Use this ¾” diameter hole saw and arbor to prepare the ends of 2x4 rails for use with our RailStrong connectors.  Depth of cut is 1-7/8”.

You can use our 2x4 center guide to quickly and easily locate the center of your 2x4 and plunge the hole saw to a depth of about 1-1/4”, just short of the length of the tube on the RailStrong connector.   Tap set the anchor and finish with two screws.

Arbor requires a 3/8” chuck.
