Diamond drill bits????

[mingualez]

Got some bits to cut porcelain tiles approx 8mm. Now I know you'll probably call me a mug LOL. But for logistic reasons I got some B+Q pro bits. First tile I cut went through ok second cut was a nightmare. I dropped the drill down to medium torque but the bit and tile got very hot and the bit was glowing hot, I kept cooling down the tile with water and giving the bit a break to cool. I take it this is because the bit is poor quality??? should I take it back or am i doing something wrong??
Thanks in advance..

Try holding a wet sponge against the bit whilst drilling , to stop it over heating...

When drilling holes through Porcelain you should always use water cooling as you drill and not wait until the bits glowing, as the friction builds up very quickly and will over heat and damage the drill bit in no time at all.

Have a look at 365 Drills, one of the community forum sponsers for a propper drilling kit

If you decide to take them back to B&Q don't say your trade, They won't give you your money back

Porsadrill is our brand of drills made from ultra hard JR4 diamonds and use very thin metal to reduce heat. Above is our 8mm pack of four at £29.99

Thats how we could drill 150 holes in one weekend (see full project)

And probably why after sales of these on ebay we have a feedback rating of 1115 positive feedbacks from customers we supply globally. Feedback Proof

We are a British Company exporting these kits all over the world and have a solid reputation for diamond drilling commercial grade C5 porcelain tiles.

All our kits are time proven with professional installers and are excellent value for money.

Thanks for the advice peeps. 365 that kit is good value, may well have to purchase one of those.

How do you control the speed?

A friend of mine uses the B&Q Drills, and has never had a problem with them. It sounds to me like you aren't using enough water. You should try one of these, and keep the speed low.
The 365 Drills have a very good reputation, and should easily outlast the B&Q Drills, from what i hear, but i'd still use the linked guide.

Just so you know where we stand with regards to quality. Our market is professional installerS so we expect repeat sales.

B&Q etc aim at DIY so they do not expect their products to perform as long or to be as durable.

We (I) use the most expensive grade of commercial diamonds which I personally selected when I went to the factory in Shanghai.

Richard Hazell and Nigel Stokes went to the factory to personally select the diamonds that encrust each drill bit. They chose the most durable and of course the most expensive. This is a ten year project and the Porsadrill brand is being built in the same way as Duracell brand their batteries. Stronger, Longer, Harder.


We have a comprehensive set of rules about diamond strength, density and loading. You cant get stronger commercial diamonds than ours because we use the best.

I didnt go half way round the world and put my suit on to tell those people we wanted to cut costs. I told them to give us the strongest, hardest most expensive commercial diamonds they could.

You cant get more durable than that per 1mm.

Drilling C5 grade porcelain tiles is a fight between super hard material and diamond durability. The difference between a DIY drill that runs out of steam at 1 hole is whats put on the end. We make sure its the hard stuff.

And at £29.99 for a pack of FOUR thats superb value for money (plus of course you guys get trade prices - Just ask)

Hard tiles demand even harder diamond drills....

Its not me who does the talking about feedback. We leave that to the forum users who talk honestly. Plus we refer you to our ebay sales.

So far the score is 1155 Postive. COMPLAINTS 0

Ebay customers who choose to leave feeback after purchase. Latest results....

As a consumer you have choice. In 1995 there was no choice and you had to buy expensive drilling rigs costing £300 plus. Today there is more choice than ever. We just believe ours is the best product.

Don't mind me while I bump up some of the old threads. I wont be doing this much more. Just the last few in the Tile Drilling forum - How to Drill Porcelain Tiles. Just one of the many tiling advice forums.
