Looking for a lightweight cordless drill driver for overhead work. Its gotta handle masonry 7mm wood 6mm and steel 3mm

was considering

<a href="http://www.bosch-pt.co.uk/boptocs2-uk/Trade+and+Industry/Tools/GB/en/gw/Compact+Duty+10.8+V+Lithium-ion/119043/GSR+10%2C8+V-LI-2/16834/index.htm">Bosch 10.8v-Li 2</a>

or

<a href="http://www.makitauk.com/index.php?special=product_detail_popup&pid=2021&catid=253">Makita DF330DWE</a>

Is one better than the other?

Or maybe even

<a href="http://www.metabo.co.uk/Product-catalogue-handheld-powertools.23958+M539f2af3210.0.html">Metabo Powermax Li Pro</a>

The metabo is the lightest by about ¼ kilo but does anyone know if it could handle the 7mm into brickwork?

Any other lightweight recommendations?

non of those are any good for masonery as they dont have hammer/percusssion action

i have the bosch so will try on a brick and conctete with a couple off 7mm masonery bits designed for cordless

forget any 10.8v

ryobi 18v hammer 35mm hole in a paving slab 6 seconds easy peasy

bosch 10.8 25 to 30 seconds strugling above 25mm

softish brick ryobi 2" 8 seconds

bosch 44mm then near stalling

Hi big-all



Oh thats a shame, dont think I could hold my old 18v Ni Cad hammer above my head and drill straight for very long



Were the masonery bits for concrete you used bosch's multi construction bits for non hammer drills? And still useless.....

I'm presuming you are not impressed with the bosch for £130 drill then? You have defo put me off buying it and the Makita for that part, Cheers for saving me that hassle, Not much point in even considering the Metabo either then

However still need to replace my ole drill for summat lighter

What voltage/weight is your Ryobi?

Any other recommends for a lightweight solution to my needs?

cheers

The ryobi is 18v, dunno about weight.

A lithium battery pack is the way to go if weight is an issue...
Power wise, 18v ones have the guts, and weigh only over 2.2kg. (hitachi)

Having a slightly more powerfull drill means it may be heavier, but it will work faster, so you don't have to hold it up for as long....

Swings and roundabouts!

Or perhaps get a lion impact driver to use for screwing/drilling, and just break out the heavy combi drill when required

i am over the moon with the bosch 10.8 it is extremly powerfull for its size 30mn of torque is very powerfull

you dont buy a mini to pull a caravan do you
http://www.youtube.com/watch?v=gQSTMYNqBW8
ryobis about 2kg including battery

theres lots off 12v gear with hammer action but its all approching the 2kg level as the the hammer action adds probably 20% to the tool weight on top off the 10% for higher power and the 10% for larger battery

Obviously not that powerful if it struggles to drill a 7mm hole 25mm into concrete. I really would have thought 30Nm was easily enough to accomplish this


Hehe fair enough the Bosch 10.8v-Li might be a mini. But 7mm into concrete hardly equates to a "caravan" more a "½ ton trailer" If that was my mini it would be going back to the dealer



Cheers for the info Big-all. least I know I don't want a piddling 10.8v anymore. What about these non hammer multi construction bits....presuming they are not up to it then on even a bigger Li-ion drill?

Cheers Hitch Liion impact driver (more Nm, nice idea) I'll look into that have you tried it?

you need hammer action for brick masonery and concrete non off the 10.8v tools have hammer action and do not say they can drill into masonery

any drill driver will struggle you need hammer action
its like asking dial up broadband to work fast its the wrong tool for the job rather than a "ineficient underpowerd" tool

you get drill drivers in 12 14.4 and 18 v they wont drill onto masonery or brick easily either

dont assume li-ion is more "powerfull" its not to any extent
it may transmit its power better with lower losses in general it can only be slightly better at perhaps 10% more overall including longevity so perhaps 5% more power for 5% longer

by far the greatest value for li-ion batterys is the ability to short charge as in 10 mins here means 55% on a 30 min charge as the empty battery has no resistance
so you can top up charge at every coffee break so 3 li-ions will = 6 nicads

Well they can.... according to Eric at BOSCH HQ (@ 5.30 of video)
<a href="http://www.youtube.com/watch?v=vx2qaZstfAQ">The man from bosch he say yes </a>

Although I admit it don't look too good at it... even with the advantage of being able to apply downward pressure on the brick (when do you ever get the opportunity to do that?)



I know what your saying and I NOW agree it is probably asking too much of 10.8volts with the multi const bits even for just the occasional 4 x 7mm x 50mm masonery job i might throw at it.



Cheers mate guess I'll just stick to hoisting my ole 24v nicad (thats why it's so heavy, its 24v not 18) above me 'ed for some time yet then

on those sizes my 12v dewalt combi drill mashes through all of what you described!

IF IT WERE EASY ITD B BORING!

it only drilled brick due to the construction drill bit, a std masonry drill ouldent drill it

http://www.milwaukeetool.com/ProductDet ... ess+System

they are industrial rated

no no no dont miss the opertunity to buy a new toy
leave your 24v with a masonary bit in
then buy a 10.8v bosch for the lighter jobs
you could even get an impact driver to keep your drill driver company

Ive actually started using my 24v sds for everything now.Ok its heavy but me arms have adapated to the weight now and saving a fortune on gym fees too .
The main reason is its so quick with hard lintels that the 18v seems like a toy in comparison.
Definately get an impact driver, so light and so much torque its ridiculous.
