After my first-ever session with an SDS drill, I've discovered that the chisel-bit seems to be stuck immovably in the chuck. I followed the directions with great care, lubricating the shank before I started, and breaking off mid-job to renew the grease - but clearly I should have had more breaks and more lubrication.
Any suggestions as to a painless way of removing the chisel would be very welcome.
