DRILL PRESS SPEED CHART

Lubricate drill with oil when cutting steel 1/8″ or thicker. Use center punch on all holes to prevent drill from wandering.

Good all-around bit.
These cut more quickly than brad points
and twist drills.

Raise 1/4″ and smaller bits often to clear
shavings and prevent heat build-up.

Raise 1/4-3/8″ bits often to clear shavings
and prevent heat build-up.
Make several shallow passes with larger
bits; allow bit to cool between passes.

Wear safety goggles. Use drill press
only. Do not apply excessive pressure.
Lubricate with water while drilling.
Reduce quill pressure when bit tip
emerges from back side.

Do not use with brass or aluminum
thicker than 1/16″.
Avoid dense hardwoods such as hard
maple.

Smaller sizes also available; use Forstner speeds.

Clamp work to table to improve quality
of hole.

Best bit for acrylic. Clamp work securely.

Ideal for deep holes and end-grain drilling.

Drill one side, flip material over, place
center bit in its hole, and resume cut.

Cuts cleaner than traditional countersinks.

Raise and lower frequently for quicker
cutting.

Clear twist drill often.

Clear bit often to prevent heat build-up.

Cut to full depth so bit chamfers plug.

Avoid load-up and overheating.
Decrease air pressure for fine contours.

Adhesive-backed discs work best.

Use light pressure.

Hold work firmly.

Use 6″ or smaller wheel.
