Makers, hobbyists, and small-workshop engineers who build their own motion systems need a spur gear that holds tight tolerances, resists wear, and ships in the exact tooth count they need — without ordering a full assortment just to find the right fit.\u003c\/p\u003e\n    \u003cp\u003eThese 2.5 module spur gears are machined from 45# carbon steel, a medium-carbon alloy known for its balance of hardness and machinability. The flat-gear (no hub) profile keeps the axial footprint compact. Outside diameters span 30 mm (≈1.18 in) for the 10-tooth variant up to 80 mm (≈3.15 in) for the 30-tooth variant, with tooth counts available in every step from 10T through 30T. Bore diameter and keyway dimensions vary by tooth count — see variant options for exact bore specs.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include DIY CNC axis drives where a 2.5 mod gear pair delivers smooth, low-backlash motion; open-frame robotics joints that need a compact flat gear for space-constrained assemblies; and custom conveyor or indexing mechanisms in maker workshops where off-the-shelf gearboxes are oversized or overpriced. The multi-piece packing options (1, 2, 3, or 5 pcs) let you stock matched pairs or full gear trains in a single order.\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 Module 2.5 (Mod 2.5) gear systems.
