How strong a drill do you need for these bits to work, a standard home drill with a battery, an industrial strength or an air-drill? To be used on 3/4" granite.

Standard home drill or battery drill will work. I used them on 1/4" granite.

just a 3/8 cheap type, slow and a water dam is the way, it is hard to get started but if you get it started on one edge it will then start. holding it to start takes a steady hand to get it started, but then it great it is great'

A Standard drill with a battery was able to cut through a 1'' granite countertop with no problem. The bit was still good after.

Any drill will work however a variable speed is better and should use water to keep them from overheating

The drill size or type doesn't matter. Take your time and when you do drill try to make a dam around the hole with plumbers putty. Add a little water and this will help keep the bit cool and not wear out too fast.

The size or strength of the drill is not the problem. These bits were designed for light duty work not exceeding 3/8" inch, (i.e., ceramic tile, glass, etc.) You would wear the bit out before you went thru 3/4" granite. Commercial granite installers use heavy duty commercial diamond or carbide bits with a pilot for drilling holes in granite. And, most of this is done in a shop on a drill press. If you still want to give it a try use a heavy duty 3/8" or 1/2" drill. Good Luck

Yes , I use a sds 24 and a 12 inch 3/8 masonary bit occasionally in my line of work. I wouldn't use it as sds drill all the time, it's not made for that.

When using the appropriate drill bits,I have found this drill to be good for all materials. Works well with masonry bits,but will never out-perform a hammer drill for this application.

This is a heavy duty 3/8 drill that is not hampered by battery power. With a 14 inch shank you have more chance of bending your bit than slowing down this drill. It can easily do it but its variable and slower than fast is recommended.

i just got mine about a week ago, but i have used a 3/8 diamond quarter round bit to edge some stone i am working on. the power will work, but you are cutting stone and need to go slow and have all the water you can stand flowing. this would not work on a full bullnose bit, on stone anyway!mike

The drill itself can be used to drive something that will cut the granite, but I do not know if the concrete core bit can be successfully used to cut the stone. I bet the manufacturer of the bit can answer that question.

yes would need right bit for granite. Drill would be fine. Might wobble the granite a little if the pressure wavers or changes in any way. Tim

You can use a regular drill. Just make sure it is tight around shank. For best results use dremel. Anything is possible

Buy the Dremel 9929 bit. It's almost the cost of this whole set, but will engrave granite stone, and will last longer than the cheap coated bits.

if i was going to try i would get a separate set of just drill bits, anything steel alloy seems to get good ratings, and i would drill a hole before running these through something that thick, one inch would be about the max, since the bits are only a few inches long and the threading teeth start about a half inch in. Just keep in mind any expensive small drill bits will still break if you don't take your time working with metal.

I purchased a 1.375" diamond hole cutter bit that requires water when drilling each of the three holes required into a granite top. Not as difficult as it sounds, you just need a make a dam and have some water standing by. When the hole gets dry, stop and add some water. Good Luck, Greg MacCarthy

It is a 1/2" chuck, so it's a little heavier than a 3/8" drill. The carbide inserts in the chuck really help hold the bits much better than the DeWalts, I think the measured comparison is about twice the gripping force.

Though I have NOT tried granite I would say at worst you may need the carbide tip which I believe is available. The one that came with my kit has worked so far on a lot of tools/metals and still seems good to go.

Actually, I have not installed this yet, but it will be installed in a 1" thick wood countertop.If your concern is drilling a hole through 1" granite, my advise is to find a professionalwho can do it for you. I don't know if a diamond tipped drill bit in an average electric drill would do it. For starters, the drill bit will tend to skate all over the surface.If you do manage to get the hole started in the right spot, it would be a long, tedious process & without extreme care you might chip the granite.

These are regular shank drill bits, SDS bits just pushes in to a chuck without tightening and longer. So if your drill chuck doesn't tighten with a key or by hand then these won't work. They usually are a harden steel for chipping or use in a hammer drill and I believe come in larger sizes. This drill set seems to be a very good set for up to 1/4'" material as far as my use so far, and is nicely packaged for your tool box.

These bits are for concrete drilling. You will need a drill that will be able to take a 1/2" shank for larger bits . If you're drilling many holes go with heavy duty electric hammer drill. If you're a homeowner go with heavy duty hammer drill 18 volt or above. Hammer drills take a beating don't waste your money on cheaper models. Go with any heavy duty model bosch hammer drill either electric or 18 volt cordless and you will be able to use these bits.

Yes, it's designed for 3/4" holes. In a 3/4" hole it's a little loose so if you have a drill bit just a tiny bit smaller (probably metric), try that. It's much more stable. BTW, the things work beautifully if the piece you're holding has flat edges. If they're rounded at all, the work piece will jump all over the place.
