how to sharpen drill bits with a bench grinder
Nothing new to buy! There is very little set-up time when using a grinder for sharpening drill bits. Just put on eye protection, turn the machine on, and start sharpening. A bench grinder can also be used for scissors, lawnmower blade sharpening, and putting a sharp edge on other garden tools.
Step Two: Sharpening and Cooling. In order to correctly sharpen the drill bit the grinder will need to be set at t a slow speed. Place the bit against the base of the wheel so that the sloped side touches the cutter. This should be near a 60 degree angle for most bits. Do not let the tip of the bit touch the grinder.
