Notice: We have provided the manufacturer's recommended Speeds & Feeds Guidelines for our Raptor Dovetail Cutters. Raptor suggests that machinists consider their experience, their machining style (conservative or aggressive) as well as the type of machine being used, the material type being cut, and then make necessary adjustments using their best judgement taking into consideration all of the variables in the machining process.
