Problems solved by technology

However, the versatility of these arbors is extremely limited, as they can only be fitted with a specific manufacturer's proprietary directional drills, rather than standard directional drills which can be used when the specialized directional drills need to be replaced and are not available or Easily available when dedicated directional drills of the desired size and / or drilling configuration are not available
Additionally, such specialized arbor and directional bit systems may not fully secure the bit into the arbor and / or can allow the bit to loosen during use, resulting in off-axis oscillation, especially at high rotational speeds
Off-axis oscillation can cause undesired vibration of the directional drill bit, which can reduce the drilling life of the bit and / or create unacceptable inaccuracies during use

Embodiment Construction

[0072] exist Figure 1-4 In , an arbor embodying the invention is generally indicated by reference numeral 10 . The arbor 10 is used with hole cutters, such as hole saws and sheet metal hole cutters. As used herein, the term "hole cutter" refers to any of various types of cutting tools used to create holes in workpieces, such as hole saws, sheet metal hole cutters, and the like. As used herein, the term "arbor" refers to any of various types of devices used to support a rotating tool, such as a hole cutter, on a power tool, such as a drill, the arbor further including but Not limited to mandrels. As shown, for example in Figure 4 and 10 A typical quick-change hole cutter 12 includes: an end plate 14 defining a hole cutter hole 16 extending through a central portion of the end plate; and at least one drive pin hole 18 radially spaced relative to the hole 16 . In the illustrated embodiment, there are two drive pin holes 18 radially spaced relative to the hole 16 and angula...

Abstract

An arbor for quick change and standard hole cutters, wherein each hole cutter includes a central aperture and at least one drive pin aperture. The arbor comprises an arbor body including an end portion engageable within the central aperture, a drive shank opposite the end portion for engaging a power tool, and an aperture for receiving a pilot bit. The arbor further comprises a drive pin plate and / or collar having at least one drive pin receivable in a corresponding drive pin aperture of the hole saw for drivingly engaging the hole saw. The arbor, in at least one embodiment, further comprises a pilot bit mechanism for engaging and releasing a quick change or standard pilot bit.

Description

[0001] Cross References to Related Applications [0002] This application is the International Application (PCT) of US Application Serial No. 12 / 043,740 filed March 6, 2008, the entire contents of which are hereby incorporated by reference as part of this disclosure. technical field [0003] The present invention relates to arbors for hole cutters, hole cutters, and related methods, and more particularly, to arbors, hole cutters, and methods that facilitate relatively quick attachment of a hole cutter and / or directional drill to an arbor and The method by which hole cutters and / or directional drills are released from the arbor. Background technique [0004] A typical arbor for a hole saw includes an arbor body with a threaded end that engages a corresponding threaded hole in the hole saw end plate to secure the hole saw to the arbor. A directional drill bit is receivable within the threaded end of the arbor body and extends through the center of the hole saw. The arbor fur...
