Exploration Drilling Casing Positioning China Quality HWT / HW Impregnated Diamond Casing Shoe Bit
A casing shoe or rod shoe bits, casing bits are used to advance drill string through the overburden layer and into the bedrock, for drilling down or positioning the rods and casing tubes in overburden borehole.
We manufacture two types of Casing shoe: W-profile, Flat face profile, and can be customized .
Casing shoe inside wall is smooth and large enough to permit free passage of drill string including diamond drill bits, core barrel etc components, there are Tungsten carbide (TC) casing and diamond impregnated casing shoe, currently we only focus on diamond impregnated casing shoe, which are embedded with premium synthetic diamonds in a hard and abrasive-resistant matrix.
Main functions of casing shoe:
1): protect casing ends from distortion.
2): help casing pass through stratum to bed rock.
3): carry mud to earth surface.
4): help down-pass of casing when drill rod is in hole
