 |
QF– finishing
QF for finishing of general steel and alloy steel. Curved edge, sharp cutting edge, good chip control and fine surface finish due to curved edge. |
 |
 |
QM– semi-finishing
QM for semi-finishing of general steel and alloy steel. The design of step and wavy boss widens the range of chip breaking. |
 |
 |
QR- roughing cutting action
QR for rough cutting action of carbon steel,cast steel and alloy steel. Variable rake angle and land provides enough edge sharpness and strength at different depth of cut. |
 |
 |
QH- heavy cutting action
QH for heavy cutting action of carbon steel, cast steel and alloy steel. Variable land and progressive chipbreaker space, generating lower cutting force. Straight edge line with reinforcement balances strength and cutting action. |
