Engineers, machinists, and serious DIY builders working on CNC machines, robotics platforms, and industrial automation need a miter gear that holds tight tolerances under load — without corroding, seizing, or wearing prematurely. This Module 2 stainless steel bevel gear is designed for exactly those conditions.\u003c\/p\u003e\n\u003cp\u003eEach gear is machined from stainless steel and cut to Module 2 (2mm tooth pitch) specification. Available in three tooth counts — 20T, 25T, and 30T — with a 1:1 pairing ratio for true 90° miter drive. Bore sizes range from 12mm to 30mm (approximately 0.47″ to 1.18″), each paired with a precision-cut keyway (4mm, 5mm, or 8mm depending on bore) for positive shaft engagement. Sold individually (1 pcs) or as a matched pair (2 pcs).\u003c\/p\u003e\n\u003cp\u003eTypical use cases include right-angle gearbox assemblies for CNC router Z-axis drives, bevel gear sets for robotic joint actuators, and 90° shaft redirection in conveyor and indexing table mechanisms — all applications where a module 2 miter gear with keyway bore delivers consistent torque transfer without backlash creep.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e Compatible with Module 2 mating bevel gears in 1:1 ratio configurations.
