Sim-Cas 44

Available Shanks: Mach 44, A35-15 (SD4), IR DHD 340

The Sim-Cas 44 Shoedrive system is designed to be used with either threaded or welded casing, with a recommended outside diameter of 5 5/8" and an inside diameter of 5". When in operation the eccentric bit extends to produce a bore size of 6 1/8", reducing to 4 1/2" when it is retracted.

The casing drive shoe is available with either a spigot-type connection or a face butting-type connection. The internal diameter of the casing drive shoe is 4.63". This enables a button bit with a diameter of 4.59" (or less) to be used to drill through the casing if required.

An optional stabilizer is available.
