NEW MANUFACTURE / REPAIR / REDRESS
Fishing and Milling Tools
NTECH manufactures, repairs and redresses downhole tools for the Turkish oil and gas industry. The portfolio covers milling obstructions, recovering magnetic debris and inspecting the top of a fish before recovery.
Restore Wellbore Access
Our workshop combines precision machining with downhole tooling expertise. Tool selection and cutting profiles are matched to the application. Tungsten carbide, blade geometry, gauge protection and debris clearance support cutting performance and circulation at the working face.
Frezeleme takımlarında tungsten karbür kullanılır. Kesici kenarların konumu, kanat geometrisi, dış çapın korunması ve talaş tahliyesi, kesme performansını destekleyecek ve çalışma yüzeylerinde dolaşımı koruyacak şekilde tasarlanır.
General and Heavy-Duty Milling
Bladed Junk Mill
Bladed Junk Mills are dressed with high quality tungsten carbide to support effective cutting and wear resistance. Bladed Junk Mills are suitable for all types of general junk milling, as well as the removal of packers, retainers and squeeze tools.
- Tool OD:
- 3½–28 in
- Fishing neck:
- 2⅞–11¼ in
Cone Buster Mill
Cone buster Mills are ideal for heavy milling such as bit cones, slips and pieces of downhole tools. A concave cutting face with a thick cutting structure supports wear resistance and efficient milling. This type of mill is not recommended for cement cleanout.
- Tool OD:
- 3½–17½ in
- Fishing neck:
- 3⅛–9½ in
Cleanout and Insert Milling
Cement Mill
Cement Mills are designed for light milling applications, including float collars, plugs, bridge plugs and retainers. An open cutting pattern helps clear cement and formation material, reducing clogging during cleanout. Tungsten carbide dressing supports milling where steel components may also be encountered.
- Tool OD:
- 3½–17½ in
- Fishing neck:
- 2⅞–9½ in
Carbide Insert Mill
Carbide Insert Mills combine precision-positioned tungsten carbide cutting inserts with crushed carbide dressing for efficient downhole metal removal. Inserts on the leading blade faces provide defined cutting edges, while carbide dressing on the bottom faces supports milling performance and wear resistance. These mills are suited to milling fixed or cemented tubulars, packers, bridge plugs, retainers and other securely held downhole obstructions.

Tubular Milling Tools
Conductor Taper Mill
Conductor Taper Mills are used to clean out restrictions in platform or jack up conductor casings. Their design is similar to a normal taper mill but with a box connection down. This connection is useful for installing a smaller diameter taper mill, a junk mill or other pilot assembly. Conductor Taper Mills can ream out considerable deformation in one pass. Their heavy tungsten carbide dressing supports wear resistance and effective cutting.
- Tool OD:
- 15–28 in
- Fishing neck:
- 9½ in
String Taper Mill Pilot Mill Bladed Junk M
String Taper Mills are ideal for cleaning out damaged casing, liners or tubing, and are also recommended for removing key seats in open hole. The design tapers from the top and the bottom of the mill, allowing reaming operations from both directions. Pin down and box up connections allow the mill to be run in a drill collar string or combined with a smaller pilot assembly to avoid side-tracking when removing obstructions in casing.
- Tool OD:
- 3½–17½ in
- Fishing neck:
- 3⅛–9½ in
Guided Tubular Milling
Taper Mill
Taper Mills are designed specifically for milling through tight spots in tubulars. Heavy crushed carbide dressing increases on-bottom time, while ground OD and stabilizer pads help guide the tool and protect the casing. Taper Mills are recommended for cleaning out liners, tubing and other collapsed or deformed tubulars. They can also be run ahead of other milling tools to clean out “bird nests.”
- Tool OD:
- 3½–17½ in
- Fishing neck:
- 3⅛–9½ in
Pilot Mill
Pilot Mills are suitable for milling sections of tubular junk and can be used as a dress mill for the installation of a casing patch. They can be used for milling liner hangers and other downhole tools with a through bore.
- Tool OD:
- 3¼–17 in
- Fishing neck:
- 3⅛–8 in
Recovery and Diagnosis
Junk Magnet
Junk Magnets are used to retrieve small, oddly shaped debris with magnetic properties. Junk Magnets are frequently run in advance of diamond tools to remove debris that could adversely affect the tool’s performance. The Junk Magnet is constructed so that the internal pole plate is highly magnetized, but the rest of the tool remains non-magnetic. Junk Magnets are available in most hole sizes.

Impression Block
Impression Blocks are used to determine the position and condition of the top of a fish or junk in a well. Impression blocks feature a steel body with the lower end fitted with a block of soft material, typically lead. The tool is made up on the running string and lowered without rotation to make contact with the obstruction, leaving an impression that can be identified at surface. From this information, the appropriate fishing equipment can be deployed.

Manufacture, Repair and Redress
Extending the service life of appropriate tools reduces unnecessary tool changes and material waste.
- Situation assessment The tool body and the wear pattern are examined to determine suitability for repair.
- Profile renewal The profile of the usable bodies is corrected, and worn cutting surfaces are reconstructed to suit the specific application.
- Application control The tool configuration, connection type, dimensions, and cutting arrangement are verified according to the task to be performed.
When requesting a quote or technical information, you may provide details regarding well and pipe dimensions, the nature of any constriction or debris left in the well, the connection type, and the operating conditions.
Dimension ranges are provided for informational purposes. Before placing an order, please confirm the exact dimensions, connection type, availability, and suitability for your application with NTECH. The images are not to scale.
