Technical Information for WPDC Adjusting diameter of cartridge type drill Range of adjustable drill diameter 1. Single cartridge type(Drill diameter 041-059) -1.0mm 2. Dual cartridge type(Drill diameter 060-080) -5.0mm Diameter of the standard drills is provided with maximum size of standards. Ex) WPDC6570-40-6.5 Drill diameter 70.0mm Disassemble a cartridge from the holder by loosening the bolt fixed for outer cartridge. Machine after calculating the hole size on the side of the outer cartridge. Trim the sharp part after machining. Clamp the bolt for fixing cartridge without any gap in between the holder and the machined outer cartridge. Ex) How to adjust drill diameter to 066.0 machining with WPDC6570-40-8 To make the drill diameter of outer cartridge to 066.0, machine 2.0mm.
