- Moreover, the tapered design facilitates better cuttings removal. The narrower base effectively creates a larger annulus around the drill string, allowing for improved circulation of drilling fluids The narrower base effectively creates a larger annulus around the drill string, allowing for improved circulation of drilling fluids

tapered drill string. This enhanced flow rate carries away cuttings more efficiently, maintaining a cleaner borehole and improving the overall drilling process. Consequently, operators can achieve faster penetration rates and higher quality drill holes, ultimately leading to cost savings and increased productivity.

Our fiberglass structural shapes and pultruded fiberglass profiles are made from a combination of fiberglass and thermosetting resin systems. All shapes are lightweight, impact resistant, low maintenance, non-magnetic, low conductive, and have dimensional stability, making them easy to install and ideal for several applications. Custom shapes are available upon request. For more on fiberglass structural shapes, click here.
