Grewin Solid Carbide 4-Flute Flat Endmill for Steel (Wear resistant Type)
The Gewey 4-flute end mill adopts a TiSiN coating on the cutting edge, enabling direct roughing to finishing on heat-treated materials up to 55HRC. This reduces tool changes, improves machine utilization, and shortens overall production cycles. With a 0.6μm micro-grain tungsten carbide substrate, the tool offers high hardness and strength, designed specifically for high-speed and high-hardness machining applications, ensuring excellent wear resistance and extended tool life.
The tool features a fully ground cutting edge for sharp, durable performance and is versatile for machining metals, wood, and composite boards. Its large core diameter design enhances rigidity and vibration resistance, effectively reducing the risk of breakage. Meanwhile, precision-ground helical flutes provide large chip removal capacity, prevent built-up edges, and greatly improve machining efficiency.
Usage Notes:
-
Check tool runout before use; correct if exceeding 0.01mm.
-
Keep tool overhang as short as possible; if longer, reduce speed, feed, or depth of cut.
-
If abnormal vibration or noise occurs, lower cutting parameters until stable.
-
Spray or air-cooling methods are recommended for steel machining to improve tool performance and life.
