The Mills Machine Overshot is a rugged, external catch, fishing tool that is economical and simple to use. Overshots are manufactured like taper taps except they go over the O.D. of the fish. Like taper taps, overshots are stocked in a variety of sizes and standard connections so we are able to get something to you rapidly. To build an overshot from scratch takes four to six days due to the heat treat process necessary to harden the teeth. It is speedier to build a sub to fit a stocked overshot and match your needs than to build the entire product. We can build the overshot with oversize guides to more easily catch the fish or with a wall hook to snag behind a fish leaning against the drill hole wall. Your Mills sales representative will work with you to get the fastest solution to your problem at the lowest cost. The carbonized threads on overshots are extremely hard and brittle. Be extra careful to avoid impact. In use, slowly lower the tool down the hole until the fish is engaged. Then slowly rotate the tool while applying some down pressure. Mark the drill rod to tell how far into the fish you have penetrated. Overshots can be reworked by annealing, re-threading the overshot and then re-heat treating the re-threaded area. We will quote you pricing as necessary.

This drilling tool is an Over shot fishing tool. To construct this part it we manufacture in a similar fashion to the fishing spear. The over shot is precision CNC machined from hardened high alloy steel. And has a sharp internal thread profile. This fishing tool latches to the outside diameter of the broken down hole drilling tool. The hard sharpened threads are designed to latch and thread into the part.

Fishing tool is a special fishing drilling tool used to retrieve fallen objects from the borehole. At any stage of the operation, the drill rig operator will encounter unexpected situations, such as falling drill string, stuck pipe, missing drill bit, etc. The equipment that falls into the well is called "fish" or "trash", and the tools used to remove the equipment are called "fishing tools." Sometimes it may be necessary to use "fishing tools" to retrieve older wellbore equipment, such as packers, liners, tubing, or any stuck objects in the well. The drilling tools for fishing must be retrieved from the borehole in order to continue drilling operations.

Overshot is a very common fishing tool. The main fishing object is a smooth tube fish, which belongs to the external fishing type (i.e. catching the external surface of the fish).

Taper tap and die collar are common fishing tools for fishing the inner hole of the string. They are used for fishing the inner hole with holes such as tubing, drill pipe, casing milling pipe, packer, water distributor, etc. It is made of high-quality alloy steel and especially heats treated. It has the advantages of high strength, high toughness, and simple buckle making.

The Series 10 Sucker Rod Overshot is a small, rugged tool designed for engaging and retrieving sucker rods, couplings, and other items from inside tubing strings.

Series 20 Short Catch Sucker Rod Overshots are designed for conditions when sucker rods, couplings, and other portions of a fish are too short for retrieval with a standard overshot.

The Hydraulic Release Overshot was designed to aid in the recovery of a stuck fish in a horizontal drilling application where normal rotation for release is not obtainable.

The Series 150 Releasing and Circulating Overshot consists of three main external parts: a Top Sub, a Bowl, and a Guide. Internal catch and pack-off parts are determined by the diameter of the fish. Each assembly is designed for a maximum catch diameter.

A Series 160 Side Door Overshot is recommended when fishing for cable tools or conductor lines in cased holes. The side door overshot is run in on tubing or drill pipe.

A Lead Impression Block is an effective tool used to determine dimensions, configuration, condition, and location of the top end of a fish in the hole.

Rotary Die Collars are the simplest external catch fishing tools designed for retrieving a fish from the hole. Die Collars are available in two types: Type A and Type B.

Releasing Spears provide a positive means to engage and retrieve an internal fish from the well. The design of this rugged, dependable, and inexpensive internal catch fishing tool ensures positive engagement, easy release and re-engagement. It may be used with other equipment such as pack-off assemblies and internal cutters.

The Packer Retriever Spear is designed to remove drillable full-bore packers from the well casing. With appropriate dressing, the tool can mill through the packer if necessary.

The Core Type Junk Basket is an easy to use junk retrieval tool designed to effectively remove small objects such as bit cones, slips, hand tools, and tail chains from the hole.

The Fishing Magnet is designed to retrieve small metal, oddly shaped objects such as mill shavings, bit cones, cutters, bearings, slips, tong pins and hand tools for the bottom of the well bore.

The Magna Fish™ Fishing Magnet is designed to retrieve small metal, oddly–shaped objects such as milling shavings, bit cones, cuers, bearings, slips, long pins, and hand tools from the boom of the wellbore. Typically, these objects are the result of bit failures, and accumula!on of mill cuttings, or simply accidental droppings of unmillable objects.

The Superior Hydraulic Jar is a straight pull, up only, jarring tool that utilizes a special valve section to meter oil from one side of the piston to the other side. This allows for controlled jarring action during stuck fish recovery.

The Superior Energizer is run in conjunction with a Superior Fishing Jar of the same size. Its function is to supply intensified impact during the jarring operation. Each size of Superior Energizer is designed to match a corresponding size of Superior Fishing Jar.

The Z Type Hydraulic Jar is used for light drilling, fishing, coring, reaming, testing, side tracking, and washover operations. This straight-pull jar combines the principles of mechanics and hydraulics in a simple to assemble, easy to operate design.

The Z Type Energizer is run in conjunction with a Z Type Fishing Jar of the same size. Its function is to supply intensified impact during the jarring operation. Each size of Z Type Energizer is designed to match a corresponding size of Z Type Fishing Jar.

The Surface Bumper Jar is installed in the drill string at the surface and is used whenever the downhole drilling, fishing, or washover running string becomes stuck and requires a heavy downward force to release it.

The Lubricated Fishing Bumper Sub is a dependable accessory that is suitable for all fishing operations, especially harsh, downhole applications and deep workover operations.

One of the most common tools used for any kind of fishing job is the bumper sub. The tool’s design allows full torque and unrestricted fluid circulation at all times.

The Jar Tester is a versatile machine for setting, checking, or testing pull loads of a variety of tools with outer diameters up to 11 inches. The Jar Tester is capable of exerting tension or compression loads in a controlled manner.

The Drill Pipe Safety Joint is designed for the safe and dependable release from drilling, fishing, tubing, washover, or testing strings should they become stuck.

The Tubing Safety Joint is designed for the safe and dependable release from drilling, fishing, tubing, washover, or testing strings should they become stuck.

The Washover Safety Joint is designed for the safe and dependable release from drilling, fishing, tubing, washover, or testing strings should they become stuck.

The Type J Safety Joint provides a release option from tools such as taper taps or die collars that are normally non-releasable. It also provides a way to connect or disconnect fishing string and stuck fish.

The Bi-Directional Coiled Tubing Jar is designed to hit upward and downward blows. It can be dressed to only hit up or down. These tools’ small outside diameters and shorter lengths make them ideal for milling, drilling, workover, remedial, or completion operations, especially in vertical, deviated, and ultradeep wellbores.

The double-acting, Bi-Directional Coiled Tubing Energizer is an impact enhancement tool designed for slim holes (generally a well bore less than 6 inches in diameter). Its function is to supply intensified impact during the jarring operation by providing or enhancing jar impact from energy stored within its oil-filled compression chambers.

Junk Mills are hard-faced with sintered tungsten carbide particles that mill away stuck fish that can not be retrieved with conventional fishing methods. These tools are highly resistant to impact and their super rates of penetration result in fewer round trips. Their maximum useful life is enhanced by their self-sharpening feature.

The Welded Cup Junk Sub is an accessory tool that prevents cuttings from milling or drilling operations that are too heavy to be circulated from settling at the bottom of the hole.

The Threaded Cup Junk Sub is an accessory tool that prevents cuttings from milling or drilling operations that are too heavy to be circulated from settling at the bottom of the hole.

The automatic spring-fed knives feature of this tool prevents excessive strain from being applied from the rig floor that could cause the knives to burn or break before the cut is completed.

These quick, smooth operating tools allow for fast recovery of tubing or drill pipe. A hydraulically fed piston forces the knives of this cutter into the pipe to give the operator sensitive cutting control.

The Hydraulic Rod Jar provides a dependable means for controlled jarring in sucker rod operations when electrical continuity or circulation to the tools or below the jar is not required.
