This machine has very little use…..How little do you ask?……….like it was used to drill four 1/16″ holes at a time in about 100 panels ……. the product never took off so here it sits. So first off we replaced all 50 bits with 5mm brad points that are on 32mm centers. Overhead are 2 adjustable pneumatic hold downs. The back fence on this one is 7′-9″ and has 3 flip stops. Adjustment of depth of bore on each head is scaled and is really easy to adjust. Each head is driven by it’s own 2HP 220V 3ph motor. Heads have a minimum of 5-1/2″ between centers and a max of 25″ from front to back of the machine with numeric read outs and adjustment on the front of the machine. This fully functional machine has been fully cleaned, checked, and is ready to work from the time you receive it. This is our guarantee to both you and your company.
