Value Collection TCN35800B Grooving Insert TNMC43 TCN55

Product Description

The VALUE COLLECTION TCN35800B is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC and manual lathes. Built to TNMC43 insert style specifications, this left-hand insert carries a TCN55 manufacturer grade and a C5 material grade carbide substrate. It delivers a cutting width of 0.125 inches and a maximum depth of cut of 0.204 inches. Weighing just 0.02 pounds, the insert is compact and engineered for consistent chip control and dimensional accuracy in production turning environments. It is intended for use by machinists and tool-and-die professionals working in shops requiring repeatable groove geometry.

This grooving insert is suited for residential shop, production machining, and job-shop lathe applications where left-hand grooving, parting, or profile work is required. The TNMC43 insert style fits toolholders designed for that seating geometry. The TCN55 grade is appropriate for a range of ferrous and non-ferrous grooving applications. The 1/2-inch inscribed circle dimension and the 43 insert size designation help machinists confirm correct holder compatibility before installation. Maximum depth of cut range spans 0.200 inches to 0.300 inches, giving operators flexibility across multiple groove depth requirements.

Installation Notes

Insert replacement and indexing should be performed by a qualified machinist with the machine powered off and all spindle rotation stopped. Use the correct torque wrench or insert clamp tool specified by the toolholder manufacturer to secure the insert — do not overtighten by hand. Inspect the insert pocket for debris or damage before seating a new insert. Follow applicable shop safety procedures and machine tool manufacturer guidelines during any tooling change.
