Product description

Instructions for use:

1. when for drilling, first locate at a 45 degree angle, and then slowly turn to the right to drill in (to prevent slipping).
2. When for the hole opener, add water while drilling for cooling to increase the life and prevent the product from breaking.
3. It can be used for various drilling machine; do not use the impact stop of electric drills to drill holes.
4. It is used for drilling hard materials such as stone, glass, concrete, etc. The service life of dry drilling is shorter than that of adding water.


Thicker sandblasting, durable
Thicker sandblasting, uniform coating, improve the wear resistance and life of the core bit.
Nickel plating process + large chip slot
The surface cut resistance is greatly reduced, and the large chip slots make chip removal smoother and improve efficiency.
Universal drill shanks are widely used
Compatible with all major brands of electric drilling machine, strong applicability.
Simple bagging, cost saving
Our drill bits are packed in plastic bags with cartons.
