An anvil having a working end away from a mounting shank, has compressed air flowing through the anvil to feed outward to the working end. An insert fastened to a panel is secured to the panel by forming on one end of the insert and by bonding with an adhesive on the other end. The working end of the anvil presses against the insert during forming and the flowing compressed air blows excess adhesive from the contacted surface of the insert.
