CustomCut Pilot Mill
Lower-Connection Type
Weatherford's CustomCut lower-connection type pilot mill can be used to mill a
full range of tubular products. This versatile tool is run above a taper mill; but an
optional stabilizer can also be run with the taper mill as the pilot, which is sized
for the ID of the tubular. In addition, drill collars can be run below the mill for
milling weight in shallow-well applications. The major diameter section of the
lower-connection type pilot mill is sized at least 1/4 in. larger than the coupling
OD, eliminating creation of junk in the wellbore and extending the life of the pilot
mill. The CustomCut lower-connection type pilot mill is dressed with one of the
family of CustomCut inserts, as appropriate for the application.
Weatherford's lower-connection type CustomCut pilot mill is a product of the
company's MillSmartSM technology—an engineered approach to milling that
encompasses a wide range of proven products, services, and technical
resources, developed and refined by the world's largest and most experienced
provider of milling and fishing services.
Applications
— The CustomCut lower-connection type pilot mill is used for milling tubing,
casing, liner hangers, liners, drillpipe, drill collars, wash pipe, or perforated
liners.
— CustomCut inserts are specifically tailored to the operation and to the
capabilities of the surface equipment. For surface equipment or fluids with
limited capabilities, CustomCut 100 series inserts produce small, lightweight
cuttings. For premium fluids and high-volume surface equipment, CustomCut
200 and 300 series inserts maximize milling rates and the life of the pilot mill.

CustomCut Pilot Mill
Lower-Connection Type
Features, Advantages and Benefits
— Full OD ensures that collars are milled in the same operation, eliminating creation of junk in the wellbore
and extending the life of the pilot mill.
— Optimized alignment of CustomCut insert to proper cutting angle produces smaller cuttings for better
wellbore cleaning and longer life of the mill.
— Longer blades extend downhole cutting time and the life of the mill.
— Pin-down design facilitates the optimal, operation-specific bottomhole assembly to increase pilot milling
success.
— Insert selection capability optimizes the mill design to the composition of the tubular being milled and
the capabilities of surface facilities, resulting in higher rates of penetration.
