OpERATing inSTRUCTiOnSAdjusting the diameter:

Pivot Pin

Bottom View of measuring scales

1. This product is designed to cut a 2” to 12” hole in sheet metal, stainless sheet metal and fiber board.

Unscrew the Pivot Pin nut in a counterclock-2. wise direction. Slide the Pivot Pin assembly to the desired diameter using the built in scales underneath the unit. Tighten the Pivot Pin nut. This unit has two built in scales. One measures in 1/8” increments. The other measures in 0.25 cm increments. Adjusting the Pivot Pin to “7” on the inches scale will create a 7" hole.

3. Determine the center of the desired hole and drill a 3/16" hole. Move the unit so that the pivot point is located in the hole just drilled.

With the Hole Cutter in position, drill a second 4. hole. Start the drill and begin cutting in a clock-wise direction.

5. At halfway mark, reposition grip and cut the other half of the hole.

Replacing the drill bit:

Cutter assembly. Cap/upper bearing and

spacer positioned on the 4-3/8" x 3/16" drill bit. Be sure the set-

screw is tightened onto the flat portion of the

drill shank.

6. Unscrew the Cap and remove the cap/bearing/drill bit/spacer assembly.

Use the hex wrench to loosen the spacer set-7. screw and slide the Cap/upper bearing and spacer from the drill bit.

Slide the Cap/upper bearing and spacer onto the 8. new drill bit (this product comes with two 3/16" high-speed steel drill bits). Adjust the spacer so the hex set-screw is tightened onto the flat por-tion of the drill shank. Reinstall the Cap/bearing, spacer and drill bit assembly.
