Hougen Holcutter 14244 Hole Cutter

The Holcutters, are not hole saws. Theyre precision ground, heat treated tools that easily cut thru the stock rather than ripping, tearing and pushing thru as do typical hole saws. They can produce holes three times faster and cleaner than hole saws in sheet metal and have dramatically extend tool life, too. All sizes have a "shoulder" to prevent plunge-thru, which is especially useful when drilling into live electrical boxes.

• Feature the patented quad-lead thread system for faster cutter changes
• Lasts 3X longer and cuts 10X faster than hole saws or twist drills
