Tungsten carbide plates provide effective cutting at high rate of penetration

Mills

Junk Mills

Junk mill FZ2 — is effective tools for milling metal objects on the bottomhole. Cutting surface is reinforced with composite material made up of granulated hard alloy and binder material that allows mill to easily operate in difficult milling conditions where high durability of tool is required.

Concave junk mill FZV2 — is modification of FZ2 with concave working surface that allows centralizing unfixed milling objects relative to mill.

FZ2  FZV2 mills can be produced with increased cover of granulated hard alloy that is designated by «Y» letter in the end of tool series name.

Special junk mill FZ2 Sp — is the most effective and multi-purpose tool for drilling out cement and sand plugs, casing equipment, milling metal objects on the bottomhole.

Effective cutting at high ROP is achieved due to tungsten carbide plates and self-sharpening effect.

Combined cutting structure considerably increases mill operating characteristics and expands area of application: besides milling light alloy pipes, tubings, drilling out cement plugs at favorable conditions FZ2 Sp successfully recommended itself in milling casing equipment and drill pipes.

Spiral junk mill FZS2 is designed for drilling out cement and sand plugs, casing equipment, milling metal objects on the bottomhole.

Special feature of this tool is cutting face and spiral gauging blades reinforced with granulated hard alloy.

Washover Mills

Washover mill FK2 has massive cutting edge reinforced with granulated hard alloy and designed for milling big metal objects in heavy conditions.

Washover mill FK2 Sp is reinforced with granulated hard alloy and tungsten carbide teeth. Designed for milling stuck drill pipes, tubings and sucker rods.

All washover mills are produced with welding bevel.

Combined Mills

Washover junk mill FZK2 is combination of junk and washover mills. Designed for continuous milling pipes, unfixed metal objects with outrunning milling of annular space in cased well.

Washover junk mill FZK2 Sp is combination of washover and special junk mills. Effective cutting at high ROP is achieved due to tungsten carbide plates and self-sharpening effect.

Pilot mill FP is designed for milling components of tubings, liners, packers, joints and sleeves during repair-and-renewal operations.

Capable to work in heavy milling conditions where high durability of tool is required. Main design feature is cutting surface reinforced with composite material made up of granulated hard alloy and binding material.

Magnetic mill FM is multi-porpose tool designed for retrieving metal objects with ferromagnetic properties from well. Cutting mill crown allows milling metal object before retrieving.

Taper String Mills

Taper string mills are designed for reaming elliptical pipes (restoring internal diameter), milling out a collapsed section of pipes, removing an internal surface roughness and cleaning a casing window.

Main feature of this tool is a tapered working surface reinforced with granulated hard alloy. Taper string mill FKK2 has cone angle of 10° and taper reamer mill RK2 — 5°.

At customer option all mills of FKK2 and RK2 types can be produced with central flushing hole, thus marking will include index «C».

Reamer Mill and Bit-mill

Reamer mill FR is designed for drilling-out cement and sand plugs, casing equipment and milling metal objects on the bottomhole. Effective cutting at high ROP is achieved due to tungsten carbide plates and self-sharpening effect.

Bit-mill DtF is designed for drilling-out cement and sand plugs, casing equipment in favorable conditions with small impact loads.
