OPERATIONS
BEFORE EACH USE
CORRECTLY SHARPENED BITS
Your bit is correctly sharpened when it has the following characteristics.
• A sharp point in the center of the bit.
• Two sharp and equal cutting edges
• Two trailing edges that are slightly lower than the cutting edges.
ADJUSTING THE GRINDING STONE
1. Turn the grinding stone height
adjustment knob clockwise to
raise the stone.
• This will give you a more
aggressive cutting action. This is
also useful when you are
working with short bits.
2. Lower the stone by turning the
adjusting knob anti-clockwise.
• This will produce a finer ground
edge, though it will take longer and require more repetitions.
