HI Can the SDS chuck on a Ryobi ERH650V be changed to a stanard chuck thank you

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sleeve of the SDS chuck should release either the bit or the chuck shaft so it virtually falls out or it can be easily withdrawn by hand - usually...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

The SDS chuck is an intergral part ot the rotary hammer drill assembly. You can get a standard chuck that has an SDS fitting on it and that will fit into your drill and give you standard drilling capabilities.

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.

go to my site and under the tips section there is a detailed description on how to remove this chuck

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

tap it lightly with a ball pin hammer, if that dosnt shake it out try opening it and useing something to push it through

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