The RF100 Speed is available in two versions. The regular length 2xD version is provided with a straight cutting design for slotting, roughing and finishing. Additionally, the RF100 Speed is offered in a 3xD cut length, where chipbreakers are spaced along the flute length to reduce chip size during long machining cycles.
The face geometry features a 48° helix angle and unequal flute spacing. Such a high helix angle would have potentially weakened the wedge angle, so Guhring has extended the land angle to help retain edge strength.
Both the standard length and extra-long series are available in 3, 4, 5, 6, 8, 10, 12, 16 and 20 mm diameters.
