Faster Feed Rate: Three-flute design allows for higher cutting speeds in soft metals. Increases efficiency while maintaining accuracy in fast-paced machining environments Lasting Sharpness: Solid carbide material retains edge strength across cycles. Reduces tool wear and boosts consistency even with frequent high-speed use Smooth, Clean Finish: Extra flute contact improves cut stability and reduces burrs. Eliminates surface imperfections, so parts come off the machine closer to finished Avoid Chip Jams: Flute geometry helps eject chips smoothly in aluminum and brass. Prevents melting, sticking, and the frustration of mid-cut interruptions Pro-Level Quality: SHARPRO Hold tight +0.02 mm tolerance with serialized tracking and high-precision machining to ensure consistent performance and professional results SHARPRO Carbide Square End Mill for Aluminum Cutting Extra Long Reach 3 Flute 4mm Shank 4mm Cutting Dia. 60mm OVL.
