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

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

Great hole saw for installing 4 inch dryer vents in the metal enclosure under mobile homes for letting the moisture out from underneath the home.

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.

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

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.

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

super easy to use and works very well! Very satisfied!

good

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.

Really? Why would I want to use a pre-opened item and then find out it’s broke or stripped or dull. Who knows. Don’t send out pre opened items for real, and then think it’s ok. Just dumb. Hopefully my replacement is not pre used or open.
