The Last Chance Archery Square Up is an excellent new high-precision squaring device and arrow spinner tool. It uses an adjustable diamond squaring insert that is the perfect solution for squaring arrow shafts or inserts. You can use this tool hundreds to thousands of times without wearing out the diamond insert. With other squaring devices, the sanding disc or the cutter must be changed out after limited uses, not with the Square Up. The diamond insert is the only way to go and is the correct tool for the job. Combine the diamond insert with high-quality bearings and a precision-milled tool, and you have the perfect combo to help build the most accurate arrow possible, which results in much higher accuracy and success in the field.FeaturesHigh-precision squaring device Adjustable diamond insert for squaringArrow spinner High-quality, smooth bearings Square shafts or inserts Spin any shaft to check straightnessPrecision milled tool Includes1 - Square Up 2 - Lag Bolts 2 &...
