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

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.

Simple to use and with the quick disconnect it makes swapping out different sizes a snap.

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.

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.

The drill bit that came with the hole saw mandrel broke the first time I used it...with the first minute! I am checking with Amazon for a free replacement. It should not break that quickly or easily. I think it was defective.

So far I really like this design VERY fast!!!

This tool served the purpose for which it was purchased. Great tool, great value, great overall.

This tool gives me greater flexibility.

This is a replacement. I already have a bunch of the hole saws and just havent had time to investigate inter-compatibility of hole saws and mandrels. If I had then I wouldnt have bought this replacement. The last one only lasted through 4.5 doors before bearings literally started popping out of it and it stopped retainng both hole saw and drill. I was able to finish the last door only by setting the drill in place carefully and relying on pressure to keep everything held together.

The hole saw powered right thru the 2 thick walnut without the cutout sticking inside the blade. I have made thousands of items and am not easily impressed by tools. Good job Freud!
