Bosch 7x EXPERT CYL-9 MultiConstruction Drill Bit Set (for Concrete, Soft tiles, Ø 5-10 mm, Professional Accessory Impact Drill/Driver, Rotary Drill/Drivers)

I have been using these drills for many year, cut through metal wood, ceramic, brick. Great drills at a good price

Always good drill bits and no need for hammer action, which is especially handy for brittle, hard surfaces like tiles for example.

Purchased over a year ago, best bits I have had, drilled brick, concrete and 12mm steel girder (use lubricant).Watching the 1 star review video, the blokes chuck is wobbling like a good un, nothing to do with bitsLess than 3 quid a drill, excellent value. Gonna buy some for son-in-law. (save him borrowing mine)

These drill bits are very good and would recommend them for general DIY around the house but 1x of the drill bits burnt out the first time I used it and I was only drilling into regular kiln dried house brick (not particularly hard material).

Good selection of sizes, still going strong, well made

I tend to only use Bosch drill bits now anyway but from past results and experiences, I find that they do exactly as designed which is drill through the material they're made to in a straight line with no issues.I have found that despite them being widely used, some will last longer than others, although the material obviously has an impact on this.Comes in a tough box, easy to get into and use. Can't say much more but they rarely if ever disappoint.

Worked great on Ceramic tiles, didn't slip when starting and went through with ease. Set drill to low speed and let the bit do the work.One hole had wooden stud behind and it struggled a little but still did the job. But wouldn't recommend for wood (use a wood bit)Flies through masonry as well. Would definitely recommend.

Was looking for something to be able to stand up to most hard surfaces, these drill anything in a new build or old houses, great centring point as well, if your looking for one of the best long lasting bits buy these
