Many fabricators confuse different PVD coatings when purchasing HSS circular saw blades. This article explains the core strengths of TiAlN coated HSS Cobalt saw blades and their matching processing scenarios, to help buyers select cost effective cutting tools.
HSS Cobalt substrate adds cobalt alloy to high-speed steel, maintaining edge hardness under high cutting temperature, far better than ordinary DMo5 HSS. The TiAlN coating is deposited via PVD technology, with oxidation resistance up to 800°C and surface hardness reaching 3400 HV, much higher than regular TiN coating. Its low friction coefficient effectively prevents chip adhesion and work hardening when cutting stainless steel, alloy steel and thick walled pipes.
Compared with uncoated blades, TiAlN coated HSS Cobalt products extend service life by over 50% and support semi dry or dry cutting to save coolant cost. They fit cold saw machines for auto parts, hardware processing and steel service centers, especially for mass production with continuous high speed cutting.
Tips for daily use: Avoid sudden overload cutting to protect the coating; store blades in dry environments to prevent rust. JINBIRD provides full size TiAlN HSS Cobalt saw blades with strict coating uniformity inspection.
