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

Used the product in a DIY project. Works well, built well.

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

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.

I have been waiting for this part, I bought the hole saw it self from Home Depot and had to wait a week for the shipping. After I recieved it and saw it didnt come with the pilot and attachment bit, I looked for and bought it here, as soon as I got home from work I started using it. I loved how easy it was to put on and off, but it snapped while drilling the first pilot hole. I gave it 3 stars because Im hoping it was just a defect in the pilot bit, Im gonna buy another pilot bit and hope for the best

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.

good

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.

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.

Very heavy duty.
