Thread Milling:

• Chip producing method
• Thread making by helical interpolation within the pitch
• Same tool can be used for all threads with the same pitch starting from the nominal Ø
• Same tool can be used for different materials up to 45 HRC
• Lower torque than with tapping and roll form tapping
• Drill depth = thread depth if tool is not used for chamfering
• Machine spindle always running in the same direction – no reversing necessary
• High speed cutting (HSC) possible

Drill Thread Milling:

• Chip producing method
• Complete thread is manufactured in a single pass – drilling, chamfering and thread milling
• One tool per dimension which can also be used for different materials
• Prerequisite: CNC machine or machining centre being capable to run helical interpolation
