TUBE BRANCHINGGreat inventions are always simple!  The patented T-DRILL method has proved its efficiency all over the world. Branching by T-DRILL is very fast and simple. Expensive T-pieces are not needed. T-DRILL process cuts the total cost of the branch even by as much as 90 %. The method is based on an extremely simple but brilliant idea. First, a pilot hole is drilled in the main tube. Then, the collar is raised from the material surrounding the hole, and the branch pipe is inserted and sealed by brazing. This is easy to carry out, because the collar is so accurately formed that when brazed, the solder flows around the joint by itself under capillary action. A branch made in this way is very strong; it can well withstand the forces the pipe network is subjected to. The secret of the T-DRILL lies in the T-DRILL head: it both drills and forms a collar. The drill core is made of special hardened steel, and the forming pins are shaped so that they do not cause any breaks or metallurgical changes in the collar, which would reduce the strength of the joint. The design of the T-DRILL head is basically very simple. It is robust, withstands heavy use and it is easy to service.  The ND-54, (see more information from T-35 Options) is a natural complement to the T-DRILL tee forming system. It cuts a half-moon shaped profile from both sides of the branch tube to provide for full flow and simultaneously presses in the dimples that rest on the rim of the collar and act as a depth stop. With T-DRILL your plumbing work is more profitable. After using it for one large project you will find out that it has paid for itself.

*) Although we have shown that the work content is the same in both examples, by using the T-DRILL method the need to cut the run pipe is eliminated and only one outlet requires brazing thereby reducing the labour content and risk of leakage. Compare by yourself!

Our cordless tube cutting tool, TC-1 cuts costs, improves quality and increases profit. It has an auto-feed for different materials and hardnesses - all done with a chipless cut. The tool also has a tube end finishing feature. It is strong, safe and efficient. User friendly chipless T-DRILL tube cutting tool TC-4 with ergonomic design is a heavy duty tool for your everyday cutting work. TC-4 offers a dry cut without exterior burrs that may damage o-rings in the fittings. PIPE CUTTING SYSTEMS - SAWING Until now a square cut on a pipe or tube was difficult to achieve. With the pipe cutter PCS 6E, PCS 8+ or the PCS 14 it is easy, fast and safe. T-DRILL's PCS range of pipe cutting machines can be used on various pipe materials including stainless steel, mild steel, copper, cast iron and plastic. The cutting range of PCS is from 15 mm to 360 mm depending on the machine. The square cut ends are burr-free and ready to be connected saving labour time and costs.  The PCS machines are powerful and lightweight. They are ideal for use by pipe fitters on construction sites and on industrial pipe installations.
