     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0013]    With reference now to the drawings, and in particular to  FIGS. 1 through 7  thereof, a new cutting device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral  10  will be described. 
         [0014]    As best illustrated in  FIGS. 1 through 7 , the multipurpose cutting assembly  10  generally comprises a mount  12  that may be removably coupled to a turret of a computer numerical control assembly  14 . The turret of a computer numerical control assembly  14  may be of any conventional design. The mount  12  comprises a holder  16  that has a first end  18 , a second end  20  and a peripheral surface  22  extending between the first end  18  and the second end  20 . The peripheral surface  22  has an upper side  24 , a lower side  26 , a first lateral side  28  and a second lateral side  30 . The holder  16  is elongated between the first end  18  and the second end  20  and the first lateral side  28  has a lobed portion  32 . The lobed portion  32  is positioned adjacent to the second end  20  and the upper  24  and lower  26  sides extend onto the lobed portion. 
         [0015]    The upper side  24  has a receiver  34  coupled to and extending upwardly therefrom and the receiver  34  is substantially positioned on the lobed portion  32 . The receiver  34  has a distal end  36  with respect to the upper side  24  and the holder  16  has an aperture  38  extending through the distal end  36  of the receiver  34  and the lower side  26 . The aperture  38  has a first section  40  and a second section  42  and the first section  40  extends between the distal end  36  and a point that is closer to the upper side  24  than the distal end  36 . The aperture  38  has a bounding surface  44  and the bounding surface  44  corresponding to the first section  40  tapers inwardly between the distal end  36  and the second section  42 . The second section  42  extends between the first section  40  and the lower side  26 . The bounding surface  44  corresponding to the second section  42  is threaded between the lower side  26  and a point that is closer to the lower side  26  than the first section  40 . 
         [0016]    The holder  16  may be removably fastened to an exposed side  46  of the turret of a computer numerical control assembly  14 . The holder  16  is positioned to have the lower side  26  abut the exposed side  46  of the turret of a computer numerical control assembly  14  such that the receiver  34  is positioned adjacent to an outer edge  48  of the turret of a computer numerical control assembly  14 . At least one fastener  50  extends through the holder  16  and engages the exposed side  46  to retain the holder  16  on the exposed side  46 . The fastener  50  may be a bolt or the like and the holder  16  may comprise an ER  16  holder or the like. 
         [0017]    A collet  52  is provided that has top end  54 , a bottom end  56  and a peripheral wall  58  extending therebetween. The top end  54  and the bottom end  56  are open and the collet  52  is substantially hollow. The peripheral wall  58  has an outer surface  60  and the outer surface  60  of the peripheral wall  58  tapers inwardly between the top end  54  and the bottom end  56 . The collet  52  is removably positioned within the first section  40  of the aperture  38  such that the outer surface  60  abuts the bounding surface  44 . The bounding surface  44  of the first section  40  restricts the collet  52  from moving into the second section  42 . The collet  52  may comprise an ER 16 collet manufactured by Royal Products, 200 Oser Avenue, Hauppague, N.Y., 11788 or the like. 
         [0018]    A plug  62  is provided that has a pair of ends  64  and an outermost surface  66  extending therebetween. Each of the ends  64  has a groove  68  extending inwardly toward a center  70  of the plug  62 . The outermost surface  66  threadably engages the bounding surface  44  of the second section  42 . A nut  72  threadably engages an exterior surface  74  of the receiver  34  and the nut  72  retains the collet  52  within the receiver  34 . 
         [0019]    A plurality of fittings  76  is provided and each of the fittings  76  has a primary end  78  and a secondary end  80 . Each of the fittings  76  is elongated between the primary end  78  and the secondary end  80  and each of the fittings  76  has a unique cutting section  82  extending from the secondary end  80  toward the primary end  78 . Each of the fittings  76  has a tab  84  coupled to and extending away from the primary end  78 . The primary end  78  of a selected one of the fittings  76  is directed through the collet  52  after the collet  52  is positioned within the aperture  38  such that the tab  84  engages the groove  68  in the plug  62 . 
         [0020]    The plug  62  is rotated in the aperture  38  such that the cutting section  82  is positioned at a selected orientation with respect to an axis extending through the distal end  36  of the receiver  34  and the lower side  26  of the holder  16 . The nut  72  is tightened on the receiver  34  such that the selected fitting  76  is compressed within the collet  52  thereby retaining the cutting section  82  at the selected orientation. The fittings  76  may comprise a center drill  86 , a drill  88 , a reamer  90 , an end mill  92 , a tap  94 , a boring bar  96 , a grooving bar  98 , a threading bar  100 , a cutting bar  102  and a trepanning bar  104 . 
         [0021]    In use, the holder  16  is fastened to the exposed side  46  of the turret of a computer numerical control assembly  14 . The collet  52  is inserted into the first section  40  of the aperture  38 . The primary end  78  of the selected fitting  76  is inserted into the aperture  38  until the tab  84  engages the groove  68  in the plug  62 . The nut  72  is slid over the selected fitting  76  to threadably engage the receiver  34 . The plug  62  is rotated until the cutting section  82  of the fitting  76  is positioned at the selected orientation. The nut  72  is tightened to retain the fitting  76  at the selected orientation. 
         [0022]    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. 
         [0023]    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.
