What is the difference between these two types of drill? I have always boug ht SDS+ for my ELU machine and was always under the impression that there w as a difference in the tool holders and the drills were not interchangeable . However having mistakenly picked up an SDS max drill bit and thinking I m ay have to return it, I compared it to all my other bits and then noticed t here was no difference. Went on to use it and it performed as normal.
