Feature
A.More suitable tooth type, bearing structure, sealing type and angle of inclination of paws.
B.Water cutting, good sand returning can effectively reduce sand gathering.
C.More protection teeth on the roller cutters.
D.Perfect welding process prevents the damage to sealing and bearing system because of over beat.
E.Fully heat-treated alloy steel.
F.Unique anti-falling design of cones prevent the accident caused by falling cones which is leaded by bearing damage.
G.The bit body adopts spiral design with good stabilizing and sand returning performance to improve hole opening speed reducing repeating rock breaking of cones.
H.The customer manufactured hole opener 'OD are between 220mm to 1600mm.
I.According to the features of drilling machine and different drilling formation.
J.Professional engineers design hole opener for your drilling environment.
K.Our TCI tooth cone hole opener are promptly manufactured,we also custom manufacture reamers according to customers' special request.
