Types of rock drill bits
We understand that every consumer has unique needs, so we offer a wide range of rock drill bits to ensure you find the best fit for your construction environment, no matter where you are.
Chisel bit
It is suitable for light rock drills to drill rock formations with low hardness and is easy to sharpen.
Cross-type and X-type drill bits
They are suitable for drilling in cracked and highly abrasive rock formations when using rock drills with higher impact power and strong radial abrasion resistance.
button bit
Under the condition of a higher impact power rock drill, the button bit has better applicability than the sheet-shaped insert drill bit and has higher rock drilling speed and service life, and the drilled holes are rounder. Our button bits include the standard button bit, retract button bit and reaming button bit.
