Services
Oilfield Downhole Tools
We manufacture and repair precision downhole motor parts for directional drilling applications. Our capabilities include bearing mandrels, bent housings, and flow diverters. Using advanced CNC equipment, we support Gulf Coast, Permian Basin, and Rocky Mountain operations with ISO 9001-certified quality assurance.
CNC Machining
Our 21 CNC lathes and 28 CNC mills produce complex components with tight tolerances. We handle carbon steel, stainless steel, and exotic materials for automotive, industrial, and oilfield applications. Capabilities include 3D machining, turning, and grinding to meet demanding specifications.
Tool Repair Services
We specialize in remanufacturing existing oilfield tools including rotary shoulder connections and acme thread modifications. Our repair processes restore functionality to stators, top subs, and bearing adapters while maintaining dimensional accuracy and operational reliability for drilling operations.
Reverse Engineering
Using CAD/CAM systems, we reverse engineer components from sample parts or blueprints. This service enables replication of obsolete parts and optimization of existing tool designs. Mastercam software supports rapid prototyping and precision manufacturing for complex geometries.
Welding Services
Our welding capabilities support oilfield tool maintenance and industrial component fabrication. We perform precision welds on steel, stainless steel, and exotic alloys, following industry standards for structural integrity and durability in demanding operational environments.
