Good job 👍 I'd use a variable speed grinder low rpm with a 35mm vacuum braised holesaw in M14 fitment. Enter the surface with the bit tipped at a slight angle, will prevent any accidental damage if the bit decides to walk. Dust extraction is ideal or use putty to build a well around area and use water. I'm a stone mason to trade and experienced granite fabricator if it means anything.
get a makita angle grinder and a 1 3/8 bit. use masking tape and tape 3 layers from the edge of the stone to the backsplash...measure 2 1/2 inches from edge and mark it. use 1 3/8 but circle your mark. put bit on drill and drill away. safest way to do it.
Any chance you can drill another hole in your granite countertop and show it from a different angle? I don't have granite countertops, but I'm just curious.
Not recommended. You don't layout your location, don't protect your counter top, show how to start the hole, and while you are drilling you are pivoting the core bit. Yikes, how not to do it. "just softly tapping it." Oy.
You didn't show how to start drilling the hole which is the MOST CRITICAL PART of core drilling. Anyone reading this, know that without a guide or lots of experience, your bit WILL SLIP
you also didn't mention what the clearance was underneath the countertop . . . ( for the fixture/dispenser, sink edge, or any other possible interference issues to be aware of ) . . . before you started drilling.
@@robozstarrr8930 your absolutely right !! Didn't mark and failed to go in at a slight angle i can almost bet that grinder spinned across the counter top a couple time s
I need to drill a 35mm hole in a schock kitchen sink for an air gap. the material is 80% quartz. Should I use a diamond hole saw? And should i drill from underneath the sink? Thanks.
about how long was this process? obviously youve edited it to take out too much time with just the drill on but I'm just curious how long the entire process was? I think I understand that I'm suppoised to go really slow to avoid cracking it.
@@SiYanara 👈What he means is, put the bit into the freezer with water to form ice. The ice frozen inside the bit will help keep the bit cool during part of the drilling time.
Unfortunately RO water still has positive ORP and is stripped of all minerals. While it may be clean its dead water. Check out Kangen water its living water. You will need to add a remineralzation added to achieve negative ion charge but can be achieved.
I wonder if you just vacuumed the dust out and used Vaseline on the inside of the bit if it would go smoother. Just thinking the blade has to keep pushing the wet dust in the crack. Good vid. I have to cut hole for disposal button.
@@MuckoMan you wouldn't want Vaseline as it would grab the dust and keep it in the hole. What you want to do is get a hose or a good spray bottle and continually spray while drilling to wash of excess residue not only to cool the bit but to lubricate. Clearing the groves is the most important step in drilling the build up can cause excess drag and heat leading to cracks or chips around the hole or worst through the entire work piece.
Seems like one of those things to pay for in life. Option A) Spend at least $30 you likely only need once and burden the risk of thousands of damage if it goes wrong Option B) Pay $50-100 and have it done right AND the have contractors' insurance as a backup.
Yes, it's really better to surround the hole with towels (sopping wet rag) or putty and have the drill operate in a puddle of water. Or pour some water on the hole *often* and let the drill bit cool down.
You paid about 40 bucks for tools to drink the hole when you could have paid the extra money to have it done professionally so you dont mess things up.
If you grab some plumbers putty you can build a small wall around the hole with water in it to keep the blade cool and keep dust down.

Hi, what type of material is your kitchen slab
Thanks! I used the same hole saw & bit & it worked great!
Nice man. That takes guts for a home owner. Heard allot of horror stories from people trying this themselves.
What are some of these stories?
That’s scary as hell drilling through such nice countertops
Nice. What drill bit did you end us using? Milwaukee drill bit?
Any chance you can drill another hole in your granite countertop and show it from a different angle? I don't have granite countertops, but I'm just curious.
Carlos Figueroa that's good man. You had me rollin
Too funny :)
How do you know you are not drilling into edge of the stainless steel sink ?
Surely he measured lol. I would hope.

hi Can you send me the link to that DRILL bit ? where did you buy it from? any link to buy? LOWES?
Or Home Depot
Very helpful, thank you!
exact video i wanted to see, thank you very much good sir but i didnt catch what kind of bit that was

Simon M how do you stop the slipping?
@@robozstarrr8930 your absolutely right !! Didn't mark and failed to go in at a slight angle i can almost bet that grinder spinned across the counter top a couple time s
@@JenniferShipp1 you stop the slip by starting at a slight angle. Not!! Flush with the counter top
@Simon M - So, what's the best way to start? So the bit won't slip?

Robert Stiles don’t drill underneath. Only top. Use water so bit won’t get hot. And get a bit that just a little bigger

ice cubes in the bit helps.

@@farmalmta makes sense.
What's the milky material you put on the granite part way through the vid? Thx.
It's the dust from the granite.... he didn't put anything!
Water mixing with the granite dust
$50 to $100.. they are insured. They break it, they replace it. You break it.. ouch.

It's amazing what a great job you did. What kind of drilldo did you use?
Like in other aspects of life, he had to use a drilldo to get the job done 😂
Great video buddy. Did you have to lube the hole?
Can you use the same type of circular drill bit for a 1/4" hole too?
yes.
You should start drilling from an angle so it starts the groove without moving around all over the place.
Yeah but with a diamond tip drill so you can cut it in a minute and go to lunch. Time is money.
Didn't know that.it been always a problem
Thank you!
very nice, i love that drill, i have the same one!
Also, do they only come in one color?
Can you also use a different drill? I don't like Dewalt.
why?
Does anyone have any tips on how to get the hole started? Please.
Buy her two drinks and say *"Do you come here often?"*
Dos semanas despues quedo listo
what was the total time drilling?
Took about 5-8 min total drilling time

you did it!!
just lose the air gap use that hole

I wish It would be $50-$100. The two quotes I have got were $180+tax and $250.
Can't be scared of everything ... no end to it
@@truthalonetriumphs6572 Ok?
Good plan but you need to hold the drill straight and don’t oscillate that will cause elongated holes
Wrong!! You use copper chisels and pounding stones.
We prefer cut the stone from the back side carefully and resin for finishing. It`s faster and neat enough.
watching you work is worse than getting teeth pulled!
They make better bits so….
get to the drilling
STOP how to video ! NOT NEAR ENOUGH WATER BIT NOT OVER HEAT

mike Lowry Im about to do the same thing where is my drill
takes me 11 seconds to drill that same hole...put your drill away and call a pro
Exactly. I would just pay the extra money and pay a professional
Because it's a race. If it's not as fast as you, it's wrong!
Then he’d have to meet a know it all buffoon like you... for a whole 11 seconds.
And pay you $100 bucks so you could do it at breakneck speed? No thanks.
who would you hire? a plumber? a kitchen fitters?
