sharpening (see 'Troubleshooting'). Consider adjusting the Grinding
Wheel (8) height, if the sharpening result is not satisfactory (see
'Adjusting the grinding wheel')
7. Repeat steps 1-6 to sharpen the other side of the bit. Use the same
technique, downward pressure and amount of time to achieve an even
sharpening result
8. Examine the drill bit and ensure both cutting edges are evenly
proportioned and shaped, that the point is centred, and that the trailing
edge is free of burrs (Fig. B)
9. Repeat steps 1-8 as required
Note: If sharpening a broken off or very dull bit, use a bench grinder first to
roughly shape the drill bit.
