Description
The OSG Carbide 3 Flute End Mill with a corner radius and DLC coating is a precision cutting tool designed for aluminum machining. It’s built to deliver stable, accurate performance across a range of aluminum milling tasks.
With a 3 mm diameter and an R0.25 corner radius, this end mill features three flutes that efficiently remove material while maintaining control and rigidity. The Diamond-Like Carbon (DLC) coating enhances wear resistance and tool longevity, making it a durable choice for demanding aluminum work.
- Three-flute design for efficient material removal: The three flutes provide fast and steady aluminum removal while maintaining rigidity for smooth cuts and reliable chip evacuation.
- Corner radius for precision and finishing: The R0.25 corner radius helps produce clean inside corners and reduces edge chipping, delivering consistent, high-quality results in aluminum parts.
- DLC coating for longer tool life and wear resistance: The Diamond-Like Carbon coating extends tool life and resists wear in demanding aluminum machining, reducing tool changes and downtime.
By combining a DLC-coated carbide body with a compact 3 mm diameter and a precise R0.25 corner radius, this end mill supports quick, controlled material removal, long tool life, and consistent results— helping you finish aluminum projects faster with fewer tool changes and less rework.
