Drill Collars

Matrix Drill Collars are used to achieve correct weight on bit (WOB) to maximize penetration rates while keeping the drill string in tension. We offer multiple collar diameters, lengths, and wall thicknesses to match your specific application. We are happy to work with you in meeting your drilling challenges and we’re only a phone call away to discuss your requirements.

The product range includes Wash-Down Casing, Conductor Casing, and Dual Rotary Casing. Lengths to 30 ft. We also manufacture custom casing for project specific requirements.

Subs and Accessories


Stabilizers are used to assist in providing smooth, supported rotation of the drill string. Many times a formation may be subject to significant erosion, causing the borehole wall to be unstable. Stabilizers help to support the lower end of the drill string. In addition to providing supported drill string rotation, stabilizers enhance production as they keep the drill string aligned with the drill bit. Matrix offers milled spiral stabilizers are available up to 48″ long and to 20″ OD. Straight blade stabilizers are available up to 72″ long and 20″ OD.

Hoisting & Lowering

Matrix manufacturers a range of heavy duty hoisting plugs for our large diameter rotary drill pipe in deep hole applications. Our Deep Hole Hoisting Plugs are engineered for loads up to 200,000 lbs. We also design and engineer elevator plugs to fit our customer’s specific needs. Matrix is an experienced manufacturers of custom, application specific handling tools.
