General Drilling Instructions
1. using a clamping device, secure the work piece to the worktable. If drilling a through hole, place a
piece of backup material (wood, plywood, etc.) on the table underneath the work piece to prevent
splintering on the underside of the work piece. To protect the top surface of the work piece, use a
piece of scrap wood between the vise and the work piece.
2 Select the proper drill bit based on the hole size desired. for large holes, drill a pilot hole first, using
a smaller size bit.
3 Select and set the recommended spindle speed. Refer to FIG 14.
4. Set table assembly to desired height.
5. If desired, set feed shaft at desired spindle depth. Refer to Set Drill Depth.
6, Make sure the work table is free of all loose objects and the bit is not in contact with the work
piece.
7. Plug in power supply and turn switch ON. Make sure spindle rotates freely.
8. Slowly lower drill bit into work piece. Do not force the bit; let the drill press do the work.
9. Once the hole is completed, allow the spindle to return to its normal position.

Drilling Tips
1. 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.
2. If the hole is deeper than it is wide, back off occasionally to clear the chips.
3. When drilling metal, lubricate the bit with oil to improve drilling action and increase bit life.
4. Smaller drill bits require greater speed than large drill bits. Softer materials require greater speed
than harder materials.
5. If drilling a through hole, make sure place a piece of backup material (wood, plywood, etc.) on the
table underneath the work piece to prevent splintering on the underside of the work piece.
