Drill King's casing shoes and casing crown bits are built to guide and protect rotary casing as it advances through unstable, unconsolidated, or variable overburden — giving drillers a reliable way to case and drill simultaneously without losing hole integrity, built to the same standard water well, geotechnical, and mining teams have relied on for decades of casing advance work.

Casing advance drilling exists for one reason: keeping the hole open in ground that won’t hold itself. Since rotary casing systems were adopted to meet that exact demand, casing shoes and crown bits have continually evolved to cut cleaner, wear longer, and hold gauge through more difficult formations — and Drill King’s casing shoe and crown bit range is built to that standard.
Manufactured to suit a variety of rotary casing sizes, Drill King’s casing shoes and casing crown bits give water well, geotechnical, construction, and exploration drillers a dependable way to advance casing through overburden, running sand, gravel, and other difficult ground — with popular production and stock sizes ready to ship, and custom configurations available on request for projects that fall outside the standard range.
Popular production and stock sizes covering 133mm–234mm diameters, sized to match standard rotary casing strings.
Available with double lead or triple lead threads, right hand or left hand, to match your casing string and rig configuration.
Premium or standard carbide in parabolic, dome, or chisel profiles, selected to suit the formation and cutting action required.
Wear pads available for extra protection against abrasive ground, extending shoe and bit life across longer casing runs.
Additional heat treatment available where project conditions call for extra hardness and durability.
Manufactured in Mansfield, Texas, to Drill King's ISO 9001:2015 quality standard, certified since September 2017.

Both fit to the leading edge of a rotary casing string to guide it through the formation. Casing shoes are typically the cutting reference for the casing pipe itself, while casing crown bits describe a carbide-faced cutting profile on that leading edge — Drill King builds both to suit different casing systems and formation conditions.
Popular production and stock sizes include 133mm x 140mm, 152mm x 160mm, 152mm x 154mm, and 219mm x 234mm, matched to standard rotary casing.
Yes. Alongside the popular stock sizes, our technical team can discuss custom sizing to match casing strings outside the standard range.
Double lead or triple lead threads in right hand or left hand configurations, paired with premium or standard carbide in parabolic, dome, or chisel profiles.
Not by default, but additional heat treatment is available on request for projects running in especially abrasive or demanding ground conditions.
