The Easy Grip Hole Carver is great for carving circular shaped holes in pipe insulation for inserting Pipe Insulation Support Pegs. Simply push the hollow hole punch tool into the pipe insulation, twist/turn and pull out removing a small cylinder plug of fiberglass. Insert the support peg snugly into the hole and then rotate insulation so the pipe-support is located on the bottom of the pipe hanger. Make sure that the pipe-support is holding all of the weight of the pipe to avoid insulation squishing.
