Bosch 1x CYL-3 Concrete Drill Bit (for Concrete, Stone, Masonry, 6 x 60 x 100 mm, d 5,5 mm, Professional Accessory for Rotary Drills and Impact Drivers from Most Brands)

good quality masonry drills, drilled into concrete with ease

Good quality drill bits from Bosch they were ideal for my cordless Bosch drill drilling into old bricks and they went through without a problem

Well worth paying for a very capable set of masonry bits. I definitely recommend them.

If you want a small set of masonry drills for home fixings, you cannot go wrong with these

Did the job.. 10 inch of solid brick.. easy

First thing to get out the way is that I use standard bits for indoors and normal brick only, preferring to use SDS for heavy duty jobs - larger holes or harder materials. Although these are listed as concrete I really buy them for longevity rather than actually using them on concrete. Again, I would use an SDS drill and bits for concrete and harder materials like engineering brick. Used on softer materials ( standard block and brick ) these will last a very long time, making them excellent value. I bought this set to replace the last set I bought about ten years ago!! So yes they do last a long time as long as you take reasonable care with them. A very important feature of this set is that it has a 7mm bit. Most sets do not. I don't know about you, but I use 7mm wall plugs for No.10 screws. You can buy 8mm wall plugs instead but it seems a lot easier to just buy a set of bits with a 7mm bit!! It's unfortunate that this set doesn't include a 5.5mm. Oddly that size is sometimes useful for 5mm wall plugs. Don't ask me why but that slight over-size is helpful with some materials, especially plaster. To complement the set, I also buy 3mm drills of the same type. You may wonder why(!) but I find the 3mm drills as an excellent starter when I really need to position the hole accurately. Anyway! They are great drills, buy some!

In general they are a decent set of drill bits. I used this to attach a bracket for an outdoor washing line. The drill bits made short work of mortar between the bricks but took a little time with the brick itself. After a four hole drilling session the bits seem to have stood up as well as can be expected and still had a decently sharp and shaped tip. I did try a set of cheaper ones and they blunted within a minute, so even though these cost a little more, the performance is worth the extra costs.

These are excellent quality drills, replaced a cheaper drill bit that literally melted when drilling into hard bricks, these simply did the job no messing (as they should)

Fa il suo dovere. Data la lunghezza della punta occorre più attenzione nell'eseguire i fori (ma questo non è colpa della punta ovviamente). Dovendo forare il soffitto attraverso 7 cm di legno la presenza di una guida mi ha sicuramente facilitato il compito.

Dovevo perforare delle piastrelle in klinker nel bagno, notoriamente molto resistenti ma allo stesso tempo facilmente scheggiabili. Ne ho provate altre (poi restituite) che si sono spezzate nel foro provocando un notevole danno (poi risolto grazie ai ricordi dei consigli di mio padre grande hobbista). Con queste punte non ho avuto problemi, foratura semplice e fori precisi senza sbavature. Sono solide e non si sono assolutamente usurate nonostante numerosi fori fatti; le consiglio anche per un uso intenso.

It really works well on extremely hard concrete wall

Great price fast delivery thanks
