Sandvik Coromant 5732261 Ddqnr Turning Toolholder

Product Description

The SANDVIK COROMANT 5732261 is a right-hand indexable turning toolholder in the DDQNR style, designed for negative-rake facing operations on CNC lathes and turning centers. It uses a wedge clamping method to secure DNMG 432 inserts and delivers a rake angle of -6 degrees, providing stable, predictable cutting performance. The shank measures 1 inch wide by 1 inch high, with an overall length of 6 inches and a head length of 1.42 inches. Weighing 1.74 pounds, it is built from steel for rigidity under interrupted cuts and continuous facing passes. This toolholder is installed by machinists and CNC technicians in production and job-shop turning applications.

This toolholder is suited for facing operations on both ferrous and non-ferrous workpieces in residential machine shops and industrial production environments. The DDQNR style positions the insert for right-hand turning with a negative-rake geometry that extends insert life under high-feed conditions. The back of bar to cutting edge dimension is 6 inches, matching standard tool post setups on mid-range engine lathes and gang-tooled turning centers. The insert inscribed circle is 0.5 inches, compatible with standard DNMG 432 insert geometry. It is classified as a multi-use toolholder, making it adaptable across a range of turning programs with insert changes only.
