Lg Steel Tooth Bits

It can receive higher WOB and faster rotary speed than conventional roller bearing bits .It is suitable for high RPM applications.
Recommended Drilling Parameters. Our offered range of LG Steel Tooth Bits is available with following specifications :-

IADCWOB(kN/mm)(bit dia) RPM(r/min) Applicable Formations
115 0.3--0.75 200--80 Very soft formations with low compressive strength and high drillability,such as clay,mudstone,chalk ,etc.
125 0.3--0.85 200--80 Soft formations with low compressive strength and
high drillability,such as mudstone,gypsum ,salt,soft shale,soft limestone,etc.
135 0.3--0.95 180--80 Soft to medium soft formations with low compressive strength and high drillability.such as medium soft shale,
hard gypsum,medium soft limestone,medium soft sandstone,soft formation with harder interbeds,etc.
215 0.35--0.75 180--80 Medium formations with high compressive strength ,
such as medium soft shale,hard gypsum,medium soft
limestone,medium soft sandstone,soft formation with
harder interbeds ,etc.
Note:The upper limits of WOB and RPM in above table should not be used simultancously.
