The AS5202 Minor Diameter Port Kit is a precision-matched set for controlled port creation, particularly when drilling the minor diameter and finishing with a pilotless port tool. It includes:

• DFX Drill – Cuts the minor diameter to spec

• AS5202 X-Series Port Tool – Pilotless design for clean, controlled finishing

• 15° Helical Thread Mill – Produces accurate threads with excellent finish quality

This kit is perfect for shops that prefer to separate roughing and finishing steps, or for applications requiring specific depth control. All tools are optimized for machining from solid or semi-prepped stock while maintaining AS5202 porting standards.
