Aligning and Sharpening Masonry Drill Bits
To sharpen a masonry bit, you do not turn the Chuck, instead
you use a plunging motion. Insert the Chuck until it touches the
wheel, remove, and repeat on the other side.
Plunge until sharp
Align the White Triangle on the Chuck with the Cam Pin on the
machine. Plunge the Chuck into the Sharpening Port until it
contacts the Sharpening Wheel. Remove the Chuck and rotate
one half-turn to the opposite White Triangle. Plunge the Chuck
into the Sharpening Port again to sharpen the other side of the
carbide insert. Start with four plunges. Inspect the bit. Then
sharpen more if needed.
