Makers, robotics builders, and CNC hobbyists who demand repeatable, low-backlash right-angle drives will find these 90° miter bevel gears a reliable foundation for any shaft-to-shaft power transfer project.\u003c\/p\u003e\n\u003cp\u003eEach gear is machined from carbon steel with a natural metallic finish, available in three module sizes — Mod 1, Mod 1.5, and Mod 2 — and tooth counts ranging from 15T to 30T. Bore diameters span 5 mm (≈0.197 in) through 25 mm (≈0.984 in), covering the most common shaft sizes used in hobby and light-industrial applications. Pairing options include 1:1 (same-tooth matched sets) and 1:02 (2:1 reduction sets), sold individually so you can mix and match to your exact ratio requirement.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include right-angle gearbox builds for 3D-printed robotics arms, stepper-motor driven CNC axis redirects, RC vehicle differential assemblies, and custom conveyor corner drives — all scenarios where a compact 90° bevel gear pair replaces bulky belt or chain routing.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Designed for 90° shaft intersection drives.

Mod 1 suits lighter loads and compact builds (e.g., small robotics); Mod 1.5 is a mid-range choice for moderate torque; Mod 2 handles heavier loads and larger shaft diameters.

Exact load ratings depend on module size, tooth count, operating speed, and lubrication. Mod 2 gears with higher tooth counts (25T–30T) offer the greatest torque capacity in this range.

The 1:2 pairing combines a smaller driver gear with a larger driven gear (e.g., 15T driving 30T), halving the output RPM and doubling the output torque relative to the input.
