Triton Pozi Screwdriver Impact Bit 3pk PZ2 50mm (740013)

I was a bit wary as some of the other reviews mentioned shearing of the head. I can only venture this must be a result of poor technique, if you try and apply full power once the carriage bolt or whatever has been screwed home of course that energy has to go somewhere. I used slow speed for the final 1/2 inch to make sure I didn't overtighten, and let your hands and the drill rotate anticlockwise in the very last second to take off even more of that last force so you're not stressing the bit. I went through maybe 50 joins in an afternoon and the bit was in fine condition afterwards, with very little wear on the blacking. Good job, Triton.

Bought these as a companion for pozi countersunk green screws to put up 21 six foot fence boards vertically. They gave me such a good grip that I was able to dispense with pre drilling for the screws. Between them they put in about 150 screws without slipping once. The boards were soft wood but going into hardwood lathes. No sign of wear on the bit but cannot say how long it will last, though pretty confident it will be a while before I need to use one of the two spares. Highly recommended for quality at a great price.

As far as I can see there are now identification markings on the actual bits. So if I take it off and put it in my bit box I won't be able to tell what is at a later date.

Good item. good Value

These bits fit snugly in the screws and are pretty durable, being made from S2 steel which has the best balance of properties for this job. These are torsion bits, which means they can bend rotationally so you get less cam-out and the tips last longer. It also means they can snap if you push them into material that's too hard; pre-drilling would be wise in that case.

Start using immediately after arrival and so far so good. I use for only 50 - 60 so far but looks good. As far as I can see are not the top quality if you are planning to use in every day but for DIY hobbies I think they are perfect, especially with those prices. Yes, I do recommend

A good fit and durable

They do what's expected, but like all bits don't let them slip or it dulls the grip.
