Bosch Scintilla SA Drill Chuck

[GabrielS]

I've a Bosch Scintilla SA drill, model #0 603 121 001, made in Switzerland which I cannot find any info on and also lacks the chuck. Other than that it runs great. Any info on this well made drill and where to obtain said chuck would be most appreciated.

I attempted adding photos but for some reason did not appear. Here they are...hopefully!

You could make a threaded adapter. Find a chuck you like and ask for some help here. It helps to be around for awhile for credibility but welcome nevertheless. And post your location before asking for any help.

Thank you for your reply Zeke!

That drill may have been made for the European market, and the drill arbor may be a tapered arbor like you find on some European made hand drills.

When I searched the model number, this adapter came up on Amazon spain.

I had to use Bing translate, but the description sounds like it adapts a B12 tapered arbor to a threaded arbor. The adapter is expensive, so it would probably be cheaper to find a B12 drill chuck instead. Companies like Rohm and Metabo still manufacture drill chucks for hand drills with the B taper dimensions. If you check ebay you can sometimes find them cheap since most drills in the USA use threaded arbors or morse tapers. Make sure to check the dimensions girst to make sure ut is a tapered arbor. This website has dimensions.

Thank you for the info. I measured as best as I could the part protruding from the front of the drill and found the internal thread diameter to be 7.94 mm and 1.0 mm pitch per thread.
