1.new type & high speed
2.diamond core drill
3.suitable for mineral deposits & geological well
YF-HH-44A core drilling new type of product with enhanced capacity, is a kind of hydraulic-driven, spindle, diamond-bit, small-diameter core drill with fairly powerful drilling force. It is mainly suitable for exploration of metal or non-metal solid mineral ore bed. It is widely applied in core drill with diamond bit or hard tungsten-carbide-tipped bit and diamond bit in the field of geology, metallurgy, coal mine, hydrological and engineering drilling. It can also be used in the fields of superficial-zone petroleum and natural gas mining,mine workings ventilation and water discharge tunnel drilling as well as foundation pile construction in large diameter. It is in reasonable structure,light weight, powerful capacity, multiuse, steady performance, high responsibility and high standardization and generalization.
2. Main Features of YF-HH-44A
1.There are more speed grade (8 grades), reasonable speed range and high torque while low speed. Max. torque is up to 3200 Nm (2358 lbf*ft). The drill is adapted on core drilling with tungalloy-carbid-tipped and diamond oil as well as engineering geology exploration, hydrology well drilling and basic pile engineering.
2.With large spindle I.D. 93mm(3.66 inch), the drill is fed with double hydraulic cylinders with much longer stroke up to 600mm(23.62 inch). With strong technological adaptability, the rig can be adapted on many field, especially on large diameter drill rod drilling, (upper part coring) extracting core with wire line. Thus it is more effective in improving drilling efficiency with less faulty in hole.
3. With powerful drilling capacity, the rated drilling depth comes up to 1,000m(39.37 inch) with 71mm(2.80inch) wire-line coring drill rod.
