Thread cutting taps are precision tools used to create internal threads in pre-drilled holes. They are widely used in CNC machining, automotive, machinery, aerospace, and general manufacturing.
What Are Thread Cutting Taps?
Unlike forming taps, thread cutting taps create threads by removing material and producing chips.
Common types include:
- Straight Flute Taps – General machining and short holes
- Spiral Flute Taps – Blind holes and continuous-chip materials
- Spiral Point Taps – Through holes and high-volume CNC production
- Pipe Taps – BSP, NPT, and other pipe threads
How Are Thread Cutting Taps Manufactured?
The main manufacturing steps include:
- Material Selection – HSS, HSS-Co, or PM-HSS according to the application.
- Blank Preparation – Producing the required tap dimensions.
- Heat Treatment – Achieving the required hardness and toughness.
- Flute Grinding – Creating accurate cutting geometry and chip evacuation.
- Thread Grinding – Controlling thread profile, pitch, diameter, and tolerance.
- Coating & Inspection – Improving wear resistance and verifying dimensional accuracy.
How to Choose the Right Tap
Consider:
- Workpiece material
- Through or blind hole
- Thread diameter and pitch
- Thread standard
- Tap material
- Production volume
- Cutting speed and lubrication
For example, spiral point taps are generally suitable for through holes, while spiral flute taps are commonly used for blind holes.
