Freud DHSAR375 Diablo Hole Saw 3/8 Mandrel Quick Change w/Pilot

Outstanding, works great, even with my old saw parts/blades. Incredible invention. If you have a hole saw, add this to the collection. Will USN Ret.

This works great and easy swapping to other brand of hole saws too

The fit of the pilot drill in the mandrel allows way too much lateral play.

Works great. So easy to set up vs a typical hole saw set.

Theres a MAJOR design flaw in the provided adapter nuts included with the quick change. If youre using the quick change with Freud/Diablo hole saws that are meant for it, in other words the hole saw arbor nut is welded to the hole saw, these are a great tool to have and work great. HOWEVER, if you use the provide adapter nuts on older hole saws, if for any reason you need to reverse the drill (since there are no pins holding the hold saw in place) the adapter nut just simply unscrews leaving your hole saw stuck in place. Additionally, if you use a larger hole saw with the adapter nut, you MUST NOT release the drill trigger once you start drilling your pilot hole because the flywheel motion of the hole saw weight allows the hole saw to unscrew rapidly and fly off the adapter nut if you stop the drill, potentially CREATING A VERY DANGEROUS SITUATION. This flaw SHOULD BE ADDRESSED BY FREUD by somehow adding locking pins to this system.

If you need to change hole saws often this is a great tool.

Had the mandrel for my Diablo hole saw kit break and just needed to replace that. This works great and was not only a perfect fit for the various hole saws, but also was an exact fit in the case they came in.

Well made and good value but only given 3 stars as mandrel adaptors did not fit my UK hole saws.

When I ordered the hole saw I didnt realize that it took a special MANDREL and so I ordered this one and it worked great. Seems to be more secure than the standard threaded style.

Bought this in combination with the Freud DHS2500 Diablo High Performance Hole Saw and am really pleased with the feature. It has inspired me to replace my old set of hole saws with the Freud Diablo brand.
