Thanks for Watching,
Thrifty Tani,
This video just persuaded me that I really don't want a round drop-in sink for my vanity. That vessel style, and the rectangular bar sink, are looking better :)
Wow, this is so brilliant, it's a total makeover. I couldn't cut it, but I will get somebody who can! Thanks.
If using water with a "dry" saw plug it into a GFCI outlet to help prevent
Looks fantastic! Note: I believe you would have saved 3/4 of the time using a diamond-tipped drill bit around 1/2" to cut holes in each corner. thus you'd make the 4 straight cuts into the holes and be done with cutting. Thanks for the video and suggestion to go with engineered!
Thanks! You’re absolutely right, that would have saved a huge amount of cutting. Thanks for the suggestion!
Do this as a trade have for years if you cross cut the corners from both sides and tak chisel and break the triangles loose from the inside of the cut out it should fall right out no need to flip and saves time you can do oval and circle holes with a straight blade aswell
👏🏾nice work, I'm a stonemason and install benchtops daily not gonna lie this was a bit painful to watch but you got it done in the end👍 I don't recommend doing this yourself as it's not as easy as it looks and to easy to wreck a perfectly good piece of stone. Don't drill holes in the corners as once your near the end of your cut the weight will make the offcut drop and take a big chunk of the stone with it
I appreciate your professional opinion! Man, I agree, those corners were tricky, there was definitely a fine line between success and another trip to the countertop store. Thanks for sharing!
@Lts Van Dan, to the contrary, drill holes at the 4 corners. Support the worktop throughout and the piece will not drop at all.
I am planning on doing something similar but dropping two basins side by side. What would a safe minimal distance be to cut the holes? I assume I would also need some sort of support structure underneath…
@Еrica Lasmarias, I was waiting for Van Dam to reply as he will know better.
I don't think that there is any minimum distance other than what is practicable and reasonable, so say a couple of inches. If the corners of the sinks are sitting on the countertop, then this will be their support. If they are undermount, then you'd have to build a frame underneath to support their weight.
Whereabouts are you? Unlikely near me, I suppose.
@Erica, for undermount they use clips and also rely on the silicon adhesion but if I was to do it for myself, I'd support further with a frame underneath. Hence the suggestion in the previous comment.
one of the best instructional videos I have seen on youtube. Thank you!
Thank you Marcin!
why didnt you cut round holes on 4 corners first ??
Should definitely warn people of silica dust, people end up with lung transplants cutting stone.
If you use air tools you don't have to worry about getting shocked.
Very True, thanks for mentioning it.
what you demonstrated is a quartz?
grab a gfci plug adapter for a couple bucks and you wont have to worry as much about the water shocking you.
Where did you get the countertop and how much was it? Thinking of doing this for our bathroom!
Anthony Tausig, where do you live? I got it from a local granite shop.

How did you cut the corner?
I think if You use proper heavy duty gloves would prevent the electric shock.
well done
Nice
Great video, but how do you go about cutting in place? As all the dust in the house is not wanted, but flooding the kitchen is not an option either :)
I currently have an undermount standard double bowl sink and want to install a drop in kohler vault farmhouse sink. So I don't need to polish (cuts not visible), but I need to cut in place.
Thank you!
Looking for this answer. We are changing cooktops and the new one is 1/2 bigger. So, I am needing to cut in place
You can buy blades meant to be used dry. What I recommend doing if you don’t want to do that, because it does cause it to chip easier. Is getting a couple levels or something flat to put on each side of the hole you will cut, once you secure them with a clamp you can put a tub or just some towels in the front at your feet because not much water is needed. Just be sure to shim up the back so it drains to the front when using this method.
How long did it take you to cut this?
Erika T, it took a couple days to triple measure my cuts and figure out my plan. The actual cutting took a couple of hours. But I took my time to make sure I didn't make mistakes.

Certainly not the right way of doing this job, but he wanted to do it and upload a video, so there you go...
What's the right way?
@Jay Gunn,
Never use electric tools with water that aren't designed to work with water. Use a stone cutting saw with water inlet.
Drill 4 holes at the corners. Then connect them with the saw. Support the piece under neath.
Do not trim with the grinder whether forward or dragging it. Use proper diamond polishing disks.
It's not a difficult job. Do it right, do it safely.
@@July-A7 thank you!
@Jay Gunn,

This guy knows how to do it. Though he dry cuts it.
@@July-A7 perfect, i bought the prefab quartz already but i don't wanna pay $1,800 to cut a undermount sink whole, a 45 degree angle corner, and hot top whole. So. Thanks again. I'll do more research before i start but I'm watching the video you sent right now.
My in-laws had the granite in their kitchen replaced in an insurance claim so they gave us their old granite. We were able to cut the pieces to fit our kitchen, including a new hole for the sink based on your videos. We used a circular saw with a diamond tipped turbo blade for 95% of the cuts with a level clamped down as a guide. We also drilled out the corners of the sink with a 1-1/4” hole saw before making the other cuts, which helped a lot. Anyway, thanks for posting, your series of videos was probably the most informative in terms of sanding/cutting.
Awesome job, can’t go wrong with free granite! Using the hole saw in the corners is an excellent idea. I wish I had done that to save me a bunch of time. I appreciate your comment, thanks!
People also over charge! for this!
I need to remove a granite kitchen top, I want to cut a section that is glued to plywood can I use the diamond blade to cut granite and about 1/8" plywood?
Same here thanks for the videos! :D Not going to pay someone when i know i can do it myself! thanks a bunch!
Oscar M , you're welcome!
You should have used the hole saw on the 4 corners
But how did you smooth out the edges. Rough cutting is the easy part.
Hey Rob! Check out my videos on polishing. It’ll show you the tools needed and how to do it.
Gloves are betty important
amazing what a 4.5" angle grinder can do, so many projects can be done
can i use a cordless grinder to avoid electric shocks ??
Hi Paul! I’d absolutely use a battery powered grinder if I had one. I’d imagine the only drawback would be less power and having to recharge the battery intermittently.
Excellent......!
Great quick how to....lesson
Thank you!
What in the shit?
good job!
Mikel Kd Thank you!
Fak this! I’m hiring a pro to do this
thank you , great job, good tips
You’re welcome, I appreciate you taking the time to comment!
how did u make the edges smooth
You can use diamond polishing pads. One of my videos shows how to polish the edge of a countertop slab. It’s the same process.
Leave this work to the professionals PENNY SAVERS!!! Avoid the trouble and buy a top mounted sink and you dont have to deaL with all of this... this guy only showed 10% of the labor and like 20% of the tools needed.. the grinder he's holding is not even variable speed.. theres a lot ge is not showing so is not as simple as it looks. So saving $100 dlls will cost you more than it saves you after you ruin the piece of quartz and end up calling a professional to remake your countertop...
Calm down I do the same thing for a living, don't exaggerate
