Introduction: Thermal Drilling Technology for Sheet Metal Drilling & Tapping

What is Thermal Drilling: Making Holes without Removing Material

• Drilling holes removes metal from the work piece
• If the metal is retained, the hole becomes stronger
• It can allow formation of a collar which can be tapped or used as a through hole for welded, soldered or brazen connections

Thermal Drilling Process:Formdrill tools are made from Tungsten Carbide. Their conical body has specially developed lobed geometry. Thermal drilling process is a method of making a hole and simultaneously producing a bush from the parent metal to give additional support as a bearing surface or for a thread.

Make a hole and form a bush in one operation.Frictional heat is generated by speed and pressure to form the material.Fast cycles(2-4 sec for M8-M10 holes

The completed bush gives additonal support as a bearing for a thread.Threads are produced by roll forming. No material is removed.Strong connection with no parts to break free improves joint connection.
