Brenda A: I got this set of 5 drill bits last year in July to remove a broken bolt on my elliptical. The extraction was perfect - the center punch allows you to drill in the center of the bolt. Exactly one year later, another bolt broke off my machine (not sure if I'm breaking it with my almost daily overzealous use or NordicTrack could've built this freestrider better...) and I used the same trusty kit to remove that bolt. The tip broke off one drill bit during the last use, but I used another drill bit to start the hole, then proceeded to use the still sturdy slimmer bit to finish drilling. The HART easyout kit I have works perfectly with this drill bit set. Very satisfied customer. P.S. To any ladies reading this review --> we can do it!🙋🏽♀️

HappyPopHappyPop: Used the 3/4 universal bit to drill a 3/4 hole in the tube steel of the roll bar to run the wiring harness in.
They worked flawlessly.
Then drilled a .092 hole in the plastic to receive the on off switch.
Perfect hole and clean.
Both holes were surprisingly clean no burrs.
