As a product of Changzhou North Carbide Tool Co., Ltd. — a 17-year verified manufacturer and trader — this high polished end mill features a 45° helix angle, large capacity slot, and extreme sharpness, delivering exceptional chip removal and surface finish. With an HRC60 rating, uncoated carbide construction, and 2-6 flute options, it outperforms conventional tools in CNC machining centers. Trusted by customers in Azerbaijan, Thailand, and Poland (with a 99.5% positive review rate), this aluminum CNC milling cutter is the top choice for precision metalworking in automotive, electronics, and aerospace industries.
The cutting edge and slot feature a mirror ultra-finish (Ra ≤ 0.2um), ensuring no material residue adheres during processing. This design guarantees a smooth, burr-free surface on aluminum workpieces, eliminating the need for post-processing.
The high polished finish is tailored for aluminum and its alloys, preventing aluminum chips from sticking to the tool. This reduces downtime for cleaning and maintains consistent cutting performance.
Crafted from 100% new carbide material, the tool offers superior hardness (HRC60) and wear resistance. It withstands the demands of high-speed aluminum milling, ensuring long-term reliability and consistent precision.
Carbide’s excellent dimensional stability minimizes tool deflection during cutting, resulting in precise, consistent workpiece dimensions. This is critical for high-tolerance aluminum components.
The 45° helix angle end mill is engineered to optimize chip evacuation. The spiral design guides chips away from the cutting zone quickly, preventing clogging and reducing heat buildup — a common challenge in aluminum milling.
The 45° angle reduces cutting vibration, which enhances surface finish and extends tool life. This makes the tool ideal for both roughing and finishing operations on aluminum workpieces.
The cutting edge undergoes precision grinding to achieve extreme sharpness. This reduces cutting force to 30%-50% of conventional tools, preventing aluminum tearing and burr formation — a major issue in soft metal processing.
Lower cutting force not only improves workpiece quality but also reduces machine load and tool wear. This translates to energy savings and a longer tool service life, lowering overall production costs.
The large capacity slot of the end mill provides ample space for chips, enabling efficient chip removal even during high-speed, deep-cut milling. This design minimizes tool overheating and ensures continuous operation.
Whether processing thick aluminum blocks or thin sheets, the large slot design adapts to varying chip volumes, maintaining performance across diverse applications.
