User Reviews

JohnUSA
When the angle and rotation direction are both appropriate, the Big Brother cutting cutter produces a clean and crisp cut when cutting low-carbon steel brackets for automobiles, without tearing or burrs, making it much more efficient at handling small car fixtures.
JavierThailand
Big Brother's PCD end mills are polishable with excellent surface finish, offering not only high precision but also vibration resistance. The tool life is 2.5 times longer than our previous tools, and tool change time is reduced by 30%. Their tools are a fantastic solution tailored to our electric vehicle materials!
Li Wei China
Big Brother's carbide cutting tools have helped us overcome the significant challenges of machining high-hardness steels and aluminum alloys. These tools have a lifespan three times longer than our imported tools, and their R&D team has consistently supported our work, customizing tools specifically for our parts. They are a trusted partner for our company in the high-end automotive manufacturing sector!

FAQ

For your factory's automotive components, do you recommend using a single cutting tool for both steel and aluminum parts?

NO,Different materials are not recommended to be run through the same tool, and the cutting characteristics vary greatly of different materials, only the special tool can protect the tool life and processing precision.

Demand for PCD cutting tools and high-speed machining tools has increased significantly.
