Hole Finishing Tool Selection Guide NOTE: Surface roughness values are guidelines and depend on the application, coolant situation, machine, and cutting data applied.

Hole Finishing Application Example Cylinder Head • Four usable cutting edges per CBN insert. • CBN RIQ insert with 28,000 bore tool life. • 1,400 bores with regrindable RMS reamer. • Cost savings due to four edged full face CBN insert. • No insert back taper adjustment needed. • Same RPM at both stages saving time of spindle

Hole Finishing Application Example Cylinder Head Polished flutes chip evacuation PCD SEAT & GUIDE PARENT BORE PCDRSC04RLE Valve seat and guide parent bore machining combined. Machining center with internal coolant. • Productivity increases as same RPM applied to both seat and guide stages. • Lowest possible run out resulting in higher tool life.
