117.5MM Steel Tooth Tricone Bit 4 5/8'' IADC217

Product Description

water well drilling drill bits Mill tooth tricone bit

Soft Formation steel toothtricone bit

For shales, sandstones,limestones and dolomites

These Tri-Cone Bits are designedfor maximum penetration rates.  Bit tracking is virtually eliminated bycombining a large cone offset, sharp chisel-shaped inserts and non-uniformtooth spacing.  Shirttail protection along with carbide leg protectionincreases bit life for HDD applications.

Medium to Hard Formation steeltooth rock Bits

For medium-hard shales,limestones, sandstones and dolomites

These Tri-Cone Bits havemoderately sharp conical or chisel inserts with a shorter extension.  Anincreased insert count helps reduce breakage when drilling in harderformations.  Full bottom hole coverage and non-uniform insert spacingresults in smooth drilling at high penetration rates.

Hard Formation steel toothtricone bit 

For hard sandstones, granites,dolomites,

quartzite and pyrites

These Tri-Cone Bits are designedto withstand high loads and drill abrasive conditions where rock is brokenunder high compressive point loads, with little scraping and gouging.Therefore, the cutting elements tend to be small, exhibit shorter protrusionand are more densely packed, which prevents the high compressive loads frombreaking the tooth before it breaks the rock.

tricone bit covers almost IADCcode,including 11 common tpes, and is with raliable quality and resonableprice,the size range is from 3 7/8" to 26",can be used for geologicalprospecting, development of oil and gas, drilling water wells,blast holes andmaking holes for seismic prospecting,construction engineering

Our tri-cone drill bits classification: water welltri-cone drill bit, geothermal well drill bit, trenchless directional triconedrill bit, natural gas drill bit, petroleum drill bit, including sliding sealedbearing series, rubber composite sealed bearing series, rolling bearing series,metal sealed series, non-sealed series, etc.

All tricone bits are accordingto ISO and API standards
