Description of GME-PP300 Steel End Mill
GME-PP300 steel end mill for ordinary steel is an economical carbide milling cutter optimized for ordinary steels such as carbon steel, alloy steel, and low-carbon steel. It adopts a combination of a high-toughness substrate and wear-resistant coating to significantly reduce tool costs while ensuring processing efficiency. It is particularly suitable for batch processing, general parts manufacturing, and small and medium-sized mechanical processing companies.

Features of GME-PP300 Steel End Mill
• Optimized for ordinary steel and cast iron (hardness ≤ 48HRC), suitable for various efficient processing methods such as side milling, slot milling, spiral interpolation milling, cycloidal milling, etc., significantly improving metal removal rate.
The unequal pitch and unequal spiral design effectively suppress high-frequency vibration, exert superior anti-seismic ability, and achieve efficient and stable processing with large cutting depth and large cutting width.
• The variable groove depth design scientifically balances the chip removal space and tool rigidity, ensuring smooth discharge of iron chips, ensuring the overall strength during cutting, and extending the tool life.
