Precision-engineered rotors and stators.

Dyna-Drill® maintains the industry’s latest and most sophisticated Weingartner milling equipment to precisely contour rotors of indefinate lengths, and produced for specific project applications. Rotors are 17-4 stainless steel and chrome plated for maximum wear and erosion protection. Stators incorporate NBR and HSN elastomers to address the varying requirements of aggressive drilling conditions. Dyna-Drill® verifies every rotor profile using a CMM and proprietary contour measurement software.
