Rated 4 out of 5 by from Does the job On my second one of these. First one burnt out after 5 hole. I wasn't sure if this was my fault as drilling too fast. Took the plunge to buy another and treated it a little better. 3 hole on still appears ok but time will tell. They are expensive so a bit disappointing when they burn out! My advice is buy one just treat it well.

Rated 5 out of 5 by from Perfect. Just the job. Was apprehensive about the price of this drill bit and it nearly put me off until I added up the cost of all the other cheap bits I have burnt out so decided I had nothing to lose. Overall after my first use of drilling 4 holes into some really hard porcelain tiles I am very impressed at how quickly and efficiently it cut through them. Cut like a knife through butter and no mess as it does what it says on the packet. DRY cuts at high speed. I wouldn't want to keep drilling at high speed for too long as I imagine it would burn out at some point so just knocked my drill speed down a touch and it worked perfectly.

Rated 5 out of 5 by from Works well, in my limited expe After only making a 2mm deep 'saucer' after 30 mins through a 9mm tile using a tungsten bit, and faced with needing to drill a total of 4 holes, decided that I needed to spend some cash on fancy technology. Bought this (v) expensive one ( 6mm ) and a cheaper 7 mm one of another brand, and used this to do donkey work first hole. Preformed almost effortlessly, with the waggle techinique, after first using the tungsen bit to give me a centre punch start. After 4 holes looked like had lots of life left in it.

Rated 5 out of 5 by from Quality Good quality drill bit that makes little work on hard porcelean tiles, i start with 6mm then open with bosch multi construction bits if need bigger hole. Reduces alot of time but lost my drill bit so cant comment on its longivity. worth it if you get 50 to 100 holes out of it though. macrist are great at making tools for tiles

Answer: 
Good question. As with all suction cup guides this is it's downfall. however one of the best methods for this is to do it freehand. Masking tape over the tile mark up were you need the hole and start at a 45 degree angle create a half moon in the tile before moving to 90 degrees and finishing the hole.

Hi
This is the lubricant.
Good luck and remember, don't apply too much pressure when drilling. This will give the drill longer life.
