The fixed diameter hole opener is made of tough heat-treated alloy
steel for maximum strength. The cutter arm is equipped with a
detachable cutter and is hard-faced welded on the valve body. There
are three types to choose from: SM type is used for soft to medium
formations, MH type is used for medium to hard formations, and XH
type is used for hard formations. The hole opener has three or six
nozzles, which can be replaced, so that the jet can quickly clean
the enlarged hole.
