This expandable hole punch is a precision tool designed for drilling and enlarging holes in RC car bodies, boat hulls, and model aircraft. The reamer expands from 0 to 14 mm, allowing you to create exhaust ports, body post holes, aerial holes, and other custom openings with controlled sizing.
Made from high strength steel, the tool resists wear and deformation even with repeated use. The hollow handle design keeps the tool lightweight and easy to grip for extended work sessions. A knurled surface provides secure anti-slip handling, while the integrated size indicator helps you dial in the exact hole diameter you need.
The compact 130 x 17 mm form factor fits comfortably in any toolbox or hobby workspace. Whether you’re customising RC models or performing general hobby drilling tasks, this reamer delivers the precision and durability expected from a professional-grade DIY tool.
