When knock-out cutters aren’t within reach, or just too cumbersome to use, the new Hole Saw Roller Guide™ is the tool to use. To install the Roller Guide, remove the 1/4 - bit from the hole saw mandrel, and install the desired Roller Guide. Using the Hole Saw and Roller Guide Assembly, simply insert into the factory punched holes of Panel Boxes, Wireways, Junction Boxes, 4 square and 4 11/16 boxes.

With the Hole Saw Roller Guide, safely cut holes for 3/4-inch connectors and up. Each set of Hole Saw Roller Guides come with a roller guide for 1/2 inch knock-out and a 3/4 inch knock-out. The roller guides can be easily stored in a toolbox or bag or easy access and convenience.

The Hole Saw Roller Guide is a precision-tooled instrument and is Black Zinc-coated.
