Master Your Propeller FitsProfessional reaming for standard engine shafts
Modifying propellers to fit larger glow engine or electric motor shafts can be difficult without the proper equipment. Using standard drill bits often results in off-center holes or splits wooden and composite props, causing dangerous vibration and balance issues. The Great Planes 4-Step Standard Prop Shaft Reamer eliminates these risks with a stepped cutting blade design that progressively enlarges holes to 3/16", 1/4", 5/16", and 3/8" diameters.
By maintaining absolute concentricity throughout the reaming process, this RC propeller tool preserves structural integrity while ensuring your propeller sits straight on the shaft. Whether you are prepping props at the field or finishing a new build on your bench, the Great Planes 4-Step Standard Prop Shaft Reamer is a must-have accessory for every standard model engine builder.
