I had this item kindly sent by Werkzeugbar (S&R) for an honest review of the product.Summary they are grate quality drill bits for concrete and masonry. Nice storage case to hold them in place and save you losing them. Good variety of sizes.Sizes:5x110mm6x160mm8x160mm10x160mmGood points about the drill bits very good and make easy use of concrete and masonry after using to up in a light in the garden. Good sizes as they come in 5, 6, 8, 10 mm. Made from good quality materials which will make the drill bits last much longer compared to cheaper bit on the market. Its made with a chisel shaped head which is used to create less vibration and clear material quicker and is also coated in a thermal coating which stops the bits bending under heat. They are easily slotted into the drill with slots in the base of the bit to make sure it doesn’t slip in the drill. They are very easy to use and can be used in a large number of drills. I Have another set of drill bits from this company and have lasted 6 months and used many times and have not broken,faded or damaged they are such good quality these are no different such good quality. I would highly recommend getting these to add to the tool box and a must have.Overall I'm very happy with the set and I know will last a long time and will perform when I need them to. Grate price for such a useful set of drill bits. Grate company and good quick delivery with good packaging.

It is the second time I have brought these drills they work really well. However delivery was four days late not as described at the checkout.

Bought these when the ones supplied with the sds drill where reduced to blunt lumps of metal having made a slight indentation in the granite wall.These where nicely packaged and more importantly drilled holes like the granite was plaster!!! Fantastic bits of kit!

Drilling holes and it did a fair job

Does what it says, the granite walls in my house are hard to drill and this product help me greatly.

These were used for masonry wall and what a difference it made. So easy to go through brick. Like the fact they in a case so keeps them all together

Great product & great service.

Excellent piece of kit-cuts through granite with ease.
