What is the difference between a straight drill bit and a cross drill bit?

Cross drill bits belong to wind drills, because the blade is designed to be cross shaped and named cross drill bits. Cross drill bits are mainly used for drilling blast holes, such as rock holes, coal holes, and concrete ymjt02 soil holes. Cross drill bits are used in conjunction with B22, B25 air drill rods and rock drills. The combination of ball tooth drill bits and hydraulic rock drilling trucks is the best match for modern rock drilling technology.

Straight drill bit, also known as wind drill bit, is used for rock drilling and crushing. Mainly used in coal mines, tunnels, etc. It is used in conjunction with B22 rock drilling rods.
