About CPT GmbH
CPT GmbH, based in Freiberg am Neckar, develops and produces precision cutting tools with a focus on thread turning, thread milling, drilling and grooving. The product range includes threading inserts, threading tool holders, carbide thread mills, taps, solid carbide drills, mini countersinking/chamfering tools, thread whirl (whirling) tools and customer-specific special tools with fast production and delivery. All inserts are 100% profile-ground directly after the sintering process; the tools are made from ultra-fine-grain carbide, some with PVD coatings (e.g. TiAlN, triple-layer coating). The tools are used in demanding materials up to 62 HRc, including hardened steel, titanium alloys, superalloys such as Hastelloy and Inconel, stainless steel, cast iron and aluminium. Customer industries include in particular medical technology and aerospace, supplemented by general machining production. A comprehensive quality management system with certifications according to ISO 9001:2015, ISO 14001:2004, ISO 13485:2003 and OHSAS 18001 ensures the required product quality.
