cordless sds drills

fin · Post by **fin** » Wed Jul 16, 2008 11:03 pm

specifically dewalt makita or bosch either 24 volt or 36 volt.

what are they like for general building use? would they last a full day on one charge for example?

if i was to do wall tie replacement on a terraced house (ie front and back) would they be up to the job?

what about an injected damp proof course? would they be up to drilling lots of holes before the batterys were dead/?

just i was chatting to a friend of mine today who has a makita 24 volt drill and he was saying how mint it is.

theres a dewalt i saw on ebay tonight for a shade over £200

cheers for any advice guys

If my DeWalt saw is anything to go on know it wouldn't last.

I think if you went for 36v and had two batterys you would be ok, again going on my Hilti 36v drill

or is your saw a more recent dewalt?

i weighed it up and got a corded sds...........as most jobs i do are near power, and the batteries cost £100 each

We have one we use for doing certain stuff, like thye odd 6 or 8 holes somewhere theres no elec. FOr all day use, you cant beat plug in power thought no matter what tool.

Ive got a dewalt 24v sds and there is no way it will last all day. I use mine for drilling 10mm hole to fix security gates and grilles in with.We recently did a job requiring over 100 80mm deep holes and two batteries were not enough.The 18v dewalt impact driver lasted on 1 and a bit though.
As its cordless it is usefull but not a day kit tool, more a convenience tool like when up a ladder etc.A cheapo codred will drill quicker too.

Scruff,
I worked for HILTI for 15 yrs, if you have the TE6A 36v the batts must be over £300 by now! But they are the best but I'm biased.

Steve

P.S. I have 2 Hilti's one batt 24v + one corded (for flue holes etc)

Yes I have a 110 as well, good kit there's no doubt about that, I have the battery belt where you can use the battery remote from the drill, makes it lighter if working overhead.

Used to get the battery's with a big order for about £140

I'm sure that they would do the job, but I am not sure how long they would last when being used all the time for this purpose.

SDS drills are not really recommended anymore for installing cavity wall ties as they can knock off a large section of the brick when exiting, which falls down the cavity and then can cause damp problems-

in the link it says percussion drill. ive only ever used either sds drills or the old fashioned type of hammer drill. whats the difference between these and a percussion drill?

A percussion drill is not as aggressive as a sds drill and so you will not get it knocking of the face of the brick in the cavity. The only downside is that it will take longer to drill each hole, especially in hard bricks.

Percussion = 3 jaw chuck kit - Cams that vibrate on eachother to create a vibration or " percussion"

SDS = (serious drinking squad!!) Electro-pneumatic hammer, the drill bit is struck several times per revolution (depends on drill how many)

SDS by far the best and I would use them for wall ties with care on depth guage and variable speed. That's the bit most chuck away or say " wots this for?"
