Cargo Carbide 3PKT Indexable Cutter is a replaceable-insert CNC milling tool designed for efficient shoulder milling, face milling, step milling and general material-removal applications. The cutter uses 3PKT indexable inserts, allowing the cutting edge to be replaced without changing the complete cutter body.

3PKT tooling is commonly associated with 90° shoulder milling systems, making it suitable for machining square shoulders, side walls and steps while also supporting face-milling operations depending on the cutter design. Commercial 3PKT cutter systems are available in different diameters, shank configurations and insert capacities to suit different CNC and VMC applications.

The replaceable-insert construction gives manufacturers flexibility to select an appropriate insert grade and geometry for the workpiece material and machining operation. 3PKT systems are available for applications involving steel, stainless steel, cast iron and other engineering materials when the correct insert specification is selected.

Cargo Carbide 3PKT Indexable Cutters are suitable for workshops requiring a practical indexable milling solution for production machining, job work and general CNC milling.

3PKT Insert Compatibility

3PKT inserts are used across multiple indexable milling cutter configurations. Industry tooling references show 3PKT1004 and 3PKT1505 among the available insert designations, while different cutter bodies can be matched to different 3PKT sizes.

Always confirm the exact insert designation before ordering replacement inserts.

3PKT Indexable Cutter Applications

• 90° shoulder milling
• Square shoulder machining
• Face milling
• Step milling
• Side milling
• Pocket machining
• Edge milling
• General roughing
• Semi-finishing
• CNC component machining
• VMC production machining
• Die and mould components
• Automotive components
• General engineering parts
• Job-work machining

3PKT milling systems are specifically listed for shoulder milling, while some configurations are also marketed for face milling of larger flat surfaces.

Key Benefits

• Replaceable insert system – Change the cutting insert without replacing the complete cutter.
• 90° shoulder capability – Suitable for producing square shoulders and vertical side walls with compatible cutter designs.
• Face milling capability – Selected 3PKT cutter configurations can be used for face milling.
• Flexible cutter sizes – Different diameters and tooth configurations are available across the market.
• Insert grade flexibility – Select an insert according to material and machining conditions.
• Production friendly – Suitable for repetitive CNC and VMC machining.
• Reduced tooling replacement – The reusable cutter body can remain in service while inserts are replaced.
• Multiple machining operations – One cutter platform can support shoulder, step, side and face milling depending on its geometry.

Why Use a 3PKT Indexable Cutter?

A 3PKT Indexable Cutter is a practical choice when the machining operation requires 90° shoulder milling with replaceable cutting inserts. Instead of replacing an entire solid cutter after edge wear, the worn insert can be removed and replaced with a new compatible insert.

The 3PKT platform is available in both compact milling heads and larger face/shoulder milling configurations, giving manufacturers flexibility when selecting tooling for different component sizes.

3PKT Indexable Cutter vs Solid Carbide End Mill

3PKT Cutter for VMC

Cargo Carbide 3PKT Indexable Cutters can be selected for VMC machining where the cutter mounting arrangement and machine capacity are compatible.

Before selecting a cutter for a VMC, check:

• Cutter diameter
• Shank or arbor size
• Machine spindle interface
• Number of teeth
• Insert size
• Required cutting depth
• Workpiece material
• Spindle power
• Maximum spindle speed
• Workpiece rigidity

3PKT Cutter for Steel

For steel machining, select a suitable 3PKT insert grade and chipbreaker based on the steel grade, cutting depth, feed rate and required surface finish.

A rigid setup and correct insert selection are important for maintaining stable cutting during shoulder and face milling.

3PKT Cutter for Stainless Steel

When machining stainless steel, choose an insert geometry and grade intended for stainless-steel cutting conditions. Proper cutting parameters can help control heat and built-up edge while maintaining consistent tool performance.

3PKT Cutter for Cast Iron

3PKT milling systems can be configured for cast-iron machining with a suitable insert grade and cutting geometry. The insert should be selected according to the specific cast-iron material and machining condition.

3PKT 90 Degree Shoulder Milling Cutter

A major application of 3PKT tooling is 90° shoulder milling. A suitable cutter body and insert combination can produce shoulders, steps and vertical walls during CNC milling. Industry catalogs specifically list 3PKT cutters under 90° shoulder milling systems.

How to Select the Correct 3PKT Indexable Cutter

1. Select the cutter diameter according to the machining width and available machine power.
2. Confirm the 3PKT insert size required by the cutter body.
3. Check the mounting system such as shank or arbor.
4. Choose the number of teeth according to feed requirement and machine capability.
5. Select the insert grade according to the workpiece material.
6. Select the corner radius according to the required shoulder, surface finish and cutting depth.
7. Check coolant arrangement if through-coolant is required.
8. Set cutting parameters according to the selected insert manufacturer's recommendations.

Common 3PKT Cutter Configurations

Commercial 3PKT cutter listings show different configurations including straight-shank milling heads and larger face/shoulder milling bodies. Some examples are offered with multiple tooth counts and different cutter diameters.
