Yes, it is that simple. The most complex piece of work is selecting the correct size tap.Drill the hole with the size indicated on the extractor, insert the extractor into the hole, extract screw by turning the extractor with a tap wrench or crescent wrench.
I've had better luck with the spiral type. That's why I posted them.Actually I still haven't removed the screws I cannot clamp them and this straight fluted extractor isn't working. and I do not want to ruin my planer as it is very expensive to replace. I cannot afford to send it to get fixed and have no clue as to remove these darn screws. I have even emailed Dewalt with no results. I feel more frustrated now than when it happened. there has to be some way to fix this problem without any damage
