Tap Holders - Model AR

Adjustable releasing tap holders are used in screw machines, turret lathes, CNC lathes, and reversing spindle automatic screw machines. The tap is mounted in the tool holder directly or in a bushing; the holder assembly is adjustable to accurately align the tap with the workpiece. After it is started in the workpiece, the tap leads itself to a preset depth and draws the tool holder out of drive engagement with the tool head assembly, which permits the holder to rotate freely with the workpiece. Spindle reversal re- engages the tool holder, withdrawing the tap from the hole, and returns the tool holder to its original position. The tool is easily changed from right to left-handed operation with a simple adjustment.
