Review on 🔧 Tapered Pinion Diameter Module - CNBTR by Robert Espinoza

I use several pairs of these gears on my CNC plasma assembly. They are absolutely gorgeous considering the price. However, the inner hole can be a little rough, especially where the set screws are stuck and there is a slight burr from the final thread. Every one I've bought has had me filing that burr, but it took about 2 minutes and I'm done. Also, I decided to replace the set screws with socket head screws so I can use a larger hex wrench without having to remove the hex head. So far I haven't had any issues with thread damage on the gears themselves, even when actually cranking the SHCS. Overall: Great value for money, I've bought 6 or 8 of these so far.
