Operation drilling See Figure 20.  Using a clamping device, secure the workpiece to the worktable. To protect the top surface of the workpiece, use a piece of scrap wood between the vise and the workpiece.  Select the proper drill bit based on the hole size desired. For large holes, drill a pilot hole first, using a smaller diameter bit.  Select and set the recommended spindle speed. Refer to Changing Speeds in the Adjustments section of this manual.  Set table assembly to desired height. Refer to Adjusting Table Height in the Adjustments section of this manual.  If desired, set feed shaft at desired spindle depth. Refer to Adjusting Depth Gauge in the Adjustments section of this manual.  Make sure the work table is free of all loose objects and the bit is not in contact with the workpiece.  Plug electrical cord into power supply and turn switch ON. Make sure spindle rotates freely.  Slowly lower drill bit into workpiece. Do not force the bit; let the drill press do the work.  Once the hole is completed, allow the spindle to return to its normal position. This will automatically raise the chuck and bit. DRILLING TIPS  If a large hole is needed, 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, lubricate the bit with oil to improve drilling action and increase bit life.  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 the workpiece. clamp Fig. 20 20
