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)
D = ISO insert clearance (D = 15°)
Clamping of the attachment in traction 14 = Insert edge length (mm)
Marking and cleanliness C = Plain straight shank (No flats)
A = Through the tool coolant
• Check that the tool is suitable for the required use.
020 = Cutting diameter (mm)
• Inserts must be locked positively in the pocket and R = Right hand tool

on the steel product page 88. For security use a new This tool must only be used for the following applications: Face milling,
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.
