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

Carmex Carbide Tiny Tool – Face Grooving with Chip Breaker, MFR-C, BXC Grade. This solid carbide bar from the Tiny Tools family is engineered specifically for face grooving, delivering clean, straight grooves with a built-in chip breaker. It’s sized for precise control with an 8 mm minimum diameter and a 3 mm groove width.

• Precisely straight face grooves: Specifically designed for face grooving, this tool produces straight grooves for consistent dimensions and smoother mating surfaces, unlike rounded grooves from other bar types.
• Coating-grade versatility for different conditions: Two coating grades help you match your material and speed needs—BXC with PVD TiN for low cutting speeds (great for stainless steels ISO P30-P50 / K25-K40) and BMK with sub-micron grain and triple PVD coating for high heat resistance and smooth cutting across materials.
• Defined geometry for repeatable results: With an 8 mm minimum diameter and 3 mm groove width, setup is straightforward and ensures reproducible groove profiles across multiple passes.

In use, this tool supports reliable, efficient groove work across a range of stainless steels and other materials. Its carbide construction combined with selective coatings helps maintain cutting performance at lower speeds, reduces chatter, and delivers consistent results from job to job, making it a dependable choice for professional shops and serious hobbyists alike.
