Drilling
Here are a few tips to prevent accidents and to improve the quality of the drill holes.
Lubrication
When drill non-wood materials, such as metal or plastic, use the correct type of lubricant to prevent
overheating.
Feed Rate and Pressure
In most cases, it’s best to keep the feed rate and pressure consistent when drilling a hole. The optimal
feed rate and pressure depend on the drill bits and material types. Apply proper pressure and control the
feed rate to avoid overheating, as this can dull the drill bit quickly and can cause the materials to catch
fire. Replace a drill bit when it becomes dull, and do not force it to work.
Drilling Large Holes
When using very large drill bits, a dent made by a center punch may not keep the drill bit from wandering.
Drilling a pilot hole can mitigate this issue.
Dust/Debris Removal
When drilling deep or big holes, raise the drill bit often to clear the debris. This helps reducing friction and
thus extend the life of the drill bit and the motor.
Dust produced by drilling is a health hazard. Using a dust collector to remove the dust and debris to reduce
health risks. Wear a good dust mask to further reduce dust inhale.
Stopping the Drill Bit
NEVER use your hand or any external objects to stop the spinning drill bit. Allow the drill press to slow
down to a complete stop before removing the workpiece and the drill bit.
