Rated 4 out of 5Â by davegl good for piloting
I had bought the dewalt blue 'concrete' screws (70mm) and the instructions said to drill a 4mm hole - this was the only drillbit i could find..but its only 75mm so not able to drill the depth needed without lifting the timber (I was trying to fit decking to a contrete ledge without lifting it)..more than 5mm needed in the chuck..
The dewalt screws were a failure, so I needed to fit rawlpugs.This drill acted as a good pilot hole to 'spot' the location and has survived 10 holes with a ryobi 18v hammer drill and mains hammer drill.
When fitted in my mains hammer dtill it went through the concrete and into brick underneath.

This drill bit burned out after drilling one hole in brick. I drilled in 10 second bursts, letting the bit cool before restarting.
Don't waste your money. Pay a little more for a quality brand.

Ive only used it to finish off a job that broke my old bit, this finished it fine, and was cheap.
