These bits are now my go to ones as they went through concrete like a very hot thing through butter.Drilled about 9 billion holes (at least that’s how my arms feel) and still very little sign of wear. In a couple of tight spots I bunged them in my battery combi drill on hammer and they still performed extremely well.

Excellent bits, as a builder I use an SDS nearly every day, and it's worth the little bit extra as they last so much longer and allow easy of use especially when you're trying to drill into something while using one hand up a ladder!

Excellent drill bit. I didn't rush the 20 holes I had to drill at 200mm deep and let the drill do the work Instead of forcing the Issue. I was really pleased with the very little wear evident and definitely see this being able to do many, many more holes.

Having used a number of SDS bits, I have to say these have performed exceptionally well so far.This set covers the majority of the most useful sizes and they have so far stood up well to regular use.

Cut through Brick and Concrete like a hot knife through butter. I was a bit hesitant to spend £18 on Drill bit set but I am glad I did as these made my job so easy. I bought a canopy for my patio doors, from Amazon and I needed a 10mm drill bit to drill 6 × holes in my masonry wall which would have been a struggle without a proper drill machine and bits.I bought Bosch SDS GBH 2 26F and the above drill bit set and I am very impressed by the sheer power and quality of these Expert SDS range bits. Within 10 mins all 6× 10mm holes were done. Also drill bit still looks like new and I believe it will last me a life time. Money well spent.

I’m a Bosch fan and I haven’t any problems with any of their kit - this product is no exception.

Needed to drill a few 10mm holes in brickwork of my house (Hanging a heavy gate) I have an old Bosch hammer drill (Green body) which has served me well for over 30 years. Tried to drill a smaller pilot hole on hammer action and blunted all the drills I had. Bought some new Bosch drills and managed to get a couple of holes before they went blunt. Decided it was time to buy a new hammer drill, and bought the Bosch GBH 2-28 F, which is supplied with two chuck types, both quick change. I first tried the ‘normal’ chuck with the newish used drills I had bought, no luck, still over heating and not doing the job. So next I decided to try the SDS plus chuck. Bought the drills that this review is about and WOW!!!!! I went through the brick like it wasn’t there! I also use it on some smaller holes, same result, like drilling through air! Ok, I don’t drill holes four a living, so someone might say I was doing something wrong with my old drill, but I’m just saying that this combo is amazing!
