Debris collection assembly
A debris collection assembly includes a jig and an adapter insert. A front wall of the jig defines an aperture therethrough. A back wall of the jig defines an adapter opening that aligns with the aperture. The jig includes a vacuum port and defines an interior cavity that fluidly connects the aperture, the adapter opening, and the vacuum port. The adapter insert is removably loaded through the adapter opening into the interior cavity. The adapter insert either defines an orifice sized to receive a drill bit or defines a cylindrical channel sized to receive a drill bushing that defines the orifice. The orifice is oriented to allow the drill bit to extend through the aperture in the front wall to drill into a work piece. Negative pressure at the vacuum port draws airflow through the interior cavity and captures debris generated from drilling.

5 . The debris collection assembly of claim 1 , wherein the housing of the jig has ribs alternating with dimples around a perimeter of the housing.
6 . The debris collection assembly of claim 1 , further comprising a second adapter insert removably loaded through the adapter opening into the interior cavity when the first adapter insert is not coupled to the jig, the second adapter insert defining a cavity therethrough that contains an optical alignment element therein for permitting a user to visually verify that the aperture of the jig is aligned with a planned hole location on the work piece.
7 . The debris collection assembly of claim 6 , wherein the optical alignment element is a translucent solid block that is cylindrical and includes a crosshair marking thereon.
8 . The debris collection assembly of claim 1 , wherein the jig is a unitary, one-piece body that includes the housing, the flange, and the vacuum port, wherein the vacuum port is a hollow pipe that projects from the housing and is angled relative to a plane defined by the flange.
9 . The debris collection assembly of claim 1 , wherein the first adapter insert includes a first wall and a second wall that are spaced apart on opposite sides of the orifice and define a trough therebetween at a distal end of the adapter insert, wherein the trough receives the airflow that is drawn through the interior cavity of the jig to capture the debris and direct the debris towards the vacuum port.
10 . The debris collection assembly of claim 9 , wherein the trough is narrower than a diameter of the aperture of the jig and distal edges of the first and second walls of the first adapter insert are configured to break up pieces of the debris prior to the debris entering the vacuum port.
11 . A method using the debris collection assembly of claim 1 , the method comprising:
securing the jig in place relative to the work piece;
loading the first adapter insert through the adapter opening into the interior cavity of the jig;
drawing airflow, via the vacuum coupled to the vacuum port of the jig, along an air pathway that extends from an air inlet of the jig through the interior cavity to the vacuum port; and
drilling a hole in the work piece via the drill coupled to the drill bit that is within the orifice of the first adapter insert, wherein the airflow is drawn through the interior cavity to capture debris generated from drilling the hole.
12 . The method of claim 11 , wherein securing the jig in place relative to the work piece comprises coupling the clamp onto the jig and securing the clamp to the work piece via the one or more fasteners.
13 . The method of claim 12 , wherein the clamp includes a jaw and a handle that defines an elongated slot, wherein the securing the jig in place comprises (i) coupling the jaw to the jig so that the jaw at least partially surrounds the housing and contacts the back surface of the flange, and (ii) installing at least a first fastener through the elongated slot into an existing hole in the work piece to secure the clamp to the work piece.
14 . The method of claim 11 , further comprising:
loading a second adapter insert through the adapter opening into the interior cavity of the jig prior to loading the first adapter insert and after securing the jig to the work piece, wherein the second adapter insert defines a cavity therethrough that contains an optical alignment element therein; and
withdrawing the second adapter insert from the jig and replacing the second adapter insert with the first adapter insert after visually verifying, via the optical alignment element, that the aperture of the jig is aligned with a planned hole location on the work piece.
15 . The method of claim 11 , wherein both the drill and the vacuum are powered by compressed air, and the method comprises supplying compressed air to both the vacuum and the drill from a common compressed air source via an air valve.
16 . A debris collection assembly comprising:
a jig including a housing and a flange, the housing including a front wall and a back wall opposite the front wall, the front wall defining an aperture therethrough, the back wall defining an adapter opening that aligns with the aperture in the front wall, wherein the jig includes a vacuum port configured to attach to a vacuum tube, the jig defining an interior cavity that fluidly connects the aperture, the adapter opening, and the vacuum port, wherein the flange protrudes from the front wall of the housing beyond one or more edges of the housing;
a first adapter insert removably loaded through the adapter opening into the interior cavity, the first adapter insert one of (i) defining an orifice therethrough that is sized to receive a drill bit or (ii) defining a cylindrical channel that is sized to receive a drill bushing that defines the orifice, the orifice oriented to allow the drill bit to extend through the aperture in the front wall to drill into a work piece, wherein negative pressure at the vacuum port draws airflow through the interior cavity and captures debris generated from drilling; and
