912 Hole Saw 1-3/8" & Mandrel

The 912 Hole Saw & Mandrel cuts a 1-3/8" diameter hole in sheetrock up to 1-1/2" thick material. The 912 Hole Saw & Mandrel is used in the field for installation preparation of the 200 Hanger. A common obstacle is running into steel studs because the Bi-Metal will cut through a steel stud; however, we recommend cutting the locking arms off the back of the 200 Hanger, which leaves a 5/8" thick hanger that can be screwed directly to the steel studs. The same method works well with double sheetrock. Application The 912 Hole Saw & Mandrel cuts a 1-3/8" diameter hole in sheetrock up to 1-1/2" thick material.
