►Main feature
1. HF-42 has eight rotary speeds and reasonable ranges of speed (please see the list of spindle speed). Max. torque is 3.5 KN•m (2580 lbf•ft) ( While With lower rotary speed of spindle).
2. With large spindle I.D. 93mm (3.66 inch), HF-42 is driven by hydraulic double cylinders with much longer stroke up to 600mm (23.62 inch).
3. With the features of reasonable power and lower oil temperature, it adopted simplex hydraulic gear pump for oil supplying.
4. Double-action hydraulic chuck is in powerful clamping force.
5. HF-42 is in the light weight, easy disassembling (for nine parts), and convenient for maintenance and repairment, due to the advantages of compact structure and reasonable layout.
6. It steadies in the high drilling speed because of its smooth movement and low centre of gravity.
