Sandvik Coromant 5730802 Indexable Turning Toolholder

Product Description

The SANDVIK COROMANT 5730802 is a right-hand indexable turning toolholder in the DCLNR style, designed to accept CNMG 432 inserts secured by a wedge clamping method. The shank measures 0.75 inches wide by 0.75 inches tall, with an overall length of 4.5 inches. The holder is constructed from steel and carries a negative rake angle of -6 degrees, making it well suited for heavy interrupted cuts and general turning operations on a CNC or manual lathe. Licensed machinists and toolroom technicians are the primary installers and users of this holder.

This toolholder is intended for facing operations in production turning environments. The wedge clamping system provides rigid, repeatable insert seating, which is critical when maintaining tight tolerances on a lathe. The head length is 1.26 inches (32.00 mm), and the back-of-bar to cutting edge distance is 4.5 inches (114.30 mm). The insert inscribed circle is 0.5 inches, corresponding to the CNMG 432 insert size. This holder is designated as a multi-use tool, accommodating a range of workpiece materials depending on the insert grade selected.

Installation Notes

Installation should be performed by a qualified machinist familiar with indexable tooling systems. Power down and lock out the lathe spindle before mounting or changing toolholders and inserts. Ensure the shank seat and clamping surfaces are clean and free of chips before securing the holder in the tool block. Handle inserts with care and use appropriate insert seating tools to avoid chipping the cutting edge during installation.
