"It's easy to retract and hold while spinning a hole saw on or off the arbor. The Irwin, Milwaukee, and Lenox hole saws all installed easily on the DeWalt arbor."
"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."
The diamond particule coating on DRILAX hole saws give superior performance and lifetime. ; Here is how you can keep the drill bit on target: a- You can make your own guide out of plywood - plastic or even a card board. You may want to invest in a Drilax Drill Bit Guide with support bearings, suction base and integrated coolant hole. FOR ALL DRILLS - HAND - PORTABLE - UPRIGHT - Shank sizes vary, maximum shank is 3/8.

"Took a while for the Quartz but the bit looks like new after cleaning it."
"I had low expectations ordering these, especially for use on Porcelain tile which is extremely hard, but they worked great!"
"The only CON is that there's no size engraved on the drill bit, so I have to match it up again my regular drill set for sizing."
"Surprisingly effective and efficient."
"Just tap the tile with a hammer and screw to get a start point and your tile bit will drill through in 10 seconds with minimal heat.I will never use these Drilax bits again the future."

"My research showed that a 6” can light might take a larger cut out, so I bought my lights first, took them out of the packaging and confirmed the size hole I needed to cut. You just set each blade to the marked size on the hole cutter measure bar (eg, I had some 6" cans that needed a 7" cut-out, and some 4" cans that needed a 5" cutout). I only had to identify the 'center' of the hole and started the pilot bit on that marking, and the hole was perfectly round, and cut in seconds where I wanted it. I highly recommend this hole cutter for the DIYer who has a home project requiring cutting perfect, holes!"
"I could cut 2 holes then had to sharpen the cutters. Since you can't buy new cutters for this model, I felt I was being forced to purchase the pro model for 15 holes."
"But most jobs you cut the same sized holes so you are not changing w each cut. One mistake I did make - I bought this for installing 6" and 8" ceiling speakers, thinking it's an 8" hole cutter , should be fine - my bad."
"The yellow rubber gasket sealed to the ceiling and the blades gave a super clean cut. The seal on the drill shaft is wonderful and the spring action is solid and precise."
