Technical Information
Recommendations for High Speed Machining The Cutter Nomenclature Code:
at 8,000 rpm or above.
Example: 5702VZD14CA020R58-2
• Check spindle condition:
5702 = Stellram Product Family
Runout V = Screw fixation
Balancing Z = Insert shape (parallelogram)
Clamping of the attachment in traction D = ISO insert clearance (D = 15°)
Marking and cleanliness 14 = Insert edge length (mm)
C = Plain straight shank (No flats)
• Check that the tool is suitable for the required use. A = Through the tool coolant
020 = Cutting diameter (mm)
• Inserts must be locked positively in the pocket and R = Right hand tool
58 = Reach of tool in mm

be torqued to the correct value as indicated in our charts
on the steel product page 78. This tool must only be used for the following applications: Face milling,
For security use a new screw each time. shoulder milling, slotting and pocketing.
• Check the balancing of the – assembled tool – cutter
body, inserts and attachment.
• Before start up, note the maximum RPM engraved on Cylindrical shanks & HSK shanks (special): 5702VZD14 and 5720VZ16 are
designed and balanced to G6.3 at 30,000 rpm for diameters 50mm and below.

RPM is linked to a precise balancing value. shank tools mounted in a shrink fit holder or any other mill chuck holder + inserts
+ screws must be re-inspected for balance by the end user when exceeding 8,000
• Ensure that the field of application of the tool shown in rpm. End user must balance the assembly to a G6.3 value minimum.
