The Planet Drill Press Hold Down can be used on a Drill Press or a Work Bench. Simply mount the press on your workbench and tighten the nut on the shaft.The clamping section can move up and down the shaft for major adjustments, then the lever pushes the clamping pad on the workpiece. Its very easy to use and to keep things accurate. Ideal for production runs of workpieces as the clamping section will stay at its set height on the shaft without dropping down. This hold-down can be mounted in a blind hole by using the adapter kit (DPHDKIT). SKU: DPHD1
