Walter Tiger·tec Silver CVD Coating Technology: Multilayer Al2O3 Grades Explained for Steel Turning
Insert geometry gets the attention, but on a modern steel turning insert most of the productivity gain is buried in a coating stack only ten to fifteen micrometres thick. Walter’s Tiger·tec Silver family is one of the clearest examples of how a CVD multilayer architecture — rather than a single hard film — determines whether …
Turning 304 and 316 Stainless Steel: Cutting Parameters, Chip Control and Grade Selection Best Practices
Why Austenitic Stainless Steel Is Difficult to Turn Austenitic stainless steels such as AISI 304 and 316 account for a large share of CNC turning work in the medical, food equipment, chemical and marine industries. Yet they remain one of the most frequently mis-machined material families in job shops. The difficulties come from four metallurgical …

ISO P/M/K/N/S/H Carbide Grade Reference Guide: Cutting Parameters, Coatings and Application Tables Compared
Understanding the ISO Carbide Grade Classification System Every machinist and tooling engineer encounters the ISO carbide grade classification system on a daily basis, yet few fully understand how the six letter groups — P, M, K, N, S, and H — translate into real-world insert selection and cutting parameter decisions. This reference guide breaks down …
Walter Tiger·tec Silver Turning Grades Explained: CVD Coating Architecture, Grade Selection, and Cutting Parameters for Steel and Stainless Steel
Among CVD-coated carbide families for turning, few have achieved the catalogue longevity and shop-floor familiarity of Walter’s Tiger·tec Silver generation. Introduced as the successor to the original Tiger·tec grades, the Silver programme reorganised Walter’s turning assortment around a smaller set of universal grades, each covering a wide slice of the ISO application map. The result …
Walter Tiger·tec Coating Technology Explained: CVD, PVD, and Substrate Engineering for ISO P, M, K, N, S, and H Applications
Introduction to Walter Tiger·tec Coating Technology Walter’s Tiger·tec coating platform represents one of the most comprehensive coating technology portfolios in the metalcutting industry. Since its introduction, the Tiger·tec family has expanded to include multiple CVD and PVD coating systems, each engineered for specific ISO material groups and machining conditions. Unlike single-coating solutions, Tiger·tec combines carefully …
Inconel 718 Turning Best Practices: Cutting Parameters, Grade Selection, and Surface Finish Optimization
Introduction Inconel 718 remains one of the most challenging nickel-based superalloys to machine, prized in aerospace, energy, and marine applications for its exceptional high-temperature strength, corrosion resistance, and ability to retain mechanical properties at temperatures up to 700°C (1290°F). However, these same properties that make Inconel 718 indispensable also make it notoriously difficult to turn: …
ISO P/M/K/N/S/H Carbide Turning Grades: Complete Cutting Parameter Reference Guide
Introduction: Why Grade Selection Matters More Than You Think Selecting the right carbide turning grade is arguably the single most impactful decision in any turning operation. The grade determines your cutting speed, tool life, surface finish, and ultimately your cost per part. Yet many machinists rely on habit or supplier recommendations without fully understanding the …
