Structural features

SWT series steel tooth bit wiht 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 SWT127

HIGHER WEAR-RESISTANT CUTTER

Enhanced structure of cutter shape

Optimized structure design of cutter shape is thickened hardfacing on surface and crest of cutters to enhance aggresiveness for cutters.Enhanced hardfacing on leading edge and trailing edge of cutters improve wear-resistance of cutters.

Optimized hardfacing technology 

New welding material is used to enhance further wear resistance of cutters.

HIGH ROP

Optimized cutting structure

Based on rock mechanics features,adopt calculation and anylasis tools to optimize cutter row arrangement,parameter of cutter shape and number of cutter.Then the maximum cutting efficiency and direction of movement for cutters of each row are calculated accurately to maximize breakage area and volume of bottom hole when each cutter contacted with the bottom hole.Finally,ROP of the bit is also improved.

Enhanced wear resistance of cutters can keep longer aggressiveness,so that the bit can keep high ROP till end.

High efficient hydraulic strucutre can clean out cuttings at bottom hole and create good working condition.
