High precision & high speed
Body accuracy 0.002mm, dynamic balance G2.5 25000~30000RPM. Through the dynamic balance test, we pursue high-precision and high-speed tool balance, adapt to high-speed cutting processing, and extend the service life.
Small diameter design, deep hole processing
The small diameter design of the front end reduces interference and vibration, ensuring more stable high-speed machining and more stable deep cavity machining.
Built-in design, fast work
The built-in design simplifies the installation, eliminates the need for nuts, reduces accidental interference in the processing process, and is more suitable for high-speed processing.
Stable performance, more durable
The taper angle of the inner hole is designed to facilitate the loosening and holding force of the tool, and improve the stability.
Installation Instructions
This product needs to be matched with: 1. pull stud (used to connect with the main shaft of the machine) 2. collet (used to clamp the tool in the tool holder) 3. Milling cutter (clamp and fix with collet)
For more installation steps, please refer to the example in picture ① ② ③ ④ for clamping and disassembling.
Product packaging
There are many models and specifications, and the display is limited. Different types of products have different packaging, which can be used as packaging reference. If the quantity you need is large, we can design the package you need according to your requirements.
