Carrying the ISO code LT16ER28UN and manufacturer grade KC5010, this right-hand insert features a TiAlN coating applied via PVD process, which improves wear resistance and heat tolerance during threading operations. The insert measures 3\/8 inches inscribed circle (9.53 mm) and 0.1430 inches thick (3.44 mm). It is intended for use by machinists and CNC operators threading ferrous and high-temperature alloy workpieces where dimensional accuracy and tool life are critical.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external UN thread turning on lathes and CNC turning centers. The KC5010 grade with TiAlN coating is rated for primary workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium. It is commonly used in production threading applications where consistent thread form and insert-to-insert repeatability are required. The ER-style insert geometry is compatible with standard laydown threading toolholders designed for the LT16 insert size code.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD-applied TiAlN coating for extended tool life on hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e28 TPI external UN thread profile, right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003eISO code LT16ER28UN with 3\/8 inches inscribed circle for accurate toolholder indexing\u003c\/li\u003e\n\u003cli\u003eKC5010 manufacturer grade rated for steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eHole diameter of 0.1551 inches for secure clamping in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eCutting edge to theoretical edge length of 0.0240 inches; face of insert to tip centerline of 0.0270 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in laydown threading toolholders accepting LT16 ER-style inserts.
