The suitable tooth type will be chosen,bearing structure, sealing type and angle of inclination of paws.water cutting, good sand returning can efctivele reduce sand gathering. Unique anti-faling design of cones prevent the accident caused by falling cones which is leaded by bearing damage. Perfect welding process prevents the damage to sealing and bearing system because of over beat.The bit body adopts spiral design with good stabilizing and sand returning performance to improve hole opening speed reducing repeating rock breaking of cones.Advantage? Available roller cone with sealed bearing or Metal sealed bearing? All our hole openers and rock reamers can be supplied with a widerange of cutters to deal withsoft rocklike limestone or sandstone, rignt up to hard formation bits capable of drilling in Granite and Basalt.?
