Product Highlights
- ✅ Precision 90° Bevel Design: Enables efficient right-angle power transfer, perfect for compact mechanical assemblies and DIY models.
- ✅ Step Design for Secure Riveting: The stepped shaft section prevents the gear from slipping when riveted onto a 1/2 mm outer-diameter axle.
- ✅ Universal Module Compatibility: All 0.3M module gears can be paired together — two identical gears or two different 0.3M gears work seamlessly as a matched set.
- ✅ Copper Construction: Durable, corrosion-resistant copper ensures long-lasting performance even in intricate, fine-tolerance applications.
- ✅ Perfect for Fine Builds: Ideal for model makers, engineers, robotics enthusiasts, and makers working with micro-scale mechanical systems.
Compatibility Notes
Matching bearings and shafts are available in our store. The helical gear with a 2mm hole has an outer diameter of 3mm, fitting perfectly inside a 3mm hole — great for nested assemblies. Only gears of the same module (0.3M) can be paired together.

Frequently Asked Questions
Q: What does the "step" design on this bevel gear do?
A: The step design adds an extended shoulder section to the gear shaft. When the gear is riveted onto an axle with a 1/2mm outer diameter, this step prevents the gear from slipping or rotating freely — ensuring a firm, stable mechanical connection in your DIY build.
Q: Can I pair two identical 0.3M 12T bevel gears together?
A: Yes! Any two gears sharing the same module (0.3M) can be paired. This includes two identical 12T gears or any other combination of 0.3M gears, giving you flexible options for your 90-degree transmission assembly.
Q: How small is this gear exactly?
A: This is an extremely compact micro-scale gear — smaller than the tip of a standard toothpick. It is designed for fine-precision DIY mechanical models, miniature robotics, and micro-engineering projects where space is at an absolute premium.
