SledgeHammer's Spiralizor is designed specially for highly deviated or horizontal wells. Ideal for use with Liner Hangers. The steel construction ensures extra strength and superior toughness. The boat shaped Spiral fins minimize Drag Forces while running pipe. The fins glide smoothly in the low side of horizontal bore holes. Wide symmetrical fins are smoothly beveled on the both ends to have lower coefficient of friction and to ease casing movement in either direction.
