APT Threading

Threading Inserts Fully Ground with High Quality PVD Coatings, Quality Machine Taps and Thread Milling Cutters

Carbide Threading Insert PVD TiAlN Coated (M30) External 0.5–3.0mm pitch 48–8 TPI Partial Profile 60°

Proflle of the cutting tip is made to a sharp point so the root of the thread will not be full form. The workpiece should be turned down before threading so that the crest forms a truncated thread to avoid interference with the mating part.

Grade T350 is NANO-TiAlSiN coated with a substrate of high wear resistance micro-grain carbide and is our preimium grade for all types of steel and stainless also good for cast iron and other materials first choice for general use.

This PVD coated grade covers P25, M25, K30, S15, H10 range of materials, suitable for dry cutting.
