6. Make sure the work table is free of all loose objects and that the bit is not in contact with the workpiece.
7. Plug electrical cord into power supply and turn switch
ON. Make sure spindle rotates freely.
8. Slowly lower drill bit into workpiece. Do not force the bit, let the drill press do the work.
9. Once the hole is completed, allow the spring-loaded quill to return to its normal position. This will automatically raise the chuck and bit.
DRILLING TIPS
If the hole is large, it’s a good idea to drill a smaller pilot hole before drilling the final one. Your hole will be more accurately positioned, rounder, and the bits will last longer.
If the hole is deeper than it is wide, back off occasionally to clear the chips. When drilling metal also use a coolant.
As you increase the drill size, you may need to reduce the spindle speed.
If drilling a through hole, make sure that the bit will not drill into the table after moving through your work.
