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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDDQNR toolholder style with right-hand orientation for facing and turning operations\u003c\/li\u003e\n\u003cli\u003eWedge clamping method locks DNMG 432 inserts securely under heavy cutting loads\u003c\/li\u003e\n\u003cli\u003eNegative rake angle of -6 degrees for improved insert edge strength and tool life\u003c\/li\u003e\n\u003cli\u003e1 inch by 1 inch steel shank provides rigidity and fits standard tool post bores\u003c\/li\u003e\n\u003cli\u003eOverall length of 6 inches with a 1.42-inch head length for consistent tool reach\u003c\/li\u003e\n\u003cli\u003eMulti-use designation allows rapid insert swaps across different turning programs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with DNMG 432 inserts.
