Engineers, robotics builders, and serious hobbyists who need a reliable 1.5 module spur gear with flexible bore and tooth-count options will find this pinion a direct fit for a wide range of drive configurations.\u003c\/p\u003e\n    \u003cp\u003eEach gear is machined to a 1.5 module standard with a circular pitch of 4.71 mm (≈ 0.185 in). Bore options span 6 mm, 8 mm, 10 mm, 12 mm, and 15 mm to accommodate common shaft diameters, while tooth counts run from 10T through 60T — covering compact high-speed pinions up to larger reduction stages. Outer diameter scales proportionally with tooth count, ranging from approximately 18 mm (10T) to 93 mm (60T).\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include 3D printer extruder and axis drives requiring a compact 1.5 mod spur gear, CNC router and laser-cutter feed-axis assemblies where a 10–60 tooth pinion gear controls linear motion, and custom robotics gearboxes where a bore 6–15 mm spur gear must mate with a standard motor shaft without additional machining.\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 to mesh with any 1.5 module (Mod 1.5) spur or rack gear.
