Here are some simple DIY tips for DRILAX drill bits:

DIY TIP 1: A high-speed tool works best, speed is important, not pressure.

DIY TIP 2: Cooling is important. Keep the hole you’re cutting constantly bathed in water. You can feed water to the drilling spot, always keeping it wet. Or you can submerge the whole piece in water in a plastic container. DO NOT SUBMERGE any electric tools.

DIY TIP 3: Use minimum pressure on the drill, just enough to let the diamond abrasive grind away the material. Using extra pressure will just damage the drill bit and not get you there any sooner.

DIY TIP 4: You may need some practice.
