Screwfix Drill/impact driver deal
 

Hi all,
Taken delivery of a Screwfix deal of drill & impact driver.

http://www.screwfix.com/prods/79355?ts=85377

No probs with the gear, they do exactly what I want them to do apart
from the screwdriver bits, they strip of ever so quickly!
Can anybody recommend a good quality decent make of bits that will stand
up to normal use, or are they all made in China from ****ty mild steel

Same page. Wera, Wiha or Snap-on.

Is it the drill driver or the impact driver that shags the bits - or both?

Two schools of thought here, buy expensive bits like Wera, Weha. IME these
tend to shatter rather than strip. I gave up on them after a while. Option
2, buy relatively cheap bits & bin them as soon as they start to strip.
Thats what I do.

Before I got my autofeed I reckon that putting 1500+ screws into a deck with
an impact driver would shag 3 or 4 cheap bits.

Screwfix had some DeWalt ones on special a while ago, so did Wickes. Wickes
'gold' ones aren't too bad for the price.

Just a point, don't use a PH bit on a PZ screw or vice versa - shags the
bits in no time.

Only used the Impact so far, great for coach screws in sleepers

Will take a stroll down to Wickes and try theirs

Yes, that was one problem, the other I found out is to use the correct
size of bit for the screw, that's what I get for trying to rush a job in
the pouring rain.

Ok I'll admit to not knowing the difference between a Pozi and a philips as
they just look the same to me and all seem to go in regardless of what bit I
use. What is the best way to differentiate?

They're normally marked PZ or PH. If you try a new one of each into a new
screw by hand you'll feel the correct one fits better.

IME it is always stamped into the side of them - exact characters vary -
PZ2 or PH2 - or similar.

To avoid mistakes, esp. in the dark, rain, dirt, etc., I wish they were
colour coded - had thought of marking them with a bit of paint - but
never did decide which colours/what paint. :-)

Hypothyroidism is a seriously debilitating condition with an insidious

Although common it frequently goes undiagnosed.

You could buy plain steel for one and 'titanium' for the other.

And for the screw, pozi have star shaped lines on the head of the screw,
amazing what you can learn when you have to

Explains the key differences. Look for the lines on the top of the screw - if it
hasn't got them then it's not pozi

Yep but can no one tell what type of screw the bit (or screwdriver) is for
when it hasn't got PH or PZ markings? Tis very simple and a damn sight
quicker than looking for the marking.

The part and markings at 45deg to the X are a good clue.

On the screw head yes but not on the driver.

The best one is to line the bit and screw up and see if they stay in
line. This will confirm size and type more accurately.

True enough but you've looked at your screw and it has the X on the cross.
You have two screw drivers without PZ/PH markings. How do you know which
is the pozi one *without* checking the fit?

For ordinary screwdrivers buy the Wickes ones - the Pozi have blue handles,
the Phillips have red.

For bits you can usually see the X on the tip.

But how do you know the right "size" - my general rule of thumb is to
stick a PZ2 in (providing its a PZ screw), but I don't know how to
tell whether to use a PZ1 or a PZ3.

You look at the sides.. the pozi has parallel faces and the philips has
tapered faces.
Its the parallel faces that makes pozi less likely to pop out.
The extra corner nicks in the screw head are to clear the bits left by the
grinder on the screwdriver blade, although with modern manufacturing methods
you don't always get those leftovers on the blades these days.

Nope and only works with that brand of tool. My red handled screw drivers
are flat bladed...

I think you mean screw heads rather than bits?

Most "normal range" PZ screws are PZ2. Big ones say from No.10 (No.12?)
and up are PZ3. PZ1 from No.4 down?

The fit of the bit into a PZ head is fairly positive provided the driver
and head are not baddly worn. The point of the driver should fit flush
with the head not disappear into it (PZ1 or 2 into PZ3) or sit proud (PZ3
into PZ2 or 2 into 1).

That is not quite as clear as...

I've yet to see a PZ bit that didn't have the corner sections in. I was
under the impression that they were part of the design rather and a
manufacturing restriction.

I'm talking bits/driver not heads... Though I guess you can peer onto the
end of the bit/driver to see the fillet in the corner of the driver but
that isn't necessary.

They are caused by having to have the grinding wheel at 90 degrees to the
shaft.
Its damn difficult to not have them using grinding wheels to shape the
blade.
I believe I saw some that appeared to be forged to shape and they didn't
have the leftovers.
