Jining Hengwang Mining Machinery Co., Ltd.

 Professional sampling core drill   

 Features:

1. This model can use normal straight handle drill bit or oblique handle drill bit to drill holes. And use tap bit to tap thread.

2. The drilling capacity is from  10~30mm

3.The up/down transmission of the tool bit is by the round shaft gear rack, so the drilled holes and the tapped threads won’t skew to one side. The processing quality is very good and the machine body is stable and durable too.

4. The sleeve of the drill bit and the torsion fixture of the tap bit are all speedy connecter designed which can be exchanged quickly to increase working efficiency.

5. Tapping adaptors with torsion control, tap bits are protected from being twisted off.

6. Special desigh of tapping handle makes tapping operation easier, any time you need right direction rotating for tapping or reverse for withdrawing just push it downward or release, even tap on a high hardness steel, this machine can attain it"s function perfectly.

7. With circuit protection of breaking for motor, once any wire of three phases power source is broken off, this unit could cut off current to motor to prevent motor from being burn out

8. It’s most suitable for the drilling and tapping process on the heavy duty machine and the machine-tools.
