What is the best way to Sharpen Drill Bits with Angle Grinder?

When it comes to sharpening your drill bits, you have a few different methods that can be used to sharpen drill bits with angle grinder.

Step 1. Examine the Bit

If there are any nicks or chips, use a file to correct them.

Step 2. Fix the Jig & Angle Grinder

If you’re using a drill sharpening jig, make sure it is properly fixed to the angle grinder.

Step 3. Set the Grinder to the Correct Speed

The speed of the angle grinder will vary depending on the type of drill bit you are sharpening. For twist drill bits, set the grinder to its slowest speed. Set the grinder to its fastest speed for spade bits and auger bits.

Step 4. Grind the Cutting Edge of the Drill Bit

Hold the angle grinder so that the cutting edge of the drill bit is facing down and grind the edge until it is sharp. Be careful not to apply too much pressure, as this can cause the drill bit to become overheated and damaged.

Step 5. Check the Sharpness of the Drill Bit

Once you have finished grinding the edge of the drill bit, check to see if it has sharp edges. If it is not sharp, grind it some more until it is.

Step 6. Cool the Drill Bit

Once you have finished sharpening the drill bit, allow it to cool down before using it.

Step 7. Rotate & Repeat

Don’t sharpen the entire drill bit in one go. Instead, rotate it by 90 degrees and repeat the steps until the whole edge is sharp.

Step 8. Start Drilling

Once you have finished sharpening the drill bit, it is ready to use. Remember always to wear safety goggles when using a drill bit, like bits of metal can fly off and cause injury.
