    Abstract: A hole cutter can include a cylindrical blade body with a cutting edge and one or more axially-elongated apertures. Each axially-elongated aperture can include a first fulcrum axially spaced from the cutting edge, and a second fulcrum axially spaced further away from the cutting edge than the first fulcrum. The blade body can also include a third fulcrum defined by a second aperture different from the one or more axially-elongated apertures. The third fulcrum may be spaced closer to the cutting than the first and second fulcrums. A lever, such as a screw driver, can be inserted into the apertures and placed against each of the fulcrums to lever slugs out of the interior of the blade body. The third fulcrum may alternatively be defined by another axially-elongated aperture that is located a different distance from the cutting edge than the axially-elongated aperture containing the first and second fulcrums.

    Abstract: A hole cutter has a cylindrical blade body including a cutting edge and one or more axially-elongated apertures formed within a side wall of the blade body. The axially-elongated aperture is configured to receive a lever, such as a screwdriver, therethrough. Each axially-elongated aperture includes a first fulcrum axially spaced adjacent to the cutting edge, a second fulcrum axially spaced further away from the cutting edge than the first fulcrum, and optionally a third fulcrum axially spaced between the first and second fulcrums. A lever, such as a screwdriver, can be inserted into the aperture and placed against each of the fulcrums to lever slugs out of the interior of the blade body.

    Abstract: A tape measure may include a housing including an interior space and a brake opening in communication with the interior space, a reel rotatably supported within the interior space, a tape blade at least partially wound on the reel, and a finger brake positioned adjacent the brake opening. The finger brake may include a support frame attached to the housing and including a frame opening, and a flexible member attached to the support frame and extending over the frame opening. The flexible member may be configured to deflect or elastically deform from a released position in which the flexible member is spaced apart from the tape blade to an engaged position in which at least a portion of the flexible member contacts a portion of the tape blade.

    Abstract: Compact tube and pipe expanders and flaring tools requiring reduced actuation force by a user. A flaring tool includes a flaring block and a yoke clampable to the flaring block by a clamping mechanism. The yoke includes a housing having a threaded release portion movable between a first position and a second position. A flaring cone of the yoke has a tapered flaring surface adapted to engage an internal surface of a tube and deform at least the engaged portion of the tube against the flaring block into a flared condition. A threaded feed screw is operatively coupleable to the flaring cone to move the flaring cone into engagement with the internal surface of the tube to deform it. The tool has a handle to rotate the feed screw.

    Abstract: A locking pliers has a first jaw and a second jaw movable with respect to one another. A locking mechanism locks the first jaw and the second jaw in position relative to one another. At least one of the jaws is provided with an attachment structure that allows a variety of work holders to be removably or permanently attached to the jaw. At least one of the jaws may be provided with a receiving surface that allows a surface of a variety of different types of work holders to be attached to the jaw such as by welding.
