Tech Traders ® 3 x 115mm 4.5" Diamond Disc Cutting Blade Angle Grinder Stone Brick Concrete

Tough blades at a great price. Cut through concrete slabs easily, and didn't ware too quickly.

I had a dozen 60x90 cm concrete slabs each 5cm thick so I bought a couple of packs of these discs.I used one of these discs to cut them all in half with about 2mm of wear on the disc.I was impressed both with the speed of cutting and the durability.

Good value

Worked perfectly for cutting slabs for a patio.

These blades are really good ..iv cut a 5 metre trench 8 inches wide through 7 inches of concrete and used 1 blade. I cut the length and then cuts across the width every 4 inches. Some times 2 to 3 depths to clear out the concrete. Would defenatly recommend

I used these for cutting paving slabs. Easy to use.

I bought these after reading the reviews and they sounded ideal for cutting my indian stone. Unfortunatley they struggle to cut indian stone or harder concretes and the result is a lot of sparking and jumping.As also mentioned by another reviewer on here the instructions are also wrong, as they were for me. They say to fit the blade one way but i found they work a lot better on the opposite direction and the results were they cut through breezeblocks like cheese.If you are buying these for softer stones like breeze blocks and some softer stones or cement they should be fine and a great price to be honest but if you are looking to cut harder stuff like indian sandstone these will really struggle. I ended up purchasing a £13 norton blade from screwfix which featured the fact it would cut harder sandstones on the packaging and it was right it cut through them much easier (similar to how these cut through breeze blocks).Hopefully this review will help you to decide wether to purchase these for your needs and remember as others have said if they struggle to cut on some stones, fit them reversed.Overall cant complain at 3x discs for £9 but its more of a case of quantity over quality here.

good.
