摘要： A tool that cuts a hole for a single or double electric gang” switch” box. By having four blades, all cutting at the same time and in the shape of the switch box, a more accurate and appropriately placed hole may be provided. The hole saw may be configured with two centering drills so the tool is guided into the cut. An eccentric drive mechanism converts a rotary drive into reciprocating movement of perpendicularly opposed pairs of blades to cut a rectangular opening.

摘要： A quick-release arbor is adapted for a cylindrical hole saw that has a bottom wall having a threaded central aperture and opposing indexing holes. The arbor has a central hexagonal passage with opposing key slots passing therethrough and a threaded hole saw fitting axially aligned with the hexagonal passage. The arbor has a hexagonal pilot shaft securely holding a pilot drill bit and intermediate opposing keys forming a position lock. The pilot shaft is adapted to freely pass through the passage. Within the arbor is a button chamber that is transverse to the hexagonal passage with a rear wall. A biased button is located within the button chamber having upper and lower cuts outs to permit the pilot shaft to freely pass through the cut outs of the button when the button is depressed and having rear pocket to capture one of the pilot shaft opposing keys when the button is released.

摘要： A hole cutter assembly is operable to cut a plurality of different sized diameter holes in a work piece. The hole cutter assembly includes an arbor configured to connect to a power tool for rotation about an axis, and a body coupled to the arbor for rotation with the arbor. The body defines an aperture. The hole cutter assembly includes a drill bit removably received in the aperture of the body for rotation with the arbor, an arm moveably coupled to the body, and a cutting blade coupled to the arm and moveable with the arm relative to the body. The arm is moveable relative to the body to adjust a cutting diameter of the hole cutter assembly when the drill bit is not received within the aperture. The arm is fixed relative to the body when the drill bit is received within the aperture.

摘要： The present invention relates to a hole-saw assembly (10) including a hole saw (26) having at one end a plurality of cutting teeth and at the other end two shafts. The assembly includes a mandrel (16) coaxially aligned with said hole-saw and including a body having two bores there through coaxially aligned with said shafts. An annulus (20) located on top of the body is coaxially aligned with said mandrel and hole saw and includes two holes, the annulus rotatable around its longitudinal axis from a first to a second position. In the first position the annulus holes are aligned with the bores and shafts allowing the shafts to be freely insertable and removable and in the second position the holes are misaligned to lock the shafts to the annulus. The mandrel further includes a pair of driving pins (22) adapted to engage driving apertures (24) found in hole saws especially larger ones. Typically the driving pins may biased to enable the assembly to be used even with those hole saws that do not include driving apertures and that also enables easier assembly of the device. A compressible O-ring (42) may further facilitate the operation of the assembly. This device avoids the problem of thread stripping.

摘要翻译： 本发明涉及一种孔锯组件（10），其包括在一端具有多个切割齿并且在另一端具有两个轴的孔锯（26）。 组件包括与所述孔锯同轴对准的心轴（16），并且包括具有两个孔的主体，通过与所述轴同轴对准。 位于主体顶部的环形空间（20）与所述心轴和孔锯同轴对准并且包括两个孔，所述环可围绕其纵向轴线从第一位置旋转到第二位置。 在第一位置，环形孔与孔和轴对准，允许轴可自由地插入和移除，并且在第二位置，孔不对准以将轴锁定到环空。 心轴还包括一对驱动销（22），适于与在特别较大的孔锯中发现的驱动孔（24）啮合。 通常，驱动销可能被偏置以使组件能够被使用，即使是那些不包括驱动孔的孔锯，并且也使得装置更容易组装。 可压缩O形环（42）可以进一步促进组件的操作。 该装置避免了剥线问题。

摘要： A drilling tool, such as, a drill bit or a reamer, including at least two helical flutes about the axis of said tool. The tool is remarkable in that it includes an axial channel opening out at a fixed end of the tool designed to be received in rotary drive means therefor, and a plurality of ducts connecting the axial channel to the bottom of each flute. Each duct opens out into the corresponding flute via an orifice and is inclined towards the free end of the tool, opposite to the fixed end thereof.
