Especially for 5/16 wooden shafts (prevents torque brackage while screwing on your points) and wooden shafts with high spine values or hardwoods.
Supports the optimum function of threaded arrow points. Allows to prepare arrows with minimum effort. Excellent results especially with hard surfaces like bamboo. When used with hard surfaces it is helpful to put a few drops of oil (lubricant) on the shaft. Works perfectly in combination with the assembly tool. Sizes: 5/16, 11/32, 23/64 Material: Stainless steel VA
