Being steel, these pinion gears provide greater overall strength (as compared to brass or aluminum) ,A true maker is about integrating and repurposing. If the D-bore pinion gears just won’t fit your motor or axle that you’ve chosen to use in your project, check out these 3mm round bore gears.This MOD 0.8 pinion gear, while aesthetically unique compared to the larger pinion gears, will operate the same. Due to the small overall diameter, the set screw hole has been machined through the teeth to maximize the number of threads engaged with the set screw. While this gear is compatible with any MOD 0.8 gear, it’s most common partner is a 105 tooth hub gear. The combo will create a 7:1 ratio, underdrive or overdrive depending on whether you’re set out to increase the speed or maximize torque.
