Drill presses make drilling easier and faster. Drill presses employ a few key components such as a specially-designed drill, a stand and a clamp to secure the drill to the stand. A lever handle is used to draw the drill component down onto a workpiece. Drill presses allow precise drilling through beach stones and other materials.
You can drill through hard materials including beach stones with diamond-tipped drill bits. Diamond gemstones are the hardest material on Earth. Drill bits with diamond coatings, however, though very strong and durable, can be brittle. Diamond-tipped drill bits can break and the coatings can wear off if they are used roughly or improperly. You can find drill bits in the same wide range of sizes as most other types of drill bits.
Using water during the drilling process can be very beneficial. Water drawn between a drill bit and a workpiece helps keep temperatures down and dust production to a minimum. The easiest way to promote water flow through drill bit and workpiece is to do the drilling under water. You can place a beach stone in a dish, submerse it in water and drill through it with a drill press. Diamond-tipped drill bits work very well under water. While drilling through a beach stone, the drill operator should draw the bit out of the workpiece several times to allow water through. Certain diamond-tipped drill bit models feature shanks that promote better water flow through drill bit and workpiece.
Drilling a clean hole through beach stones can be a difficult process. The best way to drill through beach stones is to drill a pilot hole first, change to a larger bit and enlarge the hole slowly. This puts less pressure on the stones and helps prevent them from breaking or chipping during the drilling process. You should hold or secure beach stones firmly while drilling holes through them with drill presses. In general, the harder the workpiece, the faster the drill rotation speed required to drill through the workpiece.
