Thermdrills must withstand extreme operating conditions. From soft metals such as brass, copper; aluminum also hard structural steels up to high-grade steel or high-strength special alloys e.g. DP1000 guarantee. 

Thermdrills have a high life span and repetition accuracy made with special temperature-steady tungsten carbide. A well sophisticated sharpening technology that ensures the tool is manufactured with high precision.

Standards and Customized - for each procedure the proper tool

Thermdrills are available in all standard sizes and threads

Thermdrills can be ordered in sizes between 2.0 mm and 30.0 mm in core hole diameters with graduations of 1/10.

For procedures where the standard sizes can not be applied we offer a "customized service". Tools will be produced according to the customers needs measurements and special requests. Our quality management team will assist with all testing and analysis needed.

„form“ or „cut“

Thermdrills comes in two different versions with different functions. One is the fixed surface or collar used as a stop when inserted into the collet and to form or un-form material. The other can be used as a milling tool or to plane the material that has formed upwards during the drilling process.

  1. Thermdrilll "form"
    for the production of holes with a collar resulted by the material flowing upwards.

  2. Thermdrill "cut"
    for the production of thermdrilled holes without collars. The type "cut" Thermdrill has cutting edges to remove the material which flows upwards during the drilling process. Thus a flat surface results around the hole.

„short“ or „long“ - quick and easy drill selection

The selection of the tool is completely simple. You must only decide actually whether a tool with cutting edges required,this would be "cut" type. When a collar is required then "form" would be used. Depending upon material thickness you select then the version "short" or "long".  with the parameters

All data can be found in the drillselectiontable for each thread type and size, including machineparameters.
