Rated 5 out of 5 by from Very diverse drill bit. A very good drill but for use with a wide range of materials, I'd strongly recommend it.

Rated 5 out of 5 by from My favourite drill bits I've tried many types of drillbit with disappointment. These drills are simply brilliant for drilling brick, concrete and especially wall and floor tiles. Last for ages too. Half the price at Screwfix compared with the other major retail outlets.

Rated 5 out of 5 by from Excellent Drill Bit Purchased this as my current set didn't include a 7mm piece. Comparing this to my generic drill bits showed the massive difference in quality. A hole that took 2 minutes to make now only takes 10seconds.

Rated 5 out of 5 by from Bosch 'blue' masonry drill The Bosch 'blue' masonry drills are characterized by having accurately sharpened cutting edges which allows the drill to work without wobble or vibration. The sharp cutting edges and their geometry means that this drill is ideal for making holes in fragile materials such as wall tiles (make sure your power drill is NOT set to 'hammer'!). These multipurpose drills will cut through timber as well as masonry, which is a huge benefit when you are drilling through mixed materials such as masonry that contains timber supports. An example of this would be drilling a deep hole through wall tiles that are on a plaster wall with a wooden stud behind. The Bosch 'blue' range are designed for professional use; so sharp; so accurate; so buy them!

Rated 5 out of 5 by from Good drill bits These are spot on for what I need them for. They do a good job and once they are blunt I bin them and buy some more. I use them generally on drilling tiles in bathrooms and have spent a fortune in the past on fancy tile bits. These do the job fine and I get an ok life span out of them. I just buy 3 at a time when on deal.

Rated 5 out of 5 by from Great drill bit These blue tips are fantastic at drilling everything, I've used them on brick wood metal tiles and concrete. They have a great life on them as well.
