3 Point Reamers

3pt Reamer

Rock - Solid Reamers

Cougar reamers are manufactured to give long service even under the most severe reaming conditions. Milled, onepiece bodies, in 3 - point or 6 - point configurations, provide enormous strength while allowing maximum fluid flow around the reamer in both bottomhole and string applications. A variety of cutters are available for every formation type, be it chert, sandstone, or shale.

Reamer Performance

Increased durability

Cougar roller reamers are manufactured to give long service even under the most server reaming conditions. Cutters, bearing blocks and cutter pins are made from molybdenum alloy steel, carburized and quenched to 58-62 Rockwell C. Cutter pins may be rotated 180 degrees for prolonged use.

Faster redress

Changing cutters is simple: Drive out one spring-pin and the cutter pin, then replace them. A punch, drive bar and hammer are the only tools you’ll need.

Greater versatility

Cougar roller reamers are available in 3-point or 6-point configurations for bottom hole or string applications. The 6-point bodies, for use in severely crooked holes, will minimize dog legs and optimize hole configuration
