User questions & answers

Question:	The description is false. Why does it say recommended for 6 inch fixtures? The biggest size the kit has is 2 and a half
Answer:	It will fit like a glove
Question:	Will this work on stucco
Answer:	Yes.
Question:	Does this fit a 3/8ths chuck (Black & Decker Matrix drill
Answer:	Definitely 8-1/4”, not 2”. It works great on wood and dry wall. I used it to drill an 8-1/4” hole on the wall to install my kitchen hood with 8” duct.
Question:	Can i used this to cut holes in hdpe sheets
Answer:	don't know. bought to cut through stucco. worked good.
Question:	What is the diameter of the cutouts this produces? looking for one to make plywood cutouts 8" in diameter to fit into pvc pipe
Answer:	It will, but be aware that you will need a matching arbor. I find it easier to cut tile with a diamond core bit, which is also available from Amazon.
Question:	Repeating the same question that someone posted before, but was never answered...will a starrett (#a-10) arbor fit this ruko 8-1/4" hole saw
Answer:	1/2" arbor that you can get at any hardware store but you need to. Ha get the pilot bit to a masonary one.
Question:	Is this 8 and 1/4 inch diameter? Picture looks like it’s 2 inches
Answer:	No pilot, no arbor. Just the holesaw. They last longer than any other holesaw I have used in the past, especially when notching Chromemoly tubing.

User questions & answers

Question:	Will these cut through HardiePlank fiber cement siding
Answer:	They are made in Taiwan.
Question:	is it solid carbide or only the teeth
Answer:	I think they will work fine as long as you use plenty of cutting oil, low rpm, light to moderate pressure, and periodically stop to clear the chips. I used the 1-3/8" to drill two holes through 1/2" thick (double 1/4" plates) cold rolled steel (1010 or 1020) and was able to do it with my 1/2" variable speed handheld drill but had to take my time. So the bit wouldn't grab. I was in a tight area where there wasn't enough room to use a mag mount drill press and I was really surprised how well this cutter maintained its sharpness. Good luck with your project!
Question:	Do these have a lifetime warranty
Answer:	Yes
Question:	can this cut through 1/8" stainless steel
Answer:	I don’t believe so as they are considered consumables.

Question:	What drills are you guys using? Ive been using my 18 volt ryobi on 1/2 inch birch plywood and my drill overheats after a couple holes
Answer:	with most hole saw sets you spin the hole saw onto the arborand use it when its time to remove it you have to sometimes pry it off from the arbor. This can be done two ways. Sketchy Way Keep the arbor on the drill and hold the drill between your legs and use a large flat head screwdriver and slide it into the side holes and then you can either wack the screwdriver with a hammer or another tool be sure you are wacking it the right direction. you could also help it with some lubricant(wd40) Proper Way Use a pair of adjustable pliers, locking pliers or a vise and hold the arbor at the base. Then use a flat head screwdriver or another pair of adjustable pliers to spin the hole saw off the arbor.
Question:	Does this include a pilot drill bit
Answer:	If you count only what comes in the kit, no you cannot use it without the drill bit, the rotating saw is locked with a nut to the drill bit. However, if you were creative, you could make or get something so that it went through the middle, but still let you lock it to the rotating saw. I suppose you could even take the bit and cut it down to nothing, just leaving the locking area.
Question:	What sizes
Answer:	what do you mean ?don't understand the queston
Question:	Does this come with a case description says yes answered question says no & does the larger arbor have the pins to keep the saw from becoming to tight
Answer:	The LENOX T3 has a 0.070 kerf width of cut.
Question:	Can anyone tell me where to find instructions??? I've used one blade and can't figure out how to remove the auger
Answer:	This set is not for 6 inch holes. Set is awesome for the price
Question:	can this be used without the drill bit
Answer:	Use a diamond coated hole saw for traditional stucco, which is much like stone. I squirt water from a spray bottle onto the cutting surface for lubrication and to reduce airborne dust. Use a hammer drill if possible because stucco is tough.

User questions & answers

Question:	will this set work on hard wood or just soft wood
Answer:	Yes, it will cut through metal
Question:	Is everything that is needed included besides the drill or is there anything i have to buy extra
Answer:	There was a card that came with and it said drills through mild steel. My husband personally would not use it on stainless steel for fear it would dull the teeth on the blades. I really don't know what they mean by mild steel. You might want to research what they consider mild steel. Sorry I couldn't have been more helpful.
Question:	Will this work for everyone
Answer:	Saws: 7/8", 1-1/8", 1-3/8", 1-3/4", 2", 2-1/2"
Question:	What mandrel works with this hole saw
Answer:	The short answer is, No. Hex shanks are for 1/2" impact driver. I don't own a half inch impact driver. These hexshanks work fine in a normal 1/2" drill chock. This question is for a 26pc hole saw set. My set is called the 17 piece contractor's set, and has the larger 1/2" hexshank holesaw cup jigs. Can't totally be trusted here. Good luick!
