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

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

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

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.

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.

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

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

Quick change is the bomb! The piece ejector works great too. Item:Freud DHSAR375 Diablo Hole Saw 3/8 Mandrel Quick Change w/Pilot

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

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