DF-Y-5A mining core drilling machine, vertical and inclined hole drilling

I. General Introduction

DF-Y-5A CORE DRILL 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 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.

The machine is fit for engineering works of inclined and vertical hole drilling. It is compact in construction, 

rational in overall arrangement, moderate in weight, convenient in assembling and wide in range of rotation 

speed. Equipped  with water brake, with high hoisting force, DF-Y-5A CORE DRILL is convenient to  operate in low-position and with water brake application.

II. Main Features

1. There are more speed grade (8 grades), reasonable speed range, with low speed but high torque. The rig 

is adapted for core drilling with tongalley-carbide-tipped and diamond bit, as well as suitable for engineering geological exploration, hydrological well drilling and basic pile engineering.

3. With powerful drilling capacity, the rated drilling depth comes up to 1,300m(4,264 feet) with 71mm

(2.80 inch) drill rod with wire line coring.

4. Light in weight, the rig can be dismantled into 10 parts easily (the biggest one 450kg equivalent to 992 lb). 

The rig weighs 3,100 kg(6836 lb) (without power unit). It can be moved easily especially in mountain area.

5. The hydraulic chuck adopts one-way oil supply and equipped with hydraulic lock. The chuck is powerful  and stable in clamping.

6. Equipped with water brake, the rig is steady and secure in deep hole drilling.

7. Compact in structure and reasonable layout, and all exposed outside, non overlapped components, it is 

easier for maintenance and repair.

1. Provide factory cost accessories all year

2. Engineers are available to service machine overseas or free training in factory

3. Online service 24hours*7 days

4. 12 months quality warranty for main body.

How to choose a suitable machine?

1. What will you do using drilling rig? 

-For water project, core sample, soil test, mineral prospect or others?

2. The depth you need?

-For water well, generally, 30-200m. For core sample, 30-600m, even more. 

3. Any requirements to hole diameter?

-Within a certain range, the smaller diameter, the deeper depth. Mathematically, we call it inversely proportional.

4. Working land condition?

A. soil, sand, weathered land, etc. soft stratum.

B. soil, sand, soft and hard rock stratum, mixed one. 

C. Mainly hard rock, like granite.
