Erbauer Countersink 12.7 x 70mm
Brilliant drill bit
This has to be one of my best purchases from screwfix.
Don't need to keep changing from a drill bit to counter sink when can get it all in one!

Very sharp useful to drill pilot hole and countersink in one.
Built large garden bench with 100 plus holes in seasoned softwood, just as sharp when done as at start.
From other reviews kept the drill speed low to not over heat the bits.

Â£3= saves you buying a new driver just for counter sinking.

Bought this as making a log store out of tanalised wood. It saves time changing from countersink to drill bit for pilot holes. Wanted the screws countersunk for a neat finish. The item works better in kiln dried would, as the tanalised is wet and leaves a bit of uncut wood in the counter sunk hole but the screw takes care of that. The drill bit can be replaced. Nice and cheap too
