1:2 Brass Bevel Gear Set - 1M Module 20T-40T 90-Degree Right Angle Gears For DIY Projects

These brass bevel gears are perfect for your mechanical projects! The 1:2 ratio means one gear turns twice for every rotation of the other - great for speed reduction or torque increase. Made from solid brass that's durable and corrosion-resistant.

The set includes 20-tooth and 40-tooth gears with different hole sizes (8mm and 6mm) for flexible mounting options. The 1M module ensures precise tooth engagement without skipping or slipping. The 90-degree angle transmission is perfect for changing direction in compact spaces.

Great for robotics, model making, precision instruments, or any mechanical application needing reliable right-angle power transmission. The brass construction handles high loads and torque without wearing out. Much better quality than 3D-printed or plastic gears for serious projects!
