The hammers are designed to provide increased reliability, enhanced performance and faster penetration rates than previous versions.

Numa president Ralph Leonard said: "The new generation of the Patriot 60 and Patriot 65 hammers was designed with direct feedback from drillers.

"Numa took drillers' input and created the new generation to deliver fast and reliable drilling in demanding applications around the globe."

The Patriot 60 hammer is suitable for water well, construction, oil & gas, utility, quarry and mining drilling applications, where contractors are not looking to run a heavy-duty version. The hammer features a reversible case and operates at a higher pressure than the previous generation.

Tests have proven the hammer has a higher BPM (blows per minute) and drills consistently against back pressures, like water in the hole, Numa said. The Patriot 60 has a 5.5in (139mm) outside diameter and runs QL60 shank bits capable of drilling holes 6in to 8¾in (152mm to 222mm) in diameter. A version of the Patriot 60 is also available for 360 shank bits.

The Patriot 65 is a heavy-duty hammer designed specifically for the quarry, mining and construction industries where ground conditions warrant. The hammer boasts a thicker, reversible case but also produces the highest BPM of all Numa hammers. The Patriot 65 comes standard with back-out carbides on the topside of the backhead to aid in recovery in the event of hole collapses. An additional option is carbide weld chucks for improved wear in highly abrasive formations. The Patriot 65 has a 5.75in (146mm) outside diameter and runs QL60 shank bits capable of drilling hole 6¼in to 8¾in (159mm to 222mm) in diameter.
