"When I first pulled it out of the packaging, I was afraid that it wouldn't fit my rechargeable drill but it fit just fine."
"Nice adjustability of the center drill bit inside the circle saw component."
"Thus there is no way to reliably order a Dewalt arbor for a 3/8" drill to fit a hole saw with a 5/8"-18 engagement thread."
"As this was my first hole saw and I didn't already have the mandrel portion, I ordered the combo of 2"-dia (2"-max-depth) hole saw and 7/16"-shank mandrel [DW1803] recommended by Amazon. The 2 pegs in the silver-colored locking collar snap into one of the 2 opposing-hole pairs in the bottom of any Dewalt hole saw to hold the cutting end in place, but at the same time prevent the hole saw from locking itself onto the mandrel under the torque of drilling. Just slip the mandrel shank into your drill chuck & tighten down, then with the drill positioned the way you'll be using it (butt end against your belly), use one hand to pull the locking collar toward you as far as you can, and the other hand to screw the barrel end of the hole saw onto the threaded part of the mandrel. You should end up such that tightening the barrel part all the way down leaves the locking pins misaligned with both of the crosswise pairs of receiving holes, at which point you unscrew the barrel just enough to allow the pins to snap into the nearest hole pair. Lastly, I used the centering hole left in the tenon by the pilot bit of the hole-saw mandrel by drilling a same-1/4"-diameter hole the rest of the way through the center of the mortise (which in my case only went 1.5" sideways into a 4x4, roughly halfway through) and then using a lag screw started from the opposite side of the 4x4 to firmly fasten everything together."
"This quick change Mandrel is required when using other style hole cutting saw blades."
"I purchased (http://www.amazon.com/DEWALT-D180034-8-Inch-Standard-Bi-Metal/dp/B00005LEZB/ref=sr_1_1?ie=UTF8&qid=1419370355&sr=8-1&keywords=DEWALT+D180034+2-1%2F8-Inch+Standard+Bi-Metal+Hole+Saw) as well from Amazon which is a great product."
"The locking pins will even match up on my other hole saws so...I am not sure if this is by design or by accident but the end result is they fit and it really makes your hole saw fit good and snug."
"Mostly, I want to address the 1-star reviews—those who are breaking the pilot bit are doing so because they're not pre-drilling a smaller pilot hole first."

"Surprisingly effective and efficient."

"sharp and well made... very hard to controll but not fault of saw its just bvery difficult to hold exactly vertical !!"
"The steel is pretty strong, but won't hold up to a super powerful drill motor if you go too fast."
"Having a corded electric drill would probably be best, but i was able to cut four holes with my cordless dewalt drill."
"I have literally built 15 sets of cornhole boards with this hole saw."
"My first cut, the center post drill bit that guides the say broke clean off!!!"
"I didn't like this hole saw because it is very flimsy."
"I was able to use the hole saw to still make guidelines for the jigsaw cuts on some cornhole boards, so I finished the job... just not getting the value from this purchase that I'd expected."
"I was able to cut one hole in 1/4" hardboard using a drill press, and the result was a jagged hole, lots of vibration, and I was concerned that it might break."
