Machining tools that earn
their place on the rig.

ASI Oil Tools machines downhole tools and precision components for oil and gas directional drilling, out of our shop in Houston, TX. Our product line includes mule shoes, rod screens, slotted screens, drill pipe screens, centralizers, inner and outer rings, and fishing necks, all machined from high-strength stainless steel and alloy bar stock built to perform in demanding downhole conditions.

We handle prototype and production machining with fast turnaround and competitive pricing. Send us a drawing, a sample, or a part number and we’ll quote it and get to work. We machine complex parts from virtually any material, whether you need one piece or a full production run.

Beyond machining, we coordinate straightening, grinding, heat treating, coating, plating, and material purchasing so you get finished parts, not semi-finished blanks. Process certification is available on request.

We supply oilfield operators and service companies of all sizes, including Fortune 500 companies.
