Features to Consider When Buying Drill Bit for Glass

Different materials are used to make different types of drill bits. Cobalt drill bits for example are meant to drill wood, fiber glass, PVC and Aluminum. This means if you use such a drill on other type of surface apart from the specified material, you will not get the required holes or you may even break the drill bit.

When drilling, your bit may be exposed to chemicals or corrosive substances. Regular exposure to such chemicals will reduce the efficiency and robustness of your drill bit thereby making it to be insignificant in the near future. To prevent drill bits from corrosive materials, manufacturers coat bits using Black oxide-HSS. If the drill you want to buy is coated, then you can be sure it will serve you for long. It can as be well be coated with Titanium.
