pwhole said:It doesn't sound right to me either. And there's no visual indication of hammering at the drill point - it looks as though it's just rotational drilling with no hammer. I can only imagine that the hammer is oscillating, but isn't actually hitting the drive shaft, or whatever part it hits. So you can hear it, but it's not actually doing any hammering at all.

maxf said:From the limited bolting I have done now I realise I prefer a heavier drill (3kg) that you only have to hold above your head for a short amount of time applying very little inward force to a the lighter drill (1.5kg) which take longer to drill and requires more pushing.
SamT said:Another common error is to push way tooooooo hard on the back of the drill. As someone pointed out, the impact energy is generated by the mechanism within the drill. By pushing really really hard on the back of the drill, I suspect that you are quashing the ability of that mechanism to work effectively and efficiently. I once witnessed a build bloke at work pushing so hard on the back of the drill that he was practically stopping the drill from turning. (note, this was an SDS drill, not a 'hammer' action drill where reasonable force is needed).
Imagine you are drying to hammer a nail into a piece of wood, and someone comes along and tried to push your fore arm down, making it difficult for you to lift your arm up for another blow.
The end result is slow drilling, hot drill bits and rapidly depleted batteries.

If you don't want to splash out ?1000 you can rent them for ?15 per month from your local branch and never have to worry about a drill again....... leave the toy drills at home for the shelving!

2.1j, 3.0kg (with 4AH battery), fits inside box 301 mm x 202 mm x 85 mm
Compared to the MakitaDHR242 @
2.0j, 3.3kg, 328 mm x 213 mm x 85mm

Previously UKC favourite Makita DHR165 is lighter than both at 2.5kg but is very L shaped (297x253x79mm) and less powerful (1.3J). Still fun though
Edit - I'm not 100% sure about the weight on that (specifically whether it includes the battery or not) - Google has given me more than one result quoting 2.2kg.
