These molds from the plastic model pros at GodHand allow you to create the perfect, flat-bottomed holes for detailing your kits!
Thanks to the center pin in each bit, no pilot hole is required, as the pin neatly prevents axle movement. You can easily carve out holes with flat bottoms instead of rounded bottoms like most tools -- just bear in mind that a tiny pin hole will stay in the center because of the center pin.
You can create two-tier molds with these bits, too, by using a smaller bit in the hole created by a larger bit! There are five sizes included in this single set, so you can do it all without buying additional tools.
Each mold has a 3mm axle thickness. A plastic case is included for safe storage of the molds.
Caution: This tool is not intended to be used for sculpting. Use as a a sculpting tool could cause damage to the blade edges.
