Magnum 3/8 Inch 4 Flute HSS End Mill Finishing Mill (EM38)

Providing the rigidity required for fine finish milling and peripheral profiling, this 4-flute HSS end mill is a staple for precision machine shops. The four-flute geometry offers increased tool strength and higher feed rate potential compared to two-flute alternatives by distributing the chip load. This creates a smoother cutting action and superior surface finish on the workpiece sidewalls.

Frequently Asked Questions

Q: Is this mill center-cutting? A: Yes, it is center-cutting and can be used for plunging and profiling.

Q: Can I use this for aluminum? A: Yes, but 2-flute mills are generally better for aluminum to prevent chip clogging; 4-flute is best for finishing.
