    · Speed Choice: Refer to recommended cutting speeds
    · Feed recommendation: 0.06-0.18mm/cycle. Feed is the key point for hole cutting. Different feed forms different shaped chips, which determine the performance of chips removal
    · During the beginning and temination of hole cutting, decress feed 1/3 can reduce the damage of cutter
    · Sufficien coolant supply can increase the smoothness of holes and quantities of holes to be cut
    · Some materials like cast iron/copper occur lots of powder when cutting, Compressed air is recommended for cooling instead og coolant
    · Remove the chips twining around the cutter promptly, which is the better way for chip removal. Better chips removal is quite important
    · Withdraw the cutter when it still rotates after hole drilling
    · Clear the chips after hole drilling
    · For multi-layer work pieces, clear the chips after every layer drilling
    · When the wear width of the cutting edges reaches 0.4mm, cutter should be replaced
