supports our customers with information and supplies suitable cutting conditions for each workpiece by selecting optimal
indexable insert together with the optional tool.LABEL INDICATION
TOOL LIFE
Cutting speed affects tool life. Mitsubishi’s suggests cutting speeds for 15/90-minute tool life and is based on Taylor’s equation
(Relationship for tool grade, cutting conditions and tool life). When the customer requires different tool life, obtain coefficient values of the
grade you use from the charts below. Multiply the coefficient values by the cutting speed to calculate the new cutting speed.

M Grade (Stainless Steel) cutting speed coefficient values.
K Grade (Cast lron) cutting speed coefficient values.
- (ex.)
- Medium cutting of steel
The 1st recommendation : UE6110
Indexable inserts : CNMG432MA
Recommended cutting speed: vc = 1065SFM
(Tool life : 15min.)
1065×0.82 = 873SFM
HARDNESS OF WORKPIECE
Hardness of the workpiece also affects tool life. Mitsubishi’s suggests cutting speed variations when hardness of the workpiece differs. Obtain the suitable coefficient value for each workpiece from the chart below. Multiply the coefficient value by the recommended cutting speed of the grade you use to calculate the new cutting speed.
