MFR Series Solid Carbide Face Grooving Bars | Bore Mouth Arc Tools

Precise Face Grooving and Hole Mouth Arc Machining

The MFR Series solid carbide face grooving bars are specialized for machining hole mouth arcs, front R transitions, and shallow internal R features in precision components.

Equipped with a small front radius arc finishing blade, the MFR Series produces clean, precise R corners at the hole entrance and smooth internal hole transitions. This specialized geometry is essential for applications requiring high-quality curved surfaces and transitions in restricted internal areas, ensuring excellent surface quality and dimensional accuracy.
