Description: |
| "It is advantageous to form the cutter arbor shafts in these portable power saws with a short or stub projection for supporting saw blades of normal thickness. However, upon occasion it is desirable to use cutters on these machines of substantial width—for example, dado cutters use for grooving."This invention has an object a cutter arbor shaft structure embodying an arrangement by which the shaft proper is adapted to support saw blades of normal thickness, and which may be extended to support cutters of different and substantial thickness." |
