Bosch GBH 4 DFE Multi Drill

Post by **ultimatehandyman** » Thu Jun 29, 2006 6:17 pm

The bosch Multi drill is the mother of all DIY drills.

It's a large drill and so using it in confined spaces or up ladders is very difficult. The safety clutch is a useful feature, although it tends to make hard work of using diamond core drills.

2 chucks are supplied as standard but I only ever use the SDS chuck. The machine is powerful and can make light work of most jobs. Rotary stop means that you can use the drill for chiselling and apparently you can use if for punching nails in.

I bought the drill off ebay as I had seen them for sale in several places but could not justify the almost Â£300 price tag.

The only thing you can't do with the drill is put screws in! I have not tried to chisel wood with it yet either.

Here is the full spec-

.Power input 750w
.No load speed 0-650rpm
.Impacts per Minute 0-3950
.Single impact force 3.5J
.Variable speed
.Maximum Drilling Capacity with SDS-plus Bits (Concrete) 4-30mm, With Vacuum Bits & Dust Extraction 24mm, Maximum Drilling Capacity using chuck in Steel 13mm, using chuck in wood 30mm, Recommended Drilling Range 8-24mm, Drilling performance in concrete 8-24mm
.Supplied with 1/2â€

UHM,

Are you talking about the GBH 4 DFE?

I love mine and have used it for everything, including chopping down a tree with the wood chisel you haven't tried yet.

It takes a pounding and gives it back just as hard.

Agree it's a bit heavy but that means it'll last.

Get my vote as an essential tool for the serious DIY'er.

Yes, that is the one.

I had to dig it out to check

It's a great piece of kit

I've had the GBH4 for a goodly few years now and have worked it hard. From accurately drilling 5.5mm holes into concrete lintels for curtain track to core drilling 200mm dia it just does the job without fuss. One of my favourite tools for it is the chasing bit for chjasing out where cables heve to run under the surface of a wall.

Please don't ask to borrow it as having me laugh in your face may offend! :)

I used the standard chuck on this machine last week and found that, although the chuck is a fine piece of engineering it tends to wobble a bit!

I have used the Jacobs type chuck on mine on many occasions and never have had it wobble ..... are you sure it was plugged in correctly? If it was I'd be inclined to have it looked at under the guarantee if its still valid.

I'm sure it was fitted correctly as you can't really get it wrong. I'll try it again when I have the time
