The Arrow Chamfering Tool (ACT) creates perfect 45 degree chamfering to the end of an arow to mate with the Reverse Tapered Shoulder of an AeroInsert-A or an AeroInsert-H. The ACT is made of steel and its grinding surface is diamond electro-plated. It’s extremely easy to use. Simply attach it to any drill, place your arrow at the center of the tool and run the drill (~1500 rpm) for approximately three seconds. Immediately after, your arrow is ready to glue in any components. To clean, just thrown it in the dishwasher, dry, and it is ready to be used again. Available in 100 grit (recommended for shops) and 180 grit (recommended for hobbyists).
