This Great Planes 4-Step Standard Prop Reamer is a great way to enlarge prop holes for a perfect fit. Featuring 7mm, 8mm, 10mm and 12mm hole sizes, this reamer and is the best way to enlarge a prop hole as the reamer will not split the prop and it will keep the hole perfectly centred.

Note: This reamer is not for standard sizes, only metric.
