## Feeds and Speed Calculator - Plunge Rate

Feeds and Speed Calculator - Plunge Rate. In general, a plunge rate should be less than 50% of the feed rate, due to typical end mill design. End mills are designed to cut more efficiently in lateral directions, rather than vertically (like a drill bit). Therefore, a gentler plunge rate helps to keep the temperature down and avoid damage to the ...
