Professional Masonry Drill Bit Set (10PCS) for Glass/Brick/Plastic/Cement/Wood/Tile/Etc, Industrial Strength Carbide Drill Bit Tip, 1/8"-1/2" by TITGGI

Works great. Cuts through engineered sill stone like butter. The smallest bit was a little bigger than I needed for my plastic anchors so I had to grind down the flares on the sides of the bit tip a little to make the holes in the stone a little smaller and the metal on the tip was super-hard. Comparable to bits costing 3/4x as much.

This drill bit set is high quality and works great on all kinds of materials like tile, wood, and concrete. Great value for the price, and I’m very happy with the performance. Highly recommend for both DIY and professional use!

They Are nice but some of them broke quickly that’s why I took one star away however the ones that work are some of my favorite drill bits that I’ve had. They rip right through any thing that I’ve put them against even when the ones that broke it wasn’t the material I drilled through as I used another bit in the box and it ripped through with no problem I honestly believe any bit is subject to breaking at any moment depending upon circumstance’s.

Why did you pick this product vs others?:These are nicely designed well made bits that do the job and last. I would buy again.

Worked well. A great product at a good price.

Just WOW - I was able to drill into tiles and cinder blocks without any issues. Can now mount shelves in my garage. Easy to use with my drill and makes perfect holes.

Needed something quick to install a new doorbell. The drill bits I had just weren't doing the trick on my stucco exterior wall. Bought these and at first didn't penetrate as easily as I thought they would, but they did brake through eventually. The tip wore out a bit after only 5 minutes of use. Got me thinking that maybe after prolonged use they would eventually dull out and be useless. Im not surprised considering the price I got them at. All in all it did the job, but would not recommend for active use in construction or a professional that uses bits as a daily thing.I want to give it 4 stars but the tip of the bit dulling out as fast as it did was disappointing.

I bought these to do a couple of projects on a brick house. Admittedly the brick on this house is a hard as any I have ever seen. The house is more than 50 years old. Using the smaller 1/8 to drill two pilot holes for a hose rack I went through the first bit in one hole of about two inches depth. It just wore out. I use the next size up for the second one. From the looks of it, it will not drill more than three. The larger bits work fine if you control speed and heat. Just don’t expect the to last long enough to go into the tool drawer.
