The diamond particule coating on DRILAX hole saws give superior performance and lifetime. Please note our tools do not need center pilot holes. Center pilot hole drills are mostly for wood, metal, etc.

Drilax tools can drill 1 in depth.

Electroplated diamond coating will wear off if the tool gets too hot. Never let your drill bit run dry. Here is how you could use water to keep the tool cool:
a- You can build a mini water dam around the hole with plumbers putty.
b- You can choose to spray water on the drill bit.
c- Or you can use running water to cool the drill bit.
EASY TO USE
Center pilot drill bits are for wood, metal, etc.; 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. All you need is to keep the drill bit in place until it makes the initial marks.
b- You can start drilling at an angle, with the edge of the drill bit making a C slot and then getting the drill bit up to vertical.
c- You can manually guide the drill bit with wet sponge.

Please use protective gear.

You Get What You Pay For

First off, for the price, the bits were a good value. I got multiple sizes of diamond bit for less than $40 and they did work great for the first 2 holes in 3cm granite. 2 holes each were their max though, and that was with constantly drilling in water at a slow rate for around 30-45 seconds, vacuuming the hole (water and particles both), then rewatering and repeating until all the way through.

The 2" hole bit held up better than the 1/4" bit in granite, but neither will be usable for a third hole which is a shame because I need to drill four 1/4" holes and not just two. I have since purchased a different brand 1/4" bit and it cut both of the other holes without issue and still has diamond abrasive material on the tip following the two holes. Those other bits were more expensive though so like I said in the title, you get what you pay for. Obviously if you are cutting through softer or thinner materials you'll get more holes cut with the bits.

Note: These are not deep enough to cut through 3cm granite without having to cut from both the top and the bottom and ensuring that you keep the holes lined up. I had to cut from the top with the 2" hole saw, then realign and cut from the bottom to get all the way through. I knew that going in and am not downgrading the product based on that, just wanted to make sure everyone that reads the reviews understands that.

Use a template if possible, keep 'em wet, take your time.
by B. Rhodes (5 out of 5 stars)

I was pleasantly surprised how durable they are! They look delicate, as in the diamond coat looks thin, not chippy like concrete core bits might. However, I cut 4 holes with the same bit through thick porcelin tile and 1/2 inch backer board without a hitch, and no sign of wear on the bit. Made a template from a piece of 1x6 pre-drilled through with wood bit, clamped it to tub deck, used regular household spray bottle to keep the hole wet and bit cool throughout each hole drilling, steady but light to moderate pressure on drill, cruised right through each hole. Dont get greedy on the downward pressure or stingy on the water. Again, no noticeable wear on the bit after 4 holes. Although I did not experience any slipping, the completely round shanks might be improved by having facets on them, but no problems this time around.

Nice bit set. Suggest getting the drill guide with it.
by Dakota Dude (4 out of 5 stars)

This is a nice diamond coated drill bit set with sizes ranging from 1/4 to 2" I got them to get some holes in ceramic tile for water pipes to pass thru. We also purchased the Drilax™ Drill Bit Hole Saw Guide Jig Fixture at the same time which made it very easy to get these holes accurately placed. I couldn't find any decent videos on line about how one would get a hole started with this type of bit without the guide as these bits do not have a pilot bit like you would find in a typical wood hole saw. Some better instructions with the bits or the guide and reference to finding "how to" videos would have helped, but we got the job done and the bits and guide performed well.

Way better than other inexpensive sets
by Russell M. (5 out of 5 stars)

I bought another rather inexpensive set recently, and the "diamonds" washed off immediately drilling the first hole through soft sandstone. These are much sturdier. I drilled a total of about 10" through sandstone using the first bit (1.75") and the bit held up very well. Obviously these aren't what a full-time granite driller should buy, but for the homeowner who has occasional reasons to cut holes in stone, these are perfect.

Great Value but didn't quite drill all the way through my 1" Quartz
by Jack (4 out of 5 stars)
May 27, 2019

Used the 2" & 1 3/4 today to drill through 1" Quartz. I used an old powerful Milwaukee drill which is older than me to start the holes. I have it fitted with a drill bit alignment tools u can see in pic. I put plumbers putty on base to stop scratch's and as a water dam. It can be hard to get a precise point to drill but in my case it doesn't matter. I just braced the drill in the corner. It can slip for a second or two but it bites in well then you are fine. Keep flushing with water and drops of dish soap or the bit can bind and twist the drill. The bits went through very well but have not used them twice.

My quartz is 1" thick and bit measured as cutting 1 1/8" but it bottomed out before I broke through. So I tapped the hole with a small ball peak hammer and it broke out. It will take an odd shape out of the bottom of your countertop so beware if it's exposed. In my case nobody will see it.

All in all for the price of one bit at Home Depot I got a set of 6. I'm happy!

Good quality

Took some practice to cut holes in wine bottles for lights, but once I had it down I was popping these things out right and left! Only drawback is that the glass can get stuck IN the bit... and I can't remember if there's a back poke hole to pop the stuck ones out...

Very nice set for the money

Very nice set for the money. Plenty of sizes to choose from and the carrying case is very nice. I used one of the smaller drill bits to drill a hole in an old Mason jar to make a lamp. The Mason jar happened to be the liner of the inside of an older water cooler bottle. I was happy with the ease and speed that the drill cut the glass.

Did the job just fine
by Dina Ashley (5 out of 5 stars)
December 13, 2018

Had to enlarge 3 pre-drilled holes on a granite bathroom vanity from 1 1/8 inch to 1 1/2 inch to accomodate new faucet. Drilled a 1 1/2 inch hole in a 1x4 piece of pine to use as a guide and clamped it over the existing hole. Once the cut is started I removed the guide and sprayed with water as I drilled. Cut pretty well, but don't push too hard or it heats up the drill motor. Took about 15 minutes to cut 3 holes. Some wear on the bit now, but would probably cut a few more holes. Well worth $40.

Worked very well on granite for me.

Wanted to drill a hole in granite for a vessel sink. These worked well, although the granite was a little deeper that the saw depth. Was able to take part out and then finish. After I finish building the vanity, I'll use a different size for the faucet. Very pleased.

great bits

Really happy with these bits. Used one to cut through some pretty hard tile with no problem.Bought the Drilax adjustable guide which works pretty well but had to clamp it to the tile as the suction cup did not hold.
