Bosch 7x EXPERT CYL-9 MultiConstruction Drill Bit Set (for Concrete, Soft tiles, Ø 4-12 mm, Professional Accessory Impact Drill/Driver, Rotary Drill/Drivers)

Good quality

Present for the other half’s birthday.. he finds an excuse to use them constantly! Very happy.

I've had the older version of these bits for some time now, it looks like just the packaging has changed. I've used them for wood, plastic, brick, breeze block and concrete and they are great at almost everything. They genuinely do start on a point, I've not had any issues with wandering bits and indeed haven't needed to counter punch either. Holes have all been crisp and sharp, using my bosch professional 18v drill.I did try using them on an extremely hard concrete slab where they were a bit slow, I suspect a dedicated concrete bit would have been easier.......and probably should have used a sds drill.I leave these in my drill case as my go to set of bits and I rarely break out anything else.

The 5mm bit was clearly missing from the unopened set. Only free return option is to drive to nearest UPS...

I have a side-gig installing surveillance equipment and alarms and these are my go-to simply because one set of drill bits will drill into wood, metal and best of all, literally any kind of masonry. They are definitely best on masonry, they work very well on metal and probably least best on wood. They’re not in hard plastic and it can melt on them, but I don’t think any drill bits would handle melting plastic!If you’re a DIY’er and you just want a set of drill bits that work. This is that set of drill bits.I would love to know why they have the blue coating. It’s certainly distinctive.

Perfect for getting through tough masonry. You will need a hammer action drill. I have had no problems. Buy quality and you will only need to buy once.

These bits are great for price they do the jobs really well would buy again & recommend 🍺🍺

Set di punte top.....usate per un paio di fori nel granito non hanno dato alcun problema!

sehr gute Qualität für die meisten Arbeiten daheim

Très utile

Gebruik deze boren al weer een tijd. Ik vind ze handig bij m'n schroefboormachine. Een setje om te boren in diverse materialen.

...men hur kan jag de när jag ännu inte använt borrarna? Därför ger jag 3 i betyg. (Borrarna ser bra ut. Tror jag kommer att bli nöjd...)
