Warning :For slope drilling, please adjust cutting data acording to inclined angle

1. For inclined angle under 20 degree, reduce the feed to 50%

2. For inclined angle between 20 to 50 degree, reduce the feed to 40%, and reduce rotation to 70%

3. For inclined angle between 50 to 65 degree, reduce the feed to 30%, and reduce rotation to 70%

4. Not recommend to side milling
