Pack Of 2-6mm x 210mm Long SDS Plus High Performance Hammer Drill Bits, Professional Tungsten Carbide Cross Tipped Masonry Drill Bit For Brick, Concrete, Stone, Granite. 6mm SDS Drill Bit

Does the job. Good quality

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.

All good and work well

Nice quality good price.

Good drill bits definitely recommend

Perfect did what it was required 8 holes in. Solid concrete

Brilliant absolutly no effort drilling larger holes cost a little extra but made the job a lot easier

Length description 210mm including the SDS end. I.e. total length not drilling length.
