Introducing the Carmex Carbide Tiny Tool - Face Grooving with Chip Breaker (MFR-C BMK Grade). This solid carbide bar is engineered specifically for face grooving, delivering straight grooves with reliable chip control in tight spaces. With a 5 mm minimum diameter and a 1.5 mm groove width, it provides precise, repeatable results for small-diameter work.
Two high-performance grades are available in this Tiny Tools family: BXC and BMK. The BXC grade features a PVD TiN coating optimized for low cutting speeds and pairs well with a wide range of stainless steels (ISO P30-P50 / K25-K40). The BMK grade is a sub-micron material with an advanced PVD triple coating, offering exceptional heat resistance for maximum performance and a smooth cutting experience across materials. This makes it a versatile, general-purpose option when you need consistent results across applications.
- Straight-groove geometry with chip breaker: Enables precise, flat grooves with controlled chip formation for predictable results and reduced post-processing.
- BXC TiN-coated grade for low-speed machining: Optimized friction and performance at lower cutting speeds, improving tool life while handling stainless steels and similar alloys.
- BMK sub-micron grade with triple PVD coating: Delivers outstanding heat resistance and smooth cuts, providing reliable performance across a broad range of materials.
This tool is designed to streamline production workflows: it minimizes rework by delivering clean, repeatable grooves, reduces downtime with durable coatings, and supports steady performance from first pass to finish. Trustworthy geometry, compatible coatings, and robust construction help you hit tight tolerances with confidence, making it a dependable choice for both pro shops and busy manufacturing environments.
