Expert Q&A: CNC Roughing End Mills

What makes a "roughing" end mill different from a standard finishing mill?
Roughing end mills feature a "scalloped" or "knuckle" cutting edge. This geometry breaks chips into smaller pieces, reducing cutting forces and allowing for much higher feed rates and depths of cut compared to smooth-edged finishing mills.
How does Millcraft ensure tool longevity in high-heat applications?
We utilize a proprietary AlTiN coating process and a heat-resistant carbide substrate. Our tools are designed to maintain edge sharpness even when running at the high RPMs required for dry machining of hardened steels.
Can you provide customized tool geometries for specific alloys?
Yes, our R&D department uses the Walter Helicheck system to develop custom flute angles and relief geometries tailored to unique materials like medical-grade plastics or aerospace-grade titanium.
What are the advantages of sourcing from a China 4.0 factory?
The primary advantages are the combination of high-tier European machinery (Walter/TTB) with the cost-efficiency and logistics speed of the Changzhou industrial cluster, providing a superior price-to-performance ratio.
