SDS hammer drill requires too much force too insert bit.
I have a milwaukee fuel m18 SDS hammer drill 2908-20. everything works perfectly but it requires almost 15 pounds of force to insert a bit which is strange because when pulling the release collar it pop out just fine and when the bit is locked in the tool operates as intended. I have tried brand new milwaukee bits and oiled and cleaned the chuck thoroughly. I have never run into an sds hammer drill that has trouble accepting a bit but allows it to release with ease. Any tips from anyone who has mabe had this issue?
