65-Degree Metal Ceramic Ball End Milling Cutter Non-coated Vertical 2 Cutting R1.5 R2.5 R3 OEM Customizable Mirror Machining
This 65° helix cermet ball nose end mill series features a 2-flute design with radius specifications R1.5, R2.5 and R3. Engineered for CNC mirror-level precision finishing, it delivers exceptional surface quality on contoured and 3D curved surfaces of carbon steel and alloy steel.
The 65° helix angle reduces cutting vibration and ensures smooth shearing action. Premium cermet substrate features ultra-low friction and excellent wear resistance, effectively suppressing built-up edge and consistently achieving Ra ≤ 0.8μm mirror-like surface finish without secondary polishing.
Compatible with standard CNC tool holders, these end mills are widely applied in precision mold making, automotive parts and electronic component manufacturing. They deliver stable repeatable finishing quality, offering a highly efficient and cost-effective solution for fine contour machining.
