Sandvik recently introduced the RR441 rotary bit with an advanced cutting structure design. The RR441 is an improved version of the RR440, designed to last up to 140% longer than comparable rotary bits. With an extended bit life and fewer bit changes, the RR441 maximizes drilling uptime, providing lower cost per meter and setting a new industry standard. RR441 sizes range from 171 mm to 406 mm (6 ¾ in. to 16 in.).
