One Piece Drill Bits For Well Completion And Workover

Some operators prefer to use one piece bits rather than roller cones. The Chomp, Bear Claw, Hurricane and Aardvark well completion mill bits are an excellent choice because they guarantee no lost rig time fishing for cones.

Heavy duty design combined with over 50 years of experience of drill bit tooling and manufacturing ensures a high success rate. As a matter of fact, the current success rate is 99.09%.

Each well completion drill bit is specifically designed for a particular purpose: drilling cement, milling cast iron or other metals, high pressure multiple plugs and cemented pipe, milling composite plugs and other extremely hard and abrasive materials.

Chomp Well Completion Milling Bit
Full Body Chomp Mills are ideal in applications that involve milling of cast iron and other metal or combination of cement and cast iron.

Large ports for reverse circulation.

Recommended WOB 4000 - 6000
(can be adjusted as needed)
RPM 80-100 rotary, 400 - motor
Bear Claw Well Completion Milling Bit
Full Body Bear Claw Mills are ideal for drilling cement. Not recommended for drilling metal.

Large ports for reverse circulation.

Recommended WOB 4000 - 6000
(can be adjusted as needed)
RPM 80-100 rotary, 400 - motor
Hurricane Well Completion Milling Bit
FBC1S Hurricane Mills are recommended for milling cement and composite plugs.

The FBC1S Hurricane has domed inserts on the outer diameter for increased durability and chisel inserts in the inner rows for faster penetration.
Hurricane Well Completion Milling Bit
For applications involving the drilling of metal, the FBCS Hurricane Mill has all domed inserts and is recommended for use in applications that involve milling composite and cast iron plugs, other metal and cement. The FBCS is suitable for a wider range of applications.

Both the FBC1S and FBCS Hurricane mills incorporate a spiral design with channels for improved cleaning and circulation.

Recommended WOB 4000 - 6000
(can be adjusted as needed)
RPM 80-100 rotary, 400 - motor
Aardvark Well Completion Milling Bit
Aardvark full body tapered mill is recommended for milling high pressure composite plugs. It can also be used for cement and cast iron milling. The Aardvark's unique design can rapidly mill multiple
(from 1 to 20) composite plugs.

Recommended WOB 6000 - 8000
(can be adjusted as needed)
RPM 80-100 rotary, 400 - motor
PDC Well Completion Milling Bit
PDC Mills are used for milling extremely hard and abrasive materials. Uses range from milling hard cement and sand to milling hard scales, such as barium scale. Not to be used when any metal will be encountered.

Hurricane style PDC Mills are available in limited sizes.

PDC Mills offer the ability to mill very hard cement and scales without changing mills.

PDC inserts for extended wear and abrasion resistance.

Full body design (no fishing for lost cones).

CNC machined bodies and threads for accuracy.

Bodies manufactured from 4140 HT steel.

Sizes available from 1 3/4 inch to 8 3/4 inch in 1/8 inch increments.

Circulation ports from 5/16 inch to 1 1/8 inch.

The above mills are all CNC machined for accuracy, and all bodies are manufactured from 4140 HT steel. Various threads are available for customer's needs:
1 in. MT DSI
1 1/4 in. MT DSI
1 1/2 in. MT DSI
2 3/8 in. API REG
2 7/8 in. API REG
3 1/2 in. API REG
4 1/2 in. API REG
2 3/8 in. PAC
Twister Well Completion Milling Bit
The Twister is an economical, well workover bit that is great for milling cement, composite plugs, cast iron plugs and other difficult to drill applications.

*Precision machined 4140 heat treated steel

*Equipped with break out flats

*Forced balance cutter layout to drill a precise, round hole

*High speed motor applications or lower RPM standard circulation applications

*Gage pads have 10 tungsten carbide inserts for increased wear resistance

*Lowest cost

*Available in three designs:

Model XYG has special modified chisel type inserts on outside rows to cut cast iron plug rings, and longer aggressive chisel inserts for composite material on well plugs.

Model XG has aggressive chisel inserts throughout allowing maximum ROP and aggressive cutting.

Model YG has special modified chisel type inserts

Available in 3 5/8, 3 3/4, 3 7/8, 4 5/8, 4 3/4, 4 7/8 and 6 1/4.
