Cobalt drill bits are most commonly used for drilling stainless steel and other metals. Diamond Drill Bits. Polycrystalline diamond (PCD) is one of the hardest tool materials. It actually consists of a layer of diamond particles bonded to a carbide support.
For drilling holes in plates, fused glass and dense, hard sea glass we recommend using a small diamond core drill. These are available in sizes from as small as 1mm. DO NOT use diamond drill bits on metal or soft wood. These materials are too soft and will cause the diamonds on your drill bit to clog up. When drilling holes in soft metals and wood use High Speed Steel drill bits (HSS) and for drilling holes in hard metals use Carbide Drill Bits.
