Engineers, robotics builders, and serious DIYers working on CNC machines, conveyor systems, or custom gearboxes need a bevel gear pair they can trust to mesh perfectly from day one. These 2 module, 1:1 ratio bevel gears are machined to consistent tolerances, making them a dependable drop-in for both prototype and production applications.\u003c\/p\u003e\n\u003cp\u003eEach gear is machined from steel, offering a balance of strength and machinability suited to moderate-to-high load drives. The 2 module specification defines the tooth size, with an outer diameter that scales with tooth count — approximately 54 mm (2.13 in) for the 25-tooth variant and approximately 64 mm (2.52 in) for the 30-tooth variant. Bore diameters range from 10 mm to 28 mm (0.39 in to 1.10 in) across the available size options, covering the most common shaft sizes used in DIY and light industrial applications.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include right-angle shaft drives in desktop CNC routers, bevel gear sets for robotics joint mechanisms, and 1:1 speed-ratio power transmission in custom automation rigs.
