Rated 5 out of 5 by from Good quality Good quality and value for money, I can recommend this bit the only problem is the impact driver is very hard on the screws.

Rated 5 out of 5 by from Decent ph2 bit I got one of these and its smaller brother a few weeks ago for a composite decking job with 400+ stainless ph2 screws. Originally bought for it narrowness, I was impressed by the quality and finish and it worked perfectly with only two damaged screws, one sheared off after hitting a knot and the other damaged head was entirely down to user error. The diamond tip is worn but it's still going strong as my first choice bit, even for pozi as it works so well. In fact I'm here now looking for some similar pz bits but they don't seem to do a set, or maybe Srewfix don't sell them? Anyway, a good value and decent bit that works well in my 18 and 10.8V drill drivers. The only thing I couldnt comment on is durability in an impact driver.

Rated 4 out of 5 by from Power driver bit Worth buying rather than a cheap set if you want to use them more than just the odd time

Rated 5 out of 5 by from Quality shines through After countless problems with multi-packs of cheap bits, paid a little more and the saying is get what you pay for! And in the long term you save money with a reliable product that does not damage screw heads and can be used without damage to itself!!

Rated 5 out of 5 by from Good grip and durable. Far better than buying a box of cheap bits. No more screws left halfway in or out with ruined heads, or trying to get more pressure on the bit while hanging sideways off a ladder.

Rated 5 out of 5 by from Great Worth buying these individually rather than a cheap set if you want to use them more than just on the odd occasion.
