Product Description
Cross Bits for Rock Drilling Working
Our cross bits diameters are from38mmto127mm, and different type are available, like R22,
R25,R32, R38, T38,T45,T51,ST58, ST68,etc
.
Feature:
1. Excellent drilling penetration
2. Used in very hard or hardest rock formation
3. Adequate for various construction conditions
4. Strong corrosion resistance
Application:
1.The cross bit is suitable for digging of very hard rock formation, hard formation and crack-grown formation.
2.All cross bits have to be reground at regular intervals to crush rock efficiently.
