Great 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 outlet 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 outlet 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 outlet. 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 outlet, 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 (click the Options tab of T-35 or T-65 for more information) 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 outlet 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. See the attached cost comparison sheet between T-fitting and T-DRILL branch.

- No more costly tee fittings.
- No need to cut main line to insert fitting.
- Reduces labor by 60% by eliminating 2/3 of joints.
- Most reliable joining method.
- 30 year track record of proven technology without litigations.
- Tested and documented structural integrity.
- Approved method with over 24 codes and compliances.
- Accepted by the highest criteria like military and NASA.
- Excellent flow characteristics.

The powerful T-DRILL Models T-35, T-65, PLUS 100 Cu, HFT-2000 have all the labor saving capabilities that have been experienced by T-DRILL users for over 30 years! Whether it is K, L or M copper – ½” outlets to 4”outlets on tubing ½” to 8” – Unlike some other joining methods, T-DRILL complies with the Codes and Standards you need to meet – whether it is the UPC, UMC, IPC, IMC, ASTM or ASME B31.9.

This method is a standard of the industry. If a comparison is made between the lobor of a wrought copper tee fitting and T-DRILL you will see a dramatic difference. This is documented in most any labor calculators.:
