Testimonials

  • " I used one of these bad boys , and I must say it went through the steel lintel like it was wood. To really understand how hard and annoying lintels can be is a whole science in itself. I love these cobalt drill bits and now carry them with me everywhere, awesome kit. "

    Mr Marlon Wallace, Marlon Blinds Ltd
  • They are far superior to the average drill bits that can be purchased at the local hardware store. They have put much time and Research into there product and it shows in pure performance. These drill bits are in my service truck and will be for a long time.

  • "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 out on a couple 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 some more sizes or one of the sets!"

  • I ordered a selection of sizes to try them out. What a difference! A firm pressure and some jiggling with the drill speed soon resulted in the drilling of all the holes with one drill and with the same curl of swarf seen on the video. TTP might sell tough products but I found them anything but tough to deal with, communications were excellent and the drills arrived on time and well packaged I would deal with them again without hesitation and can highly recommend their products and service. Thanks TTP..

    They are amazing. Didn't believe the hype, but it appears to be true. I am a locksmith and drill hard plate on safes. They really tore into it. You don't make them in any longer lengths do you ? 6"-8"
