Bosch drill

Jun 04, 2010 22 Replies

My old (30+years) Bosch two speed hammer drill shed a tooth off a cog a few days ago after one of those oversize blacksmith style drill bits snarled up and stalled the drill in a nanosecond :-( A few attempts at buying spares online looked promising initially but failed do the the part being obsolete. [1]



So I need to replace it. It was a great drill without one of those stupidly unreliable trigger operated speed controllers and served me well for 3 decades. I'd like to try and replace it with as near to ''like for like'' as possible. Suggestions and recommendations please for a new drill that's built to last and will stand up to serious work on occasion like concrete drilling and 1" blacksmith drill bits.



Thanks Julian.



[1] I don't suppose anyone has the capability to make a new gear to a pattern for not too much cash?

I have to say, you want an SDS pnuematic drill for concrete drilling, but for a bomb-proof 2 speed hammer drill, I would recommend the Makita HP2010N.

I can recommend the Wolf Sapphire 76, as mine has served me well for 34 years, though availability might a little restricted nowadays

Try HPC Gears for a replacement gear. Just send them the gear and they will give you a quote

If you want to go down the Bosch Road then you should look for the Blue Series. The normal handy-tools from Bosch are of the green series and are for hobby use. The blue series are tools for proff's.

I will not comment the price for blue Bosch but if you buy a new one and use the new one for 3 decades, does the price really matter that much?

Thanks, that's useful info, the one I have is indeed a blue one which is probably the reason it lasted so well. I'll look again at Bosch, and AAMOF I've just had a round robin email of tooled-up.com offering a special price on a Bosch drill.

Silly question - have you asked Bosch if they still carry spares?

Miles Tool and Machinery Centre was who I used. Exploded parts diagrams are available on-line. First I ordered a gear assembly - reply stated obsolete after a few days. I then tried again and ordered just the cog in question, nothing heard for about two weeks so I started to think my luck was in, but then another ''part obsolete'' reply. To be honest it comes as no surprise - you can't really expect parts for a small drill after 30 + years really.

Actually yes ... and a lot of this stuff is only available from the manufacturer, hence the suggestion to try them. I doubt that anywhere other that Bosch would be bothered to hold spares.

Are you suggesting that the Bosch factory in Germany would be willing to deal with an individual living in Warrington? I'd be very grateful if you could provide some form of contact details so that I could make enquiries.

My previous experience with Bosch (fuel injectors for cars etc) has always been via an agent or distributor in the UK - I assume Miles Tool and Machinery is an agent. I'll telephone them on Monday and see what the situation actually is and what their efforts have been so far WRT spares....

HI I might be able to make a new or repair your old gear, PM me if you are interested. Peter

have been surprised in the past when looking for spares on these types of product, and I would expect third party spares sites to be doing their homework, but THAT has not been the case in the past. I've had offers of new goods when a spare WAS available and delays in replying just seem part of the 'you have to buy a new one' process :(

I tried the part numbers in that link and got no results.

If you look here:

and look for item #'s 16 and 19 you'll see what I tried to order. As you can now see, me trying to order the parts has resulted in them being deleted from the ''add to basket'' facility.

I think I've had it really, but you've got to try!

Julian.

Thanks, it's item 19 on this diagram:

What do you think, I'd say making one of these gears for a hand drill would be pretty much a crackers proposition, but if you fancy a challenge?!

Not too long ago I got a spare (speed controller) for a similar dated Bosch from GRIP Engineering in Sevenoaks. 01474 853153 Worth the price of a phone call. Sadly the newly rejeuvenated drill, whcih I also liked very much got nicked just a month later and the new replacement drill I bought isn't a patch on the olde one. Such is ever the case I fear.

Probably need that as well .... after getting a new brain ;)

Julian,

I just looked at my Bosch drill and it's a CSB 520 2E with the electronic trigger speed control. I bought it about 1985 to replace a B&D that decided to commit suicide by loosening a screw and taking out the fan blades. The only thing that's failed on the Bosch has been the strain relief on the mains lead, everything else including the trigger speed controller has been fine. The most abuse it has seen IIRC was drilling deep holes in concrete fence post footings to help break them up, that got it smelling a bit hot. It's still going. I'm quite impressed with Bosch products, I've not had one fail yet. My big angle grinder is a Metabo 5", the other is a blue Bosch 4.5" which is much lighter and nicer for single handed use. All the other Bosch stuff is green DIY stuff and seems to stand up well to my use.
