The drills is of a extreme good quality, goes through ceramic tiles and concrete like butter without using hammer function. ;)

These are great; I'm using them in an 18v cordless hammer and 18v drill drivers, and they go through anything I've come across quickly and easily. They're particularly good where you've a timber batten going into brick or breeze block, as you can usually do both holes with the one bit. They can even put a reasonably clean hole into wood and MDF. As to whether I'm getting more holes per charge, I don't know. The bits themselves do seem to be lasting well though.The only downside to this set is the case, it's really hopeless. It's difficult to get the clear cover back on, and the smaller bits always fall out of the slots in the holder, or you end up tipping the whole lot out to get one of the smaller bits. Apart from that, the bits themselves are great.

Le gros avantage de ces forêts est qu'ils sont utilisables dans une grande variété de matériaux, comme parpaing, brique, bois, plâtre... Ils sont conçus pour travailler sans percussion tout en réduisant la fatigue du matériel, notamment grâce à la pointe carbure. Ils s'utilisent à faible vitesse donc vraiment adaptés pour une visseuse sans fil. Pour un bricoleur occasionnel, c'est vraiment bien. Votre visseuse suffit, même pour du béton, et quand bien même vous n'avez pas le rendement d'une machine percussion avec mêche béton, pour quelques trous par an, c'est acceptable. Cela vous dispense d'investir dans une perceuse à percussion et deux coffrets de mêches (bois et matériaux). Seulement 3 étoiles car il vaut mieux préférer le coffret 5 mêches (IRW10501938): le diamètre 12 ne passe pas dans la plupart des machines et le 7 n'est pas courant... En plus il est bien moins cher...

Really good drill bit set bought as an additional set to those I already owned. The quality didn't look quite as good as those I already owned as the case was slightly damaged on arrival hence the loss of one star. The set also lacjed s 5.5 mm bit which i use quite often. Time will tell if they are as good as my originals.

I needed to drill through a thick porcelain bathroom tile, and my existing masonry bit just wasn't up to the job. After watching some YouTube videos, I saw that these drill bits got great reviews for just that job, and so I went ahead a got them. It turned out to be an excellent choice – these drill bits are excellent.
