and advanced coatings resist wear even in demanding cuts, extending tool life and enabling longer runs between changes. The straight grooves improve seating accuracy and surface quality, while the optimized geometry and coatings help manage heat and maintain stable cutting across stainless steels and other materials.
