• Professional Core Drilling Rig: It is equipped with a powerful 1900W pure copper motor, which provides stable output and excellent durability. It has a standard 1-1/4-inch threaded spindle (equipped with an adapter to facilitate the use of a wider variety of drill bits) and a rotational speed of 1900R/MIN. It is started by a stepless speed variator and is equipped with an overload protection clutch and a start plate lock key function. It supports drilling holes with a diameter ranging from 1 to 5 inches and a depth of 14 inches. With its compact size, it is convenient to carry and operate outdoors, making it the ideal and first-choice tool in the industry.
• Stepless Speed Variator: It adopts stepless speed variation for starting, which won't cause hand shaking. The rotation speed can be controlled within the range of 0~1900R/MIN, meeting the rotation speed requirements of work. You can control the appropriate operation rotation speed according to different materials or the diameter of the drill bit. Please start with a low rotation speed at the beginning, which makes it easier to operate the drilling rig and accurately position the center of the drilled hole. In addition, a start plate lock key is also configured.
• Safety Clutch: It is equipped with a safety clutch with an overload protection device. When the load is too heavy or the drill bit gets stuck, the safety clutch will trip automatically to protect the motor from burning out and prevent the user from being thrown by the recoil. This device is specifically designed for safety and provides effective protection for the user. Come and experience our high-quality tools firsthand.
