DKI's Wing King casing advancement system drives casing through loose overburden and down into solid bedrock in a single pass β a simple, robust 2 & 3 wing design built for durability and fast drilling speeds in any ground condition.

Wing King is Drill King’s newest casing advance system to market, designed around a simple cam-sliding mechanism: as drilling begins, the wings extend outward to cut a hole larger than the casing OD, allowing the casing to follow the bit down through loose, collapsing ground and seat securely once bedrock is reached.
The system is easily paired with Drill King’s full range of DTH hammers and is built to suit industry-standard casing pipe, including thicker-wall variants. Replaceable wings and key wear components keep running costs low, while a simple, low-cost plain steel casing drive shoe keeps cost-per-drilled-foot competitive against more complex casing systems.
A proven, low-complexity mechanism that's easy to maintain and quick to turn around in the field.
Covers casing OD from 4.5" (115mm) right up to 36" (914mm), the largest range of any Drill King casing advance system.
Wear parts are designed for fast field replacement, minimizing downtime between runs.
An inexpensive plain-steel casing drive shoe keeps overall tooling cost down without sacrificing performance.
Compatible with standard and thicker-wall casing pipe, with no special casing required.
Configure for casing left in the hole or pulled out after drilling, depending on your project's engineering needs.

Wing King covers casing OD from 4.5″ (115mm) up to 36″ (914mm), the widest range in Drill King’s casing advance line.
Yes. The system is built to suit industry-standard casing pipe, including thicker-wall variants, with no special casing required.
Wing King uses cam-actuated wings and covers a larger size range, making it well suited to large-diameter piling and bigger overburden jobs. Ring Bit uses a locking pilot bit design and is typically chosen for smaller, more precise casing applications. See our Casing Advance Systems hub page for a full comparison.
Yes, Wing King is available in both permanent (left-in-hole) and retrieved (pulled-out) configurations.
