Hi-Spec 44pc Impact Drill Driver Screw Bit Set with Popular PZ & PH Sizes. 1/4 Hex S2 Screwdriver Bits with Nut and Socket Drivers.

Good little set and seem to be very well built. They tend to strip screws rather than the screws stripping them like on other cheap kits.

Fantastic set,high quality and excellent value

A nice compact set of bits

Absolutely superb has been well used moving into our new home would recommend for all us women to have a set

Complete set of impact screw bits received. Only it doesn’t fit to the Impact screw.Great service.

Bits themselves are good but the bit holder stripped itself on the first use, definitely happy I already have an impact rated bit holder made by a Swedish tool company in the 80s

Compact, lightweight and very useful.It’s selection of accessories is good and prevents the need for carrying surplus parts.

Since I own an impact driver I thought I would buy a set of impact rated bits, I wasn't keen on spending a lot on bits since I rarely use an impact so I settled on this Hi-Spec set.I am happy to say that these are impact rated, I put together some palette wood garden planters with it and my Phillips bit happily drove wood screws in without shattering.Despite that I can't say the same for tradesmen who may use an impact for more heavy duty purposes like driving lag screws through denser wood. I haven't used my bits for long and the thin protective black coating is starting to wear off on my Phillips bit. I would maybe go for a nicer set for heavy duty tasks.I do enjoy the variety of bits though, some more expensive bit sets use more generalized and standard bits and it's in a quite compact box which is great for portability.
