High pressure only will add up the heat in diamond drill bits the added heat will affect your drill bits and in some cases the glasses too. That doesn’t mean you should give high pressure anyway. It is essential to provide enough pressure to the drills so that the diamonds drill bits not slipping away from the target. The hand pressure you give on the glass while drilling is essential. Once the drill bits started penetrating the glass, increase the speed slowly and finish the job correctly. Use the quality drill bits for glass along with these drill press machines at the low speed first. I have listed here the 5-Speed drill press machines priced under $200.
