10pcs/set Milling cutter 3.175 Diameter CNC End Mill Cutter Mini PCB Carbide Router Bits Kit Set 2.20-3.00mm For Tools | Инструменты

Product Name: Carbide micro drill bit, made of tungsten steel, with high hardness, high wear resistance, high strength, resistance to bending, anti-breakage, etc., complete specifications. Product specifications: tool diameter 0.40-3.175MM, tool shank diameter 3.175mm. Scope of application: Suitable for circuit boards, electronics, SMT, molds, hardware processing, communications, etc. Product material: the blade part is imported tungsten steel. Features: The drill bit has a large space for chip removal; the chip removal resistance is small; the chip discharge is smooth; the hole heat is small. Extraordinary cutting edge sharpness: Due to the use of nanotechnology and advanced grinding technology, the cutting edge of the drill bit is sharper than before, which can reduce the cutting force, reduce the drilling rate and improve the quality of the hole wall. The tool design based on customer application: The variety of drill bits is available to meet different application needs. All parameters of the drill bit, such as core thickness and core taper, are carefully designed and effective; the cutting edge is strictly symmetrical: it is beneficial for efficient cutting and avoiding drilling offset                                            Delivery fixed rubber ring color random
