3mm Nano-Coated Tungsten Carbide End Mill CNC Milling Cutter Bits | 4-Flute Micro-Grain Endmills for Stainless Steel - HRC65，Metric Size

Features

• Package Included: 1pcs 4Flute carbide metric size square end mill cutter. Suits for finishing and semi-finishing, not suggest for roughing.
• High-Performance Material: Crafted from 0.4m micrograin carbide, this end mill boasts exceptional toughness, durability, and machinability. It's designed to withstand the wear and tear of repeated use, delivering consistent performance and long-lasting reliability.
• Premium Coating for Durability: Nano caoting(TiAlSiN) belongs to a new and intelligent breed of nanocomposite materials. The foundation is still the good old TiN, with additional Al and Sielements. The outcome is a super-hard coating with outstanding toughness, along with a hot-hardness exceeding 1000C.
• Detail Design : 45 degree helix design can perform smooth surface finish, greatly Improves The Production Efficiency, Sharp And Durable, Convenient For Chip Removal.The cutting edge has been professionally passivated, which makes it more stable and resistant to collapse in hard material processing, and increases the tool life.
• General Usage: Applicable with cast iron, steels, carbon steels, alloy steels, pre-hardened steels, hardened steels, and stainless steel materials,etc. Our end mill bits are compatible with most desktop CNC machines, as well as other industrial CNC machines.
