Are All Drill Bits The Same?

Companies nowadays have introduced universal drill bits that can be used for various surfaces such as concrete, brick or wood, and are available at many hardware stores. However, these are not 100% universal, since these drill bits can be inappropriate for surfaces such as glass or ceramics. So, unless the surface is not that fragile, the drill bits don’t need a separate drill for different surfaces. However, high-quality drill bits are expensive and need to be taken care of because they are an investment and can wear out quickly if they are not maintained. 

How to Choose Drill Bits

When finding out the correct drill bits, you essentially want to look for the speed and the time-saving aspect of the drill bit, so that you penetrate through the wall easily. If you are a novice at drilling, then this guide might be helpful for you to figure out how to spot the drill bit that aligns with your preferences.

Wood Drill Bits

These can be recognized by their sharp, pointed end and spurs on the sides. These are good for carving wood. Steel bits work well with softwood varieties, while a titanium-coated wood drill bit is the most durable one. Overall, these bits are really nifty for and common.
