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

There's a MAJOR design flaw in the provided adapter nuts included with the quick change. If you're 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.

This is a replacement. I already have a bunch of the hole saws and just haven't had time to investigate inter-compatibility of hole saws and mandrels. If I had then I wouldn't 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.

A little difficult to connect and disconnect to hole saw, but holds in place well and is great for pushing out the material that get stuck in hole saw when making cuts. This seller had the best price and shipping was fast.

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 didn't 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 I'm hoping it was just a defect in the pilot bit, I'm gonna buy another pilot bit and hope for the best

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.

great tool, makes moving from one hole saw to another with ease at first. how after a few uses it seems to lock up somewhat, making it difficult to actually lock the hole saw onto this. I can still make it work, however with the amount of time I struggle removing the hole saw to use another one I could properly just change the whole thing out faster then trying to get this tool to work like it first did.

MUCH CHEAPER THAN THE DIABLO EQUIVALENT, BUT VERY DURABLE AND WELL-ENGINEERED.JUST AS GOOD [OR BETTER, GIVEN THE QUICK-CHANGE ABILITY], THAN THE DIABLO SAW ARBORS.

When I ordered the hole saw I didn't 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.

El producto llegó abierto pero completo, lo compré para utilizar las broca sierra de la marca, también incluye adaptadores para utilizar las de otras marcas, funciona bastante bien

Very good and easy to work with and fast to change holesaw

Perfect
