Foremost Casing Shoe 

The Casing Shoe (also known as a Ring Bit) is a carbide-studded shoe, welded onto the lead piece of casing, thus converts your casing into a drill string. The ring style shoe cuts through boulders and hard formations as the casing rotates. This shoe (a.k.a. ring bit) enables the Dual Rotary drill to seat casing into bedrock. It is important to note that common casing shoes used with the DR system are designed to have the same inside diameter as the casing I.D. Consequently, there is no reduction in the borehole diameter when switching to open hole drilling. The outside diameter of the ring bit is typically 5/8 inch larger than the casing O.D. for reduced friction on the outer wall of the casing.

If you are in need of a custom Casing Shoe or Ring Bit size, contact us today.  Foremost has the ability to custom build a casing shoe/ring bit to your preffered specification.
