     BACKGROUND OF THE INVENTION 
     (1) Field of the Invention 
     The disclosure relates to driving bit devices and more particularly pertains to a new driving bit device for installing an anchor fastener. The present invention discloses a driving bit device comprising a shaft having a first end configured to engage a head of an anchor fastener and a second end adapted to be engageable to a chuck of a hammer drill 
     (2) Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98 
     The prior art relates to driving bit devices, which may comprise devices that engage both drill bits and anchor fasteners and which translate rotation of the drill bits into a percussive force upon the anchor fasteners. Prior art relates driving bit devices also may comprise sleeves, which are positionable around anchor fasteners for guiding percussive rams or are positionable over drill bits for adapting them to engage anchor fasteners. What is lacking in the prior art is a driving bit device comprising a shaft having a first end configured to engage a head of an anchor fastener and a second end adapted to be engageable to a chuck of a hammer drill. 
     BRIEF SUMMARY OF THE INVENTION 
     An embodiment of the disclosure meets the needs presented above by generally comprising a shaft. A first end of the shaft has a first recess extending axially thereinto. The first recess is arcuate and thus is complementary to and configured for insertion of a head of an anchor fastener. A second end of the shaft is configured to engage a chuck of a hammer drill so that the shaft is operationally engaged to the hammer drill. The shaft is configured to engage the head of the anchor fastener, such that, with the anchor fastener positioned through a first hole in a first substrate, the hammer drill is positioned to drive the anchor fastener into a second hole in a second substrate. The anchor fastener expands to engage a wall of the second hole to couple the first substrate to the second substrate. 
     There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto. 
     The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.

     (j) DETAILED DESCRIPTION OF THE INVENTION 
     With reference now to the drawings, and in particular to  FIGS. 1 through 8  thereof, a new driving bit device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral  10  will be described. 
     As best illustrated in  FIGS. 1 through 8 , the hammer drill driving bit device  10  generally comprises a shaft  12 . The shaft  12  comprises a first section  14  and a second section  16 , with the first section  14  extending from a first end  18  toward a second end  20  of the shaft  12 . The second section  16  extends from the second end  20  to the first section  14 . The first section  14  is circumferentially larger than the second section  16 , as shown in  FIG. 4 . The first section  14  is tapered proximate to the second section  16 , such that there is a smooth transition between the first section  14  and the second section  16 . The shaft  12  comprises steel. The shaft  12  may comprise hardened steel. 
     The first end  18  of the shaft  12  has a first recess  22  extending axially thereinto. The first recess  22  is arcuate and thus is complementary to and configured for insertion of a head  24  of an anchor fastener  26 , as shown in  FIG. 6 . The anchor fastener  26  may include a crimp anchor, a split drive anchor, a spike anchor, or the like. 
     The second end  20  of the shaft  12  is configured to engage a chuck  28  of a hammer drill  30 , as shown in  FIGS. 7 and 8 , so that the shaft  12  is operationally engaged to the hammer drill  30 . The shaft  12  is configured to engage the head  24  of the anchor fastener  26 , such that, with the anchor fastener  26  positioned through a first hole in a first substrate, the hammer drill  30  is positioned to drive the anchor fastener  26  into a second hole in a second substrate, such as concrete. The anchor fastener  26  expands to engage a wall of the second hole to couple the first substrate to the second substrate. 
     The first end  18  of the shaft  12  is beveled, as shown in  FIG. 6 . The first end  18  being beveled allows the anchor fastener  26  to be driven into the second hole to a point where the head  24  of the anchor fastener  26  engages the first substrate. 
     The first recess  22  has a second recess  32  extending therefrom axially into the shaft  12 . The second recess  32  is disc shaped and thus is complementary to and configured for insertion of a head  34  of a pin  36  of the anchor fastener  26 . The shaft  12  thus is configured to engage the head  34  of the pin  36 . The second recess  32  may extend into the shaft  12  so that the second recess  32  is configured for insertion of approximately one half of the head  34  of the pin  36 . 
     With a sleeve  38  of the anchor fastener  26  positioned through the first hole in the first substrate and extending into the second hole in the second substrate, the hammer drill  30  is positioned to drive the pin  36  into the sleeve  38  to expand the sleeve  38 . The sleeve  38  engages the wall of the second hole to couple the first substrate to the second substrate. With the first recess  22  being arcuate, it also is complementary to and configured for insertion of a head  40  of the sleeve  38  as the pin  36  is driven into the sleeve  38 . The anchor fastener  26  includes, but is not limited to, a drive pin rivet, a hammer drive anchor, or the like. 
     In use, the first substrate is abutted to the second substrate so that the first hole is aligned with the second hole. The sleeve  38  of the anchor fastener  26  is inserted through the first hole into the second hole. The head  34  of the pin  36  then is inserted into the second recess  32  and the hammer drill  30  is actuated to drive the pin  36  into the sleeve  38  to a point where the head  34  of the pin  36  meets the head  40  of the sleeve  38 , the head  40  of the sleeve  38  engages the first substrate, and the head  40  of the sleeve  38  is positioned in the first recess  22 . The first substrate thus is coupled to the second substrate. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure. 
     Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
