How do I remove the sds chuck to fit the standaed chuck

SDS drill - the usual process of pulling back the outer sleeve of the SDS chuck should release either the bit or the chuck shaft so it virtually falls out or it can be easily withdrawn by hand - usually...

Some SDS attachments tend towards softness and with extended use can mushroom internally making them difficult to remove and sometimes nearly impossible. Twice I had had to resort to some serious brute force to remove SDS bits after heavy use.

hi
where the sds chuck is inserted slide that part at the same time you pull the sds chuck out

There are SDS type chucks, both key and keyless, available commonly. Any large hardware store or specialist power tool shop will have them.

Allways In a bench vise not allways a demolition hammer has a chuck but most times a locking sleeve for sds but allways you can remove it .

You have to remove the striker bolt from inside the spindle first. to do this remove the internal circlip (not always easy) then you can tap the striker bolt out and then press the broken bit out.

Look at the drive shaft under the base of the chuck and look for flats on the shaft or a nut. Hold this and use a pair of multi grips on the chuck to unscrew it from the shaft. Or place a bolt in the jaws if they still work and place the bolt in a vice and undo the shaft off the chuck

you can buy an SDS chuck that gos into a normal drill chuck,, it cant spin in the normal drill chuck as its got a hexsy drive on it its a much cheaper way to go and will fit any other drill you have or will ever get

Youcan only use standard drill bits with the use of a chuck attachment with the SDS type bayonet. These hammer drills use an SDS type drill bit which just pushes into the fitted chuck and are released by pulling back on the lock mechanism on the chuck.

the rubber cap in the sds chuck nose is only snap tight try to remove and dismantle the retractable locking pins.

The adaptor you need to convert your slpine to SDS-plus is Bosch part# HA1020. Hope this helps. Dave
