This is a jig set for cutting Mini 4WD brake sponges and rubber pipes. The brake sponge cutter allows for straight and angled cuts on both sides. Brake sponge cuts: straight cuts at 7mm, 10mm, 13mm, and 16.6mm; angled cuts at 20°, 30°, 40°, and 50°. The rubber pipe cutter allows for angled cuts of various sizes. The jig can store the rubber pipe cutting jig or sponge brakes (50mm x 50mm size). Applying lubricating oil during cutting will make it easier. Shipped via Yu-Packet Post Mini.
