“I was very happy with my purchase of the tough drill bits, they allowed me to drill out some broken off tensile bolts form a 25 year old motorbike cylinder head, failure in this would have meant finding a new head or abandoning the project.”

“They are fabulous. I still haven’t had the time to use them for their actual intended purpose – drilling out exhaust manifold studs, but I did try them on a couple of bolts to see how they did and was very impressed! Told a bunch of my friends about them. Hoping to get a joint order together. I want more sizes or one of the sets!”

“I’ve been at this a long time and I have never seen bits this good. On my test, they breezed through gr 8 bolt on the press with cut oil. When I tested with a chord drill, I found that you could break the bit if you weren’t perfectly square. On the car with the broken exhaust stud, it was fantastic, they bite like crazy. I’m going to give them as gifts to my wrenching friends.”

We have selected some customer reviews to give you an idea of some of the hardened metals and steels TTP HARD cobalt drill bits will drill through. You will see that whether you are drilling a hardened 12.9 bolt or an exhaust manifold stud once you follow the basic drilling principles you should have the same level of success.

Watch videos of hardened metal being drilled with TTP HARD cobalt drill bits. You will see how easily Hardox 450 can be drilled using the correct speed, pressure and pleanty of libricant paste. Likewise a 12.9 cap head bolt is easily drilled when the drill bit is allowed to do the work and rest periods prevent the drill bit from overheating. Finally you will see a BMW flywheel and even JCB tow plate steel being drilled without any effort using correct speed, pressure and lubrication.
