Single Wall Casing Shoes
HEMCO has designed special shoes for single wall casings utilizing HBA60 and HC20 bits. The shoes are welded onto standard single-wall casings and help provide sound, easy to maintain and replaceable cutting edge to the casings.
The casing shoes help protect the casing body and at the same time lead to ease in installing the casing because cutting of the formation is done by the HBA60 or HC20 bits and thus less friction is imposed on the casing as it is rotated in place. Moreover, there is no welding of the bits onto the shoes; when the HBA60 or HC20 bits begin to wear off, the worn bits can be removed from the holders and replaced by new bits.
