High Quality Kenners Carbide Insert MG-H12 & MG-H16 Trapezoidal and Comma Thread Blade for Lathe Machine with 3 Years Warranty
These comma-type TR trapezoidal thread inserts adopt MB-07IR internal threading structure, covering 2.0, 4.0, 5.0 and 6.0TR pitch specifications. Crafted from premium coated carbide with high rigidity, they are designed for internal trapezoidal threading and match standard toolholders precisely.
The precision-ground TR thread profile delivers accurate tooth geometry, excellent wear resistance and great chipping toughness for steel and stainless steel. The unique comma structure ensures smooth chip removal, achieving burr-free thread surface and highly consistent dimensional accuracy.
Widely suitable for internal trapezoidal threading on CNC lathes, they cover multiple common pitches for strong machining versatility. Their long service life reduces tool change downtime, lowers tooling costs and effectively improves overall threading productivity.
