Hougen 11005 Hole Saw Arbor Straight Shank Pin Pilot

Product Description

The HOUGEN 11005 is a straight-shank hole saw arbor designed to drive RotaCut 11000 Series hole cutters in metalworking and fabrication applications. The arbor features a threaded shank attachment method and a steel pin pilot that centers the cutter at the start of each hole, reducing walk and improving cut accuracy. The 1/2-inch shank diameter fits standard drill chucks and magnetic drill press spindles. With three flats machined into the shank and a full-steel construction, the 11005 delivers reliable torque transfer under the load demands of annular cutter work.

This arbor is suited for use in steel fabrication shops, structural ironwork, mechanical contracting, and field service situations where RotaCut 11000 Series hole cutters are the preferred tooling. It is a direct-drive accessory intended for use in drill presses, mag drills, and hand drills equipped with a 1/2-inch chuck. Minimum cutter diameter compatibility starts at 13/16 inches, covering the core range of the RotaCut 11000 cutter line. Licensed trades and fabrication professionals working to tight hole-location tolerances will find the pin pilot design essential for repeatable results.

Designed for use with HOUGEN RotaCut 11000 Series hole cutters. Minimum tool diameter compatibility is 13/16 inches. Fits drills and mag drills with a 1/2-inch chuck.

Installation Notes

Installation is performed by threading the hole cutter onto the arbor shank until fully seated, then securing the arbor in the drill chuck with the three-flat engagement. Before mounting or dismounting the arbor, ensure the drill is powered off and unplugged or the mag drill is de-energized. Inspect the pilot pin for straightness and the threads for damage before each use. Do not exceed the drill manufacturer's rated speed for the cutter diameter in use.
