a good diamond drill bit

a good diamond drill bit (1/4") is needed quick for parcelain tiles,
my old one from www.diamond-drill-bit-and-tool.com shot after not to many holes (rpm may have been too high).

any one can recommend a good source to order?

Thumbs up Tile / Porcelain Drill Bits

Hello,

Just a quick response to confirm that there is now porcelain drill bits available on the market. These bits are good for ceramic, marble and glass as well, but are strong enough to drill the toughest tile!

Thanks for the info Joe (I'm assuming that's you behind the CC post). Re. the 3/4" and larger core bits - are these for both wet and dry use?

anyone used this bit before? I was dispointed by 1/4" the diamond core drill bit I got before, it did not last long to justify $20+ a piece.

I checked the link, the prices are stiff but I'd buy if they worth it.
how many holes will a bit last? how fast can they drill through hardest 3/8" thick parcelain tiles? I have too many to drill.

Ive never seen a 20.00 drill bit that was worth buying as far as drilling floor tile.
75.00 on the low end for a small bit is a more realistic price for a quality bit that will last through many jobs.
Good Core bits will drill through concrete, stone etc and last many years.A good core bit set of 1" 1 1/4" 1 1/2" 2" 3" 4" is a hefty investment well over 1 thousand dollars.Add the 1/2" increments and the 5 and 6" and you are into several thousand dollars.

$55 does sound a little steep for a 1/4" carbide bit......I could see it if they were diamond. What makes these carbides so special? They don't look that much different than the $6 ones at HD........

I cant believe the price of the felker TM 75 $310 that works out at about £160. We can only get Rubi cutters here and their samilar saw is the diamant dt-250 at £870. Contruction complete havent put any shipping on, that cant be right.

Porcelain drill bits

I want to confirm that we have had great feedback from our customers on these drill bits. We have been told by the manufacturer that they are the only type of its' kind on the market. A small indent must be made in the tile to keep the bit centered, but once they get going they last pretty long. A cooling agent (water , oil) is a good idea to extend the bit life.

Please feel free to call us on Monday to dicuss further if you would like. Thanks! 800-889-0661

After cutting numerous holes for faucets, I would be very interested in low end core drilling setup. This would work wonders for drilling precision holes in stone, porcelain, etc.

Any ideas?

Jason

Core drill bits

Hello,

Basically there are 2 options for your application. For the drilling of basic core holes through ceramic and marble can can buy the bits below individually:

http://www.constructioncomplete.com/...ramicTile.html

But for granite and procelain (the hard stones) you would need to buy a kit like the one below:

Please let me know if we can help further. Thanks!

Rick

tried the Pro Line bits

Spent about $50 for a 1/4" Pro Line bit, this bit is make in England, It looks very high tech.
If you need the feedback about how it worked on the porcelain tiles I have, PM me.

I bought a diamond core bit from these guys:

http://www.ukam.com/electroplated_core_drills.html

I found the site from a post on this forum a while back. My experience is with the 1" bit. It worked fine, drilled appr. 15 holes through porcelain tile. Plenty of life left in the bit. cost was about $50.

The manufacturers of the PTC bits were kind enough to send me a couple to try out. They are fabulous, and I'll post a picture or two in a minute. I might be the guy who sicked them on Construction Complete. I wouldn't have done it, Rick and Joe, if I didn't think they are great products.

We built a dam around the intended hole with plumber's putty. We chucked the bit into a humongous Milwaukee drill motor and let the weight of the tool do most of the work. Might have pushed down just a little, but not much. You don't want to force the bit, or you'll ruin it.
