CNC Brass Mod 0.5 Spur & Pinion Gear Set – 20 To 60 Teeth, 4-15mm Bore – For RC Models

Tuning your RC car or building a custom project?

Here's a selection of Mod 0.5 spur and pinion gears.

They're machined from solid brass on a CNC, so they're precise and durable.

You've got a range of tooth counts from 20 teeth all the way up to 60, and the bore (center hole) varies from 4mm to 15mm to fit different motor and axle shafts.

The pitch diameter is 1.57mm.

Made in China, these are unbranded but they're a great option for hobbyists who need a specific gear ratio without paying insane prices.

Mix and match to get your roll-out just right.

Whether it's for a crawler, drift car, or a custom robot, having these on hand means you can dial in your setup perfectly.
