Description
Version:
With left-hand helix 7 − 8° and long taper lead, more than 1/5 of the cutting length. An even number of teeth with irregular spacing for accurately round holes, free of chatter. The cylindrical ground chamfer on the plain cutting section smooths the hole and guides the reamer.
Application:
For through holes (not for blind holes). Also very suitable for interrupted holes.
