For shops doing a high volume of Switch Grip™ installation, the Reamer End Mill has 8 cutting edges ensuring optimum drill and fit for easy Outer Sleeve installation. Because of the deeper drill depth of the Outer Sleeve and the dense core materials/designs used in many high tech bowling balls, a traditional 1 ½” drill may drift off center, more so toward the bottom of hole. This off center cut will make the Outer Sleeve more difficult to fit properly at bottom because it is tight. Keep in mind the Outer Sleeve is designed to be a press fit and should never be forced into position. If the Outer Sleeve is forced into hole, the Inner Sleeve will not fit properly and be very difficult to insert and remove. The Reamer End Mill ensures a better fit from top to bottom of hole.
Available: 1 1/2″ Straight Shank with Auto Stopper.
