About this deal

Spurs First: Start with the spurs of the drill before moving to the point. It should only take a few strokes to properly sharpen the spurs when kept at the correct angle. The same is true when using a grinder.

The answer is yes, but the process can be a little involved. You may want a professional to sharpen your Brad point drill bits if you do not have the experience or proper tools to do the job. To sharpen the bits, you will need to customize your grinding wheel, or you may use one or more of the following manual tools.

Coming to metal bits, you will notice an angle at the tip, and they are mainly made from HSS material. Then, you will find golden or coppery colors as the dominant ones in the market.

High-speed steel (HSS) is a form of tool steel; HSS bits are hard and much more resistant to heat than high-carbon steel. They can be used to drill metal, hardwood, and most other materials at greater cutting speeds than carbon-steel bits, and have largely replaced carbon steels. Before starting to drill our way into the materials, we need to buy the proper bits for the task. The market has plenty of them, and sometimes it is difficult to figure out which one works better for you.

It’s also crucial that you use a drill bit designed for plastic, given how difficult it can be to create a clean hole using any other type of bit.
