The specialized orientation of the insert pocket forces instant chip breaking, snapping continuous metal ribbons into compact, light swarf spirals that lift out smoothly from a minimum bore clearance of 32mm, protecting the machined surface from scratching or bird-nesting traps.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"beyond-section\"\u003e\n\u003ch2\u003e2.
