“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.”

“These drills perform exceptionally well. They’re far superior to anything I can buy locally. Delivery is extremely fast. I was able to finish drilling a 3/8” hole through 1-1/4” hardened bar stock. I must have gone through a dozen conventional cobalt bits before purchasing this kit. Love ‘em.”

The boards would have to be secured to the cinder block, meaning we needed to drill into the cinder block. We bought our supplies (which included masonry screws and a masonry drill bit) and started the project, thinking this would take no time to complete.

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.

“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.”

“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!”

We returned our hammer drill and we got the Bosch Rotary Hammer Drill with a drill bit. Then, after saying a few prayers, we tried the rotary hammer.

But again, hours later, we only had 10 finished holes drilled (this worked better than the regular drill but still not easy).

We continued using this process for a few days, not getting anywhere. Except maybe getting more frustrated and worried about how we were ever going to finish our whole basement.

But then we got a big slap in the face. After hours of drilling into the cinder block, we only had about 4 finished holes. You can imagine how frustrated we were.

One day, my husband and I decided to insulate one of the rooms in our basement (really just a closet). After some research, we chose to use foam insulation with 2×2 boards.

Autodesk Inventor CAM is an integrated 2.5 to 5-axis CAD/CAM programming solution for Inventor and SOLIDWORKS.

And yes, we were using the correct drill bit for the job.  We even switched drill bits often but after about one hole, the new bit was shot.

We completed 3-4 holes in the time it took us to complete one with the regular hammer drill. And it was even easier to use!

UPDATE: We are still loving this drill. We have used it to drill holes through brick & concrete and also remove tile – this thing is amazing for demo! I would recommend it to anyone

Let’s start with a little backstory on how we came to know this and finally learned the easier way to drill into cinder block.
