Important to follow instruction diagram to start bit at an angle to create a crescent shaped cut on the polished surface to guide the bit before tilting it up to vertical or else it may wander. Also good to have a water bottle handy to wet the bit and the cut as you proceed. This serves to keep the bit cool and to stop flyaway dust. I highly recommend this product and I would buy it again.
Be patient and don't rush for best results because too much heat and pressure will wear it down faster than it should. For best results, here are some other tips (applicable to all types of hole saw bits):
1. Start at an angle to create a curved line before going vertical, otherwise your bit will move around
2. Use water to lubricate the surface and drill. Reset/pump the drill every 15-30 seconds to rinse and get some fresh water under the bit
3. Don't push down too hard. Gentle pressure is fine. I have not noticed extra pushing speeding anything up much, but it will eat through your bit much faster. Also ease off the pressure towards the back end to avoid splintering or shattering
4. Some materials take a lot of time, so just be patient. It can take several minutes to cut through some denser materials even if they are less than 1/2 inch
Hole saw worked great!
We needed a 1.5" hole to install our Aquor hose hydrant. We have 4" thick limestone slab skirting around our foundation, with terracotta structural block behind it in this particular section. The previous hole for a frost proof spigot was 1". Knowing that 100yr old terracotta block and limestone can be sensitive we needed to minimize blowout, so went with a brand name vs one of the random ones listed here. The price was cheaper than a coring bit, so figured why not.
(* If you need to install an Aquor* The sizing is accurate on this, so that's a positive! It does fit so that you have just enough meat left for pre-drilling holes for screws, if your in the same position as us trying to fit the fat portions of the circle faced Aquor into Masonry. Hopefully you have a newer construction home that's just a brick veneer with regular concrete and plywood framing. )
[Considering a bulk of the stone was already removed, it seemed reasonable this should work effortlessly.]
Despite water and keeping the diamond teeth clean by continually removing build up, pausing to allow it to cool down... it struggled. This with a Bosch Brute Drill and a Dewalt 20v XR. It started great, the diamonds seemed to loose effectiveness quickly, while in the limestone. Once it hit terracotta it was done. So longevity for us was short lived. Value for money in our particular situation, I would say no.
One thing to note, it kept getting unscrewed from the arbor, this seemed odd as to remove it from the quick connect base it came with, I had to use a vise and small pipe wrench. (Both in such a mannerism to prevent tweaking it.) So if using in a place that if it untwist, you could loose it, continually check for tightness if not using the quick connect fitting.
[ I ordered a 12" Bosch arbor with the SDS+ end to use with our Bulldog, however the threading spacing was different, correct size just a different thread pattern.
***We used a Master Force #3 arbor with their extender so this could have been part of the problem***. It didn't fit the Spyder or Dewalt Arbors we already had.]
I ended up switching to a 1.25" Lennox diamond saw to finish, It went through effortlessly, with the same arbor and extender.
(I should have just bought one specifically for coring, lesson learned. If you have reinforced bomb proof/ bridge grade concrete basement walls... 100% just get a coring hole saw. We have two others to install that go through limestone and extra strong concrete with #11 & #14 rebar... we won't be using this hole saw. 😂)
If you're using this for thin material you should be fine. I do not recommend using this on porcelain tiles though! Get a continuous diamond coated edge vs teeth.

My aim was to run this 4” diamond tipped hole saw bit on a grinder, as I do with a 2” bit. The 2” holes are for venting and the 4” for light plates and the material is 1” thick Hardie. 1” or thinner.
I’d already learned the hard way that the 2” bits mandrel thread wasn’t compatible with that of my grinder, and remedied that with an adaptor from Milwaukee (link at bottom), but would it work with the 4” as well?
Much to my delight I found that the 4” shares the same thread pattern as the 2” once you’ve removed the mandrel housing adaptor (I don’t know what the part is actually named so that’s what I’m calling it) that comes screwed into the hole saw. Understandably, these hole saws are meant to be run on mandrels in drills turning at appropriate speeds, not on the business end of a grinder spinning at slightly faster speeds, and so this 4” is shipped with an adapter screwed into it so it’s compatible with the mandrel. But again, to my delight, that adapter spins right out, and then hole saw spins onto the Milwaukee Grinder Adapter which is spun onto the grinder. So long as everything keeps turning to the right, it should stay that way.
Though I do offer a warning (it can get a little western cutting 4” holes through 1” Hardie at questionable rpms) I also leave a strong recommendation for this set up. Until they come up with a better way, this is pretty good. The bit lasts longer than any other. It’s super fast. The plugs either fly right out at dangerous speeds or, at most I have to tap the bit a couple of times to shake it out. And it’s easy on the grinder as the bits doing all of the work.
So I really hope someone gets something from this, should they have the patience and time to sift through the 438 reviews.
