With its PWP insertable form drill system, the company addresses the problem of high setup times. The system consists of a holder, retaining screw and an insert that is individually ground according to the customer’s drawing. During tool change-over, the insert holder stays untouched in the machine, resulting in the center height remaining unchanged. These form drills can hold the process safe within a minimum tolerance of ± 0.03 mm. To complement the PWP system, the PWP-D system offers wider inserts, achieving a maximum drill diameter of 28 mm. Both form drill systems are available in various carbide grades.
The PWP and PWP-D systems complement each other to help fill a wider need in form drilling. The PWP uses a V-style design where it mounts in the holder. The PWP-D is a square design that allows it to hold the diameter over the entire drill depth, with widths of 18, 23 or 28 mm.
