APPLICATION SCOPE:
Diamond core drill, also known as engineering thin-walled drill bit, water drill bit, hollow drill bit, the use of water must be used during the process, can be used for large-scale drilling, boring, coring projects. It is recommended to use a fixed drill or a hand-held rig. Diamond drills have good drilling stability, high speed, and long service life.
PRODUCT ADVANTAGES:
Diamond core drill is mainly used in buildings, water, electricity, heating, gas, air-conditioning pipe installed wall holes, highways, airport runways, bridges, tunnels and other basic engineering drilling.
The diamond core drill has the advantages of fast drilling speed, high efficiency, comprehensive cost performance, good wear resistance, and long service life. The drill pipe is made of 45# steel and it is not easily deformed.

DETAILS:
Sharp formula design for all kinds of reinforced concrete, brick wall drilling, fast, high efficiency. High-quality steel body material, high-frequency welding process, high cost performance.
The use of high-quality diamonds and high-quality metal powders are specially designed for various kinds of marking reinforced concrete punching design formulas, with high drilling speed and long service life. Fully automatic laser welding process, the cutter head is firm and firm, and it is not easy to drop teeth. Concentricity is good, to ensure that the drill bit swings little when working and the hole punching accuracy is high.
FAQ & PRECAUGIONS:
Before drilling, the operator shall select the appropriate level of engineering drill bit according to the material of the hole opening object;
When drilling with engineering drills, it is necessary to add enough water. If water is not added, the drill bit will burn and the teeth will be lost.
Artificial knocking or application of external force at the welding of knife teeth and knife teeth can cause deformation of the steel body at the welding site, resulting in tooth loss and tooth decay.
Engineering drills can drill holes on grinding wheels or rough bricks when the drilling speed is slow.
After selecting the rig, first check whether the main shaft swings, whether the electrical and mechanical parts are normal, and when the drill is put on, ensure that the main shaft of the rig is tightened and kept concentric.Diamond Core Drill Bits Made in China
