Admin In modern machining, the winkelbohrspindel (angle drilling spindle) plays a vital role in enabling high-precision drilling operations where conventional drilling tools cannot reach. By allowing the spindle axis to be adjusted at various angles, manufacturers can perform complex hole machining with greater efficiency, accuracy, and productivity.
This detailed guide covers everything you need to know about winkelbohrspindeln—their types, applications, benefits, and technical specifications.
What is a Winkelbohrspindel?
A winkelbohrspindel is a specialized drilling spindle attachment designed to perform machining operations at defined angles.

- Suitable for simple drilling tasks and repair work.
2. CNC-Controlled Angle Drilling Spindles
- Integrated into CNC machining centers.
- Angles adjusted automatically via programming.
- Ensures repeatable accuracy in high-volume production.
3. High-Speed Winkelbohrspindeln
- Optimized for fine drilling operations in lightweight materials.
- Operate at higher RPM ranges.
- Common in aerospace and electronics manufacturing.
4. Heavy-Duty Angle Drilling Spindles
- Built with robust housing and bearings.
- Designed for hard materials like steel or titanium.
- Provide maximum torque and stability.
