How to use
Sharpening of the drill:
Choose a hole in the head of the same diameter as the drill bit to be sharpened. Turn on the sharpener with the switch and wait for the grinding disc to reach the rated speed. Insert the drill into the hole in the head and, after hearing the grinding noise, move it forwards and backwards for 5-10 seconds, simultaneously pressing the drill with a slight force to the grinding disc. Remove the drill from the head, and then repeat the operation for the second edge of the drill bit. The edge is always closer to the outer edge of the head. The head openings have tongues limiting the rotation of the drill in the hole. This facilitates the sharpening process.
Warning! Each surface should be sharpened with the same amount of time and pressed with the same force. This will prevent uneven sharpening of the drill. After sharpening the drill, the results of the work should be evaluated. If the tip of the drill after sharpening turns blue or different from the natural color of steel, this means overheating of the surface and the needle pressure of the grinding tool should be reduced to the grinding plate during sharpening. If, after sharpening, the edges of the drill bit are not the same length, the time and sharpness of each drill bit should be corrected.
