Catalog Formdrill
Formdrills 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.
Formdrills have a high tool life and repetition accuracy and are made of a special carbide.
State of the art grinding technology ensures our tools are manufactured to the
highest precision.
"Standard" Formdrills are available between 2.0 mm and 25.4 mm tool diameter with graduations of
1/10mm.
"Special" Formdrill tools can be produced according to the customers needs . Our
technical team can assist with all testing and analysis needed.
