Ma
ximize rigidity to reduce chatter and increase tool life by applying the following tips.
•
Choose the largest diameter possible
• Use the shortest LOC (Length of Cut) available
•
Use the toolholder which offers the shortest gage length
(3
) To control chatter, increase feed or reduce speed.
(4) For extra long endmills, reduce SFM by 25%.

ep to a minimum at all times. As runout increases, the tools’ performance decreases and tool life will be reduced.
