Introducing the Carmex Carbide Tiny Tool - Face Grooving with Chip Breaker (MFL-C, BMK Grade, 6mm Minimum Diameter x 2mm Groove Width, Left Hand). This solid carbide bar is designed specifically for face grooving, delivering straight grooves with a dedicated chip breaker for cleaner finishes and reliable performance. Its left-hand cutting geometry integrates smoothly with standard CNC setups to help you achieve precise groove control.

The BMK Grade features sub-micron carbide with an advanced PVD triple coating, delivering extremely high heat resistance and smooth cutting for maximum performance. This makes it a versatile, general‑purpose tool suitable for a wide range of materials, including stainless steels (ISO P30‑P50 / K25‑K40). The Tiny Tools family also includes BXC-grade options for low-speed stainless work, but the BMK grade on this tool prioritizes dependable heat tolerance and consistent results.

• BMK-grade coating for high heat tolerance: Sub-micron carbide with a PVD triple coating delivers durable performance and smooth cutting, helping maintain consistent groove quality under demanding conditions.
• Straight-groove geometry with chip breaker: Engineered to produce straight grooves and reduce chip buildup, resulting in cleaner finishes and fewer post-processing steps.
• Left-hand orientation with precise dimensions: Optimized for CNC setups with a 6 mm minimum diameter and 2 mm groove width, enabling precise control in tight slots and common tooling configurations.

This tool is built to deliver repeatable, high-quality grooves across materials while simplifying setup and reducing downtime. With its robust coating, precise geometry, and thoughtful sizing, you can rely on consistent performance from the first cut to the last, making it a dependable choice for engineers, machinists, and hobbyists alike.
