Numa launched a range of casing ring bit systems for simultaneously drilling and casing vertical or horizontal holes in piling, foundation, anchoring, geothermal and other casing applications.

The range is a complementary product to Numa’s Super Jaws overburden bits and impact ring bit systems.

Numa’s casing ring bit system consists of a pilot bit, casing shoe and heavy-duty ring bit. It is available in a range of sizes for drilling holes 16 in. to 48 in. in diameter. The design is highly configurable, Numa says, with options for both drill-through and non-drill-through applications requiring the installation of casing into bedrock. The system also boasts the ability to handle overburden and hard rock conditions using either conventional or reverse circulation DTH (down-the-hole) hammers.

“We are pleased to announce the addition of Numa’s casing ring bit systems to our product line,” says Ralph Leonard, Numa president. “This advancement is yet another example of Numa’s rock-solid reputation for designing dependable drilling products that deliver in mission-critical, harsh applications.”
