Clean the Drill Bit

Before sharpening a masonry drill bit, it must be thoroughly cleaned. Remove any material buildup on the drill bit using a wire brush. Use a cloth to wipe away any remaining residue. It is important to ensure the drill bit is free from any dirt or debris before sharpening.

Use a File to Sharpen the Bit

The most straightforward way to sharpen a masonry drill bit is to use a file. Hold the drill bit firmly and use a flat file to sharpen each of the four cutting edges. Make sure to evenly sharpen each of the cutting edges, angling the file in the same direction as the cutting edge. Once the edges are sharpened, use a round file to sharpen the tip of the drill bit.

Use a Bench Grinder to Sharpen the Bit

Using a bench grinder is a more efficient way to sharpen a masonry drill bit. With the drill bit securely held in a vice, turn on the grinder and slowly run the drill bit against the grinder wheel. Make sure to evenly sharpen each of the four cutting edges, and then sharpen the tip of the drill bit. Finally, use a wire brush to remove any residue.
