Using the mortise case as a guide, adjust the position of the depth clamp on the bit shank to determine the depth of cut.
Be sure to bring a shop vacuum to collect the debris, keeping a clean work area.
Begin cutting the mortise pocket at the bottom. Drill the first hole. This way, the debris falls down into a hole that has already been drilled and does not clog the hole being drilled.
After every inch drilled, back out the bit to clear the chips. Do not attempt to drill any hole to depth all at once. Use a moderate drill speed of 350 to 500 rpm.
Drill each additional hole directly above the previously drilled hole.
For this installation six holes were drilled, leaving some webbing between each hole. Remove the webbing after the six holes have been drilled.
The mortising bit is also designed to remove the material between the drilled holes.
Before drilling any of the lock function holes, make sure the mortise bit is out of the pocket. Once the mortise pocket has been drilled to size, drill the lock function holes.
HIT-66-282 templates provide the locations for the lock hardware. Drill the holes for the spindles, thru bolts, mortise lock cylinder and thumbturn. Once drilled, remove the tool.
To finish the mortise pocket, use an 8” wood rasp to smooth the walls and remove any excess debris. Slide the mortise case into the pocket. Check to be certain it slides in smoothly and the location holes align with the lock.
