Carmex Carbide Tiny Tool - Face Grooving with Chip Breaker - MFR-C - K20 Grade - 8mm Minimum Diameter x 3mm Groove Width

The Carmex Carbide Tiny Tool is a solid carbide bar engineered specifically for face grooving with a built-in chip breaker. Developed for the Tiny Tools family, it delivers straight grooves with clean edges, making it ideal for production runs and precision finishes on a wide range of materials.

Available in two coating and substrate options to suit your cutting conditions: BXC is a PVD TiN-coated grade optimized for low cutting speeds and compatibility with a broad range of stainless steels (ISO P30-P50 / K25-K40), while BMK is a sub-micron grade with an advanced PVD triple coating that delivers extremely high heat resistance and smooth cutting for general-purpose use across materials.

• Straight groove geometry for clean faces: Precisely formed grooves ensure uniform width and edge quality, reducing the need for post-processing.
• Coating versatility for wide material compatibility: Choose BXC TiN for low-speed stability or BMK for high-heat, high-performance applications, extending tool life and enabling consistent results.
• Rugged carbide with chip breaker: Built to endure demanding grooves with controlled chip formation, promoting smoother cuts and less downtime due to chip clogging.

This tool’s 8 mm minimum diameter and 3 mm groove width provide stable engagement for repeatable, reliable grooves. By combining a robust carbide substrate with tailored coatings and a dedicated chip-breaker design, it helps your workflows move faster—from setup to finished part—while delivering consistent, high-quality groove finishes.
