Flex shaft heats up

[sw123man]

I noticed the flex shaft was getting hot to the touch,so I followed the direction and lubed the shaft.the next week when I was carving it was heating up again.I just replaced the shaft las july and have not done that much carving.I also noticed that the bit was leaving burn marks on the wood.any suggestions would be appreacated.

Try a new bit and see if things cool down. Also make sure that the core is free floating. Each square end should slide easily in and out of the square holes in the motor and spindle.
