Double-edged straight bits and spiral bits' different application scenarios

Double-edged straight cutter

Material: Suitable for soft materials (such as wood, plastic) or metal processing with low precision requirements.

Processing type: slotting, contour milling, side wall processing (pay attention to vibration problems).

Disadvantages: easy to break when processing hard materials, easy to vibrate under high feed.

Double-edged spiral milling cutter

Material: strong versatility, especially suitable for metals (aluminum, copper, steel, etc.) and high precision requirements.

Processing type: cavity milling, deep groove processing, high surface quality requirements.

Advantages: more commonly used in CNC processing, compatible with high-speed cutting (HSM).
