3-speed Core Drill Rigs For Concrete Construction Drilling Capacity from 1''-16''

Professional, high performance core drill rigs designed for frequent concrete / reinforced concrete drilling.

■Seiko-made gears adopt heat treatment process to improve gear hardness and wear resistance.

■The column adopts all magnesium alloy die-casting aluminum parts to ensure high precision, light weight, high strength, anti-oxidation and anti-rust.

■The stand can be tilted from 0 to 45 degrees for angle drilling, and equipped with transport wheels for easy relocation. Roller carriage allows for accurate alignment that requires minimal adjustment.

■Adopt the three-speed regulation to expand the speed range of the drilling rig and improve the working efficiency.

■The gearbox is oil-bathed with liquid lubricant to keep the gears inside the gearbox fully lubricated and cooled.

■ Gear oil meter display, very user-friendly.

■ Vacuum adsorption base, no need to install the drilling rig.Efficient and fast.

■Allen wrench  4、5、6、8、10mm

■single-Head wrench   36、41mm

■Double-ended wrench  17-19mm

■Carbon brush  1 set

The following situation is out of guarantee:

1.The commutator of rotor appear groove .

2.The engine is destroyed cause somebody wet it.

3.The aluminum part of machine(shell,gearbox,middle lid,base).

4.The engine or gear is runied by overload when running.
