  • "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 drill bits and now carry them with me everywhere, awesome kit."

  • 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.

  • 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..
