Read MoreRoll into cuts with a face mill as described below under Toolpath Considerations. If you dont need a square shoulder a 45 degree lead angle facemill will often leave a better finish than a 90 degree. Chips are also about 30 percent thinner versus a 90 degree facemill so faster feedrates are possible.
