The HSN-501i heavy duty hole saw notcher is an upgraded version of the standard HSN-501. Built around a heavy duty 1/2 inch thick aluminum base plate with a 1 inch diameter shaft supported on sealed ball bearings, this is one heavy-duty notcher! This notcher will handle 3/4 through 2 inch diameter tubing at angles up to 60 degrees, and uses regular bi-metal hole saws.
The HSN-501i can be used in a drill press or attached to a table and used with a standard 1/2 inch drive hand drill. This tube and pipe notcher also has an adjustable vise for offset notches - a feature not found on other drill press mounted notchers!
