3 Core Product Lines
Engineered for the most demanding precision machining applications -- each line purpose-built for a specific material challenge.
Aluminum End Mills
Engineered for high-speed, high-precision milling in aluminum alloys. Our specialized series features optimized geometries that eliminate surface chatter and light/dark inconsistencies, delivering an ultra-clean, mirror-level finish on complex and thin-walled components.
-
Engineered geometry ensures stability when machining thin-walled profiles and large frames.
-
Mirror-grade Ra ≤ 0.2 μm roughness, eliminating surface defects and vibration lines.
-
High-polish 3-flute design with large chip pockets prevents built-up edge.
-
Premium DLC / ZrN coating prevents aluminum sticking for extended tool life.
-
Diameter range: Ø1mm - Ø25mm,with custom profile options.
Hardened Steel End Mills
Engineered to conquer hardened steels up to HRC 65, our hardened steel series delivers mirror-finish surface quality and dimensional accuracy in high-speed mold machining, eliminating the need for EDM in many applications.
-
Rated for hardness up to HRC 65+
-
Optimized cutting edge geometry for high-speed finishing
-
Ra ≤ 0.2μm surface finish achievable
-
Ball nose, flat, and radius corner variants
