Port Mills

SCT Port Mills machine SAE J1926 ORB and AS5202 hydraulic port profiles using circular or helical interpolation from a pre-drilled hole. Available uncoated or with Versa (AlCrN).

Port Mill vs. Port Contour Cutters 

One Port Mill can cover a range of port sizes, reducing the need to stock a dedicated porting tool for every individual size.

Manufactured by Scientific Cutting Tools
 
 

AS5202

  • Machines AS5202 port profiles using circular interpolation

  • Generates the seal surface, counterbore, and chamfers

  • Improves access in tight spaces and restricted setups

  • Covers multiple port sizes with one tool

  • Available uncoated or with Versa (AlCrN) coating

AS5202 Port Mills are solid carbide milling tools designed to generate AS5202 hydraulic port profiles through circular interpolation from a pre-drilled hole. Each tool covers a range of port sizes, making the series a flexible option for prototypes, small batches, and applications that are difficult to reach with traditional porting tools.

Product Comparison: Port Mills vs. Traditional Porting Tools

Traditional porting tools are an effective choice for many dedicated production applications. 

Port Mills add flexibility when the job calls for more access, smaller machine compatibility, or broader size coverage.

  • Hard-to reach port locations
  • Angled faces or tight spaces
  • Smaller or lower-RPM equipment
  • Prototypes, repairs, and small batches

Versa (AlCrN) Coating

  • Best for: Steels, stainless steels, tool steels, titanium, high-temp alloys, cast iron
  • Choose it when: Heat and wear are the primary challenges.
  • Helps with: Heat resistance, wear protection, and stable cutting performance
