Large Pitch Plot Threaded Insert 27ER/IR/NR Q60/Q55/6.0/7.0/8.0ISO/TR
This 27-series large pitch flat threading insert includes 27ER external, 27IR internal and 27NR internal thread models, with Q60 and Q55 profiles and 6.0/7.0/8.0mm ISO & TR pitches. It delivers stable cutting performance for heavy-duty large pitch thread machining on CNC lathes.
Precision ground thread profile guarantees high dimensional accuracy and smooth tooth flank finish. The optimized cutting edge geometry achieves reliable chip control during large pitch threading, effectively reducing cutting force and preventing tool chipping under heavy load conditions.
Compatible with standard 27-series flat threading tool holders, these carbide inserts feature excellent wear resistance and long service life. They are widely used in heavy machinery, petroleum and construction industries for large pitch thread processing of metal parts.
