The Square Up is an excellent high-precision squaring device and arrow spinner tool.

Its precision is unmatched, thanks to the adjustable diamond squaring insert that makes it ideal for squaring arrow shafts or inserts.
This tool can be used hundreds to thousands of times without wearing out the diamond insert, unlike other squaring devices that require the sanding disc or cutter to be replaced after a limited number of uses.

The diamond insert is the best choice for the job. Combined with high-quality bearings and a precision-milled design, you get the perfect tool for building the most accurate arrows, resulting in significantly higher accuracy and success in the field.
