Today I got sent a mini-catalogue from Screwfix. One of their Autumn
Special "offers" was a Bosch "2kg SDS Plus Rotary Hammer" drill.

Is there any significance in the "2kg" bit (actually detailed as
2·4kg)? Possibly a larger mass will effect more forward thrust in
hammer mode?

EMNTK...

It tends to be used as an example of the type of SDS machine. 2kg is a
light duty machine, 5kg is more like a small breaker etc. I suppose it's
how hard they hammer.

There are 4kg models from Bosch and others as well and these will
impart more energy to the workpiece as you surmise. OTOH, they are
heavier to hold and work with for long periods.

A 2kg will do most jobs in terms of drilling and chiseling that you
might want to do around the house and would be reasonable up ladders as
well. A 4kg might be too heavy and unwieldy in those situations.

I bought one of the Bosch 4kg models because I wanted to break up some
paths at the time and because I wouldn't use an SDS of any kind on a
ladder anyway - not all that keen on ladders at the best of times, so
for me the heavier weight was OK and more suited for what I wanted.

Thanks Andy. If I ever want to break up any paths, an ex-colleague has
a large Kango hammer and 110V transformer which I could borrow any
time :-)
The 2kg Bosch would appear to be adequate for my purposes - even up a
ladder ;-)

At present I have an ancient B&D ½" reversible drill and a Bosch
cordless 10mm reversible hammer drill (as well as an assortment of
Dremel and "similar" miniature chamines which I use for electronicy
things).

Oh - and a carpenter's brace which I received as a 10th birthday
present a while ago.

I'm looking at an SDS for knocking back plaster/think artex to brick, to the
entire 1st floor of a house we're buying, ready for the plasterers.

Seen this for £25.00 with 3 year warranty
http://www.diysupply.co.uk/product_i...oducts_id=1086. I've
purchased silverline hand tools before. ANyone purchased power tools?

It tends to be used as an example of the type of SDS machine. 2kg is a
light duty machine, 5kg is more like a small breaker etc. I suppose it's
how hard they hammer.

How much they hammer is dictated by the impact energy (and the number of
blows per min) rather than the weight of the drill. Most heavy cheapie
SDSs have about the same impact energy as the good quality 2kg ones (2 -
3J usually). A good quality 5kg class machine will however have more
impact energy (3.5J +). Obviously as you raise the impact energy you
also increase the recoil. So if you desire lots of impact, then there is
advantage to a heavier machine.

"Light duty" is a bit ambiguous. Certainly a 2kg SDS is meant for
lighter jobs, but a good one will do heavy duty on such jobs.

Since the OP has access to a Kango hammer when needed, a 2kg SDS looks
like the right choice - and since he is upgrading from a conventional
500W hammer drill, it's going to amaze him.

Do read the FAQ, Frank. You need: hammer stop; reverse; good slow-speed
control; rotation stop that is lockable in several positions; and above
all, a safety clutch.

No, but then I don't imagine that Bosch cordless SDS drills could be
bought for £70 either.

You might have been thinking of this one:

http://www.klein-toys.com/wEnglisch/...nie/8405.shtml

although

http://www.klein-toys.com/wEnglisch/...nie/8416.shtml

could be better value for money. Note that this one has a saw with
it as well, and you would be quite safe with it where plastic pipe is
involved - no risk of a repeated embarassment.

Alternatively, this one

http://www.klein-toys.com/wEnglisch/...nie/8408.shtml

comes with a cap and a belt as well.

Don't forget

A figment of dribble's imagination that he likes to lay down before
talking to Andy. Probably because he realises he is about to get walked

Dribble is terrified of using his real name - probably something to do
with Rogue Traders, Trading Standards or county court judgements - and his
tiny mind transfers this to others.

Could also be to save others checking on his outrageous claims as to his
'qualifications'.
