4 Flutes Long Neck Flat End Mill

DLC Coating Offers Excellent Anti-Adhesion and Extended Tool Life

The DLC coating dramatically reduces friction and prevents built-up edge during soft metal machining—especially red copper and aluminum alloys. This ensures cleaner cuts, superior surface finishes, and longer tool life, even under dry or MQL conditions.

Long Neck Geometry for Extended Reach in Deep Cavities

The extended neck design enables effective machining of narrow slots, deep pockets, and complex mold cavities without tool interference. Ideal for precision mold-making, micro-feature processing, and electronic part machining where accessibility and rigidity are equally critical.

4-Flute Structure Enhances Feed Rates and Surface Quality

With four cutting edges, the end mill distributes cutting forces more evenly, allowing for higher feed rates and improved surface finish. This makes it ideal for semi-finishing and finishing operations in non-ferrous materials such as copper and aluminum, as well as in plastic and resin composites.

Flat-End Design Ensures Clean Bottom Surfaces and Sharp Contours

The square-end geometry provides precise control in bottom-face machining, step finishing, slotting, and contour profiling. Especially effective when flatness and accuracy are essential in copper electrodes, resin housings, or lightweight aluminum parts.

Polished Flute Surfaces Improve Chip Evacuation and Reduce Heat Buildup

Highly polished flutes minimize chip adhesion and promote efficient chip removal. This enhances thermal control during high-speed operations, reducing the risk of chip packing or material smearing in soft, sticky materials like pure copper.

Material-Specific Cutting Parameters Provided for Setup Accuracy

Each end mill comes with recommended cutting data for copper, aluminum, and engineering plastics—including cutting speed, feed rate, and depth of cut. This simplifies setup, improves reliability, and maximizes tool performance from the outset.
