HOLE SAW IS THREADED...... SHOULDN'T COME LOOSE UNLESS YOU HAVE "JAMMED" IT AND USED REVERSE ON YOUR DRILL. IF YOUR HOLE SAW DOESN'T FIT UNTO THE THREADS YOU MAY NEED THE VARIETY THAT HAS 2 "PINS" THAT FIT INTO THE HOLE SAW. THIS BIT IS FOR USE WITH UP 1 1/8" BITS, WITH THE EXTRA FITTING THREADED ON IT WILL WORK EXCELLENTLY WITH 1 3/8" BITS. LARGER YOU NEED THE "PINNED" VARIETY.

Worked nicely on the small diameter hole sizes and the adapter allowed me to use it on the larger sizes. The largest I used it on was 1 3/8". Stayed tight. Good price.

Fits multiple Size Hole Saws
This arbor conveniently comes with an adapter bushing to permit its use with more than one size hole Saw. Adjustment is provided for the relative "stick out" of the pilot drill (depending upon the depth of the hole saw used. The hex shaped shaft provides for a good "grip" in the drill motor chuck, to prevent slippage under load. This arbor was used with the adapter and a Klein hole saw.

good tool
sweet arbor set up the pilot bit is good and sharp it starts the hole without sliding off the mark. It also has a hex so that it is easier to hold while changing hole saw sizes and holds well in the drill chuck without slippage. There is a set screw holding the bit in place but it also makes it easy when you need to remove it for sharpening or replacement. It also comes with a adapter to fit larger hole saws.

Rugged and Affordable Hole Saw Arbor (Saw Not Included)
This arbor comes with a threaded 5/8" adapter that is used with hole saws 1-3/8" (35 mm) and larger in diameter. A different arbor catalog number 31906 with pins is recommended for hole saws 2" (51 mm) and larger in diameter. Hole saws are engaged by screwing them onto the threaded portion of the arbor. The pilot drill bit included with this arbor is 1/4" in diameter and is secured in place with a 1/4" diameter set screw that requires a 5/32" or 4 mm size Allen wrench. The drill shank on this arbor is 0.370" hex shaped to provide positive engagement in a drill chuck. The manufacturer applied a sticker external to the plastic packaging with a picture of a drill 1/2" (13 mm) as the suggested drill to use with the arbor. A 1/2" drill is easier to use and control then some 3/8" drills when boring large diameter holes because a 1/2" drill can develop much higher torque at low RPM unlike some 3/8" drills and also rotates at a lower RPM then 3/8" drills.
