22mm x 600mm Long SDS Plus High Performance Hammer Drill Bits, Professional Tungsten Carbide Cross Tipped Masonry Drill Bit For Brick, Concrete, Stone, Granite. 22mm SDS Drill Bit

I purchased the (6.5mm x 160mm) bits to drill 12 fixing holes in dense concrete blocks (7.3n) using a cordless hammer drill. They were excellent. Holes were drilled quickly and cleanly with little sign of wear on the bits themselves. The bits were supplied in a useful, reuseable, twist open plastic tube.

Nice quality good price.

All good and work well

Quality product and great value for money.Looked all over to find something as effective at this length.Good durability and effectiveness thus far.

Right size / full length / 4 on quality5 🌟 on money paid for it

They do what there meant to do at a competitive price

Great did the job well. Faster than using a double tooth masonary drill. Recommended.

Not used the drill bit as yet but looks like it will do the job nicely
