The AeroInsert-A Series


While there are actually two types of AeroInsert*, only one is a part of the AeroSystem line—AeroInsert-A (AIA). And although AIA cannot be used in the AeroConcept System, its design and characteristics are not only essential to AeroInsert-H, it is a great standalone component for those who prefer a straightforward system. 


AeroInsert-A boasts Reverse Tapered Shoulder Technology (US Patent # 8403777). 

What does that entail? First, consider the name. On any insert, whether it’s standard or a half-out, a portion remains outside the arrow. We call that portion a “shoulder,” which most significant part is where it meets with the front of a shaft. For after repeated use, any disparity in pressure at that contact point can cause mushrooming and/or splintering. There are two main reasons for these outcomes: [1] inconsistent insert and/or shaft sizing i.e. if one is narrower or wider than the other, pressure can be distributed incorrectly and [2] uneven squaring i.e. if both are not perfectly square, one or both can shift around and, again, distribute pressure irregularly. And unfortunately no matter how closely matched the sizing or how thorough the squaring, arrow failure has proven unevitable. 

But, what if those reasons could be hailed as null? If, instead of trying to avoid their causes, they could be used as an advantage? With Reverse Tapered Shoulder Technology, such is a reality. By simply preparing an arrow with a 45 degree chamfering (see our recommended Arrow Chamfering Tool below), an AeroInsert-A with a reverse 45 degree tapering can mate with it. Repeated use will only benefit concentricity—as energy and pressure from launch and/or impact transfer, the arrow further locks and sits deeper into the insert. Ultimately, sizing no longer depends past ID and squaring is no longer necessary since AIA requires chamfered shafts instead. 


The Arrow Chamfering Tool (ACT)


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, an AeroInsert-H or an AeroBushing. 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 and 180 grit.
