Cargo Carbide 3PKT Facemill Cutter is an indexable CNC milling cutter designed for efficient face milling, shoulder milling and general material-removal operations. It uses replaceable 3PKT inserts, allowing worn cutting edges to be changed while retaining the cutter body.

3PKT face-milling systems are commonly designed around a 90° cutting configuration, making them suitable for producing flat surfaces as well as machining shoulders, steps and edges. Commercial 3PKT face mills are available in different diameters, tooth counts and insert sizes to match different machining requirements.

The 3PKT insert family is also available in different geometries and grades for applications such as facing, shouldering, slotting and ramping. This allows the cutter system to be configured according to workpiece material and machining conditions.

Cargo Carbide 3PKT Facemill Cutters are suitable for CNC and VMC workshops looking for a reusable indexable cutter body with replaceable milling inserts.

Product Specifications

3PKT Facemill Cutter Sizes

3PKT face mills are manufactured in different diameters and tooth configurations. Public tooling catalogs show examples ranging from compact face mills to larger cutters. For example, one 3PKT1505 face-mill series is listed in 50, 63 and 80 mm diameters with different tooth counts.

3PKT1004 vs 3PKT1505

Different 3PKT insert platforms are associated with different cutter bodies, so the insert must always match the cutter pocket.

Applications

• CNC face milling
• VMC face milling
• Flat surface machining
• 90° face milling
• Shoulder milling
• Step milling
• Side machining
• Edge milling
• General roughing
• Semi-finishing
• Component machining
• Automotive component manufacturing
• General engineering
• Die and mould components
• Job-work machining
• Batch production

Key Benefits

• Replaceable insert design – Replace the cutting insert instead of the complete cutter.
• 90° face-milling capability – Suitable for flat surfaces and compatible shoulder applications.
• Reusable cutter body – The cutter body can remain in service while worn inserts are replaced.
• Multiple insert options – Select grades and geometries according to material and operation.
• CNC/VMC compatibility – Suitable for common CNC milling environments when the mounting system matches.
• Production flexibility – Different cutter diameters and tooth configurations can be selected.
• Multi-purpose machining – Depending on cutter and insert geometry, the system can perform facing, shouldering, slotting and ramping.

Why Use a 3PKT Facemill Cutter?

A 3PKT Facemill Cutter is useful when a machining process requires efficient surface milling with replaceable inserts. Instead of replacing an entire solid milling tool after cutting-edge wear, the operator can replace the compatible insert and continue using the cutter body.

The 3PKT platform is particularly useful for machining operations involving facing and 90° shoulder work, with insert configurations available for different machining conditions.

3PKT Facemill Cutter vs Solid Carbide End Mill

3PKT Facemill for VMC

A 3PKT Facemill Cutter can be used on a VMC when the cutter mounting arrangement is compatible with the machine spindle and arbor.

Before using the cutter, verify:

• Cutter mounting / arbor
• Cutter diameter
• Bore size
• Number of teeth
• Insert designation
• Spindle power
• Maximum spindle speed
• Required cutting depth
• Workpiece rigidity
• Coolant requirements

3PKT Facemill for Steel

For steel machining, select a 3PKT insert grade and chipbreaker suitable for the specific steel grade and cutting conditions.

The correct insert geometry should be selected according to the required cutting depth, feed, surface finish and material hardness.

3PKT Facemill for Stainless Steel

When machining stainless steel, select an insert geometry and grade intended for stainless-steel applications. Proper cutting parameters and a rigid setup are important for controlling heat and built-up edge.

3PKT Facemill for Cast Iron

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

90° 3PKT Face Mill

The 90° configuration is an important feature of many 3PKT face-milling systems. It allows the cutter to perform facing while also supporting square-shoulder machining when the insert and cutter geometry are designed for that operation.

How to Select the Correct 3PKT Facemill Cutter

1. Select cutter diameter according to the surface width and machine capacity.
2. Confirm the 3PKT insert size required by the cutter.
3. Check bore or arbor mounting to match the machine.
4. Select number of teeth according to feed requirements and spindle power.
5. Choose insert grade according to the workpiece material.
6. Check corner radius according to the required surface finish and machining depth.
7. Confirm maximum cutting depth for the selected insert and cutter.
8. Set cutting parameters according to the insert manufacturer's recommended data.

Common 3PKT Facemill Configurations

Industry catalogs show 3PKT face-milling bodies in multiple diameter and tooth configurations. One catalog lists 3PKT1505 face mills at 50, 63 and 80 mm, while another lists 3PKT1505 face mills up to 125 mm and 3PKT1906 configurations in larger diameters.
