    A hole saw assembly including an arbor which comprises a stem, a body, a pilot drill carried by the body, and spring-loaded connecting means adapted to engage appropriate complemental locking means in the base of the cup-shaped hole saw. The hole saw has appropriate arcuate apertures in its base and appropriate inclined ramps which will, upon insertion and twisting movement of the arbor relatively of the saw, permit the spring-loaded locking means to be engaged by the ramps and snapped into place so as to secure the saw to the arbor in secure flush position. A modified form of the invention is also disclosed in which the spring-loaded locking means include fixed T-shaped studs or pins and ball detent means which also engage the base of the saw.

    The invention can be used in the woodworking industry. A known tool for cutting holes includes a drill on a right side, having a mandrel with connecting elements in contact with surfaces and a cylindrical saw with cutting teeth 1. A disadvantage of such a tool is the difficulty of connecting the mandrel with a / cylindrical saw. Also known is a tool for cutting holes, which include a flat contact surface of a mandrel with symmetrically longitudinal axis of the tool, having 1 special elements and a circular saw with cutting teeth and shaped grooves and a guide drill, and the connecting elements are in the form of pins hovkgiit, and shaped grooves have holes for these heads 2. The disadvantage of such a tool is the low reliability of the connection of the mandrel with a cylindrical saw, the purpose of the invention is to increase ezhnosti compound mandrel. cylindrical saw. This is achieved by the fact that the pins are spring-loaded with respect to the mandrel, and the holes for the heads of the pins are located in the middle part of the figured grooves; at THIS, the thickness of the cylindrical saw is made increasing from the middle part of the figured grooves to the periphery. FIG. 1 shows a tool for cutting holes; figure 2 is the same in the collection; on .fig:: 3- the same, bottom view; in fig. 4 is the same, section A-A in FIG. 2 ,. The tool contains a mandrel 1 with a spike 2, connecting elements - pins 3 having heads 4, a guide drill 5, a cylindrical saw 6 having a gear 7 and figured grooves 8 with holes 9, and the thickness of the cylindrical saw 6 at its attachment point mandrel, i.e. in the area of the shaped grooves, increasing from the middle part to the periphery. Windows 10 are made to exit the chips in the cylindrical plate 6. The pins 3 are spring-loaded relative to the mandrel
