JSSWT Steel tooth bit with high efficiency
SWT series steel tooth bit with high efficiency can solve these problems ,with strong wear resistant teeth and fast ROP,bit can work more stably, which is more suitable for drilling in soft or middle soft formations with high rotary speed..
The size range of SWT series bit is from 8 1/2 to 17 1/2 inch ,and IADC varies from 117 to 127
.for example:9 1/2 SWT 127.
