Drywall Dimpler Drill Bit - 10 Pieces Drywall Screw Setter Drywall Dimpler Magnetic PH2 Bits Drywall Bit Set Phillips Screwdriver Bits Set for Plasterboard Screws Depth Stop

A standard PH2 bit in a shroud to restrict driving depth saves the 'overdrive' that as a DIY'r is easy to do. But many screw joints benefit from stopping before fully set and a finish by hand driver. So a fine and value set of bits. review of item: Candeon Drywall Dimpler Drill Bit - 10pcs Drywall Screw Setter Drywall Dimpler Magnetic PH2 Bits Drywall Bit Set CROS Screwdriver Bits Set for Plasterboard Screw Depth Stop Limit

Basically these bits allow you to put screws into drywall/plasterboard at the precise depth needed, the out cone sets the depth and the screw wont be driven in any further. Ive used a drywall driver before where the screw driver just stops screwing in the screws, but this one is a more manual process. This one achieves a similar result, but It uses a static size of PH2 bits and when the cone touches the board thats your signal to stop drilling. The bit are fairly straight forward and should work on pretty much any screw driver. the quality is nice and solid and seemed to work well. They are cheap and cheerful, you get 10 bits for £6.19
