GP series solid carbide 4 flute roughing end mills are engineered for high‑efficiency roughing. The serrated cutting edges provide excellent chip evacuation, reduced cutting forces and stable performance in steel, stainless steel and alloy steel.
Solid carbide 4 flute roughing end mill for heavy‑duty roughing.
Serrated or “corn cob” cutting edge design for higher metal removal rate.
Strong core and rigid geometry to withstand heavy side milling and slotting.
Optimized flute design for smooth chip evacuation and reduced vibration.
Advanced coating options for improved wear resistance and longer tool life.
Suitable for CNC machining centers and conventional milling machines.
Roughing operations in general steel, alloy steel and tool steel.
Suitable for stainless steel roughing (please select proper grade and coating).
Side milling, slot milling and profile roughing with high feed and depth of cut.
Ideal for roughing before finishing with square end mills or corner radius end mills.
Widely used in mold & die, machinery parts, automotive and general engineering industries.
Case 1 – Roughing steel parts
Workpiece material: 45# steel
Tool: GP series solid carbide 4 flute roughing end mill, 10 mm diameter
Operation: side milling and slot roughing
Result: stable cutting, good chip evacuation and longer tool life compared with conventional roughing end mills.
Case 2 – Mold base roughing
Workpiece material: pre‑hardened mold steel (~30–35 HRC)
Operation: high‑efficiency pocket and contour roughing
Advantage: high metal removal rate with reliable performance before finishing operations.
