1. XY-44A is a core drilling machine, more rational rang of rotating is available and its rotating speed has 8 grades. With powerful drilling capacity, the rated drilling depth comes up to 1,000m with wire line 71mm drill rod.

2. The drill is aligned a water brake for Steady and smooth deep hole drilling.

3. Supplying oil with a simplex gear pump, it is easy for installation and operation; The hand-operated oil pump can be put in use to hoist the drilling tools in hole upon the power engine failing to operate.

4. It is easy to get to know the conditions in hole with an antivibration meter. Less in operating handles, the rig can be operated credibly and flexibly.

5. It is compact in construction, rational in overall arrangement, moderate in weight, convenient in assembling and wide in range of rotation speed.

Applications:
1. Core drilling with carbide and diamond bit.

2. Engineering geological prospecting.

3. Water well drilling.

4. Basic pile foundation engineering in large diameter.
