Abstract: A hand saw comprising a handle for actuating the hand saw and a saw blade connected to the handle and provided with a toothed cutting edge, the handle comprising a handle grip clasped by the hand of the user to impart an actuating force to the handle, and the handle grip defining a force entry direction in which the actuating force is introduced into the saw blade, wherein when the hand saw is pushed the force entry direction intersects the cutting edge of the saw blade in the region of a first quarter length of the cutting edge near to the handle or in the region of an imaginary elongation of the cutting edge into the handle.
Abstract: A device for storage and transfer of tools and supplies that includes a housing, a cover and a handle. The housing defines a storage area therein and is configured to receive a plurality of tools and supplies. The cover is pivotally attached to the housing and is movable between a closed position covering the storage area and any tools and supplies therein, and an open position at least partially exposing and permitting access to the storage area and any tools and supplies therein. The handle is pivotally attached to the housing and is movable between a storage position located within the housing and a use position projecting from the housing for carrying the device thereby. The cover is movable between the closed and open positions while the handle is either in the storage position or the use position.
Abstract: A double-sided saw blade, such as a hack saw blade, comprising a blade body defining a first end and a second end; a first cutting edge located on one side of the blade body defining a first cutting tooth set pattern and a second cutting edge located on an opposite side of the blade body defining a second cutting tooth set pattern; wherein the first set pattern and the second set pattern are (i) timed with respect to one another or (ii) 180 degrees out of phase with respect to one another. A first tooth of the first set pattern may be indexed relative to a designated reference point along the blade body and a first tooth of the second set pattern may be equally indexed relative to the same designated reference point along the blade body.
Abstract: A wood drill bit has a plurality of step sections where each step section has at least one flute that terminates in a cutting edge. The effective diameter of each of the plurality of step sections is different than the diameter of the other of the plurality of step sections such that a single bit may be used to bore holes in wood of different diameters.
Abstract: A lever bender includes a first handle pivotally attached to a second handle. The first handle includes a forming mandrel around which a pipe is bent and a stop member for receiving and substantially holding the pipe in place prior to bending. The second handle includes a forming head that engages and bends the pipe around the forming mandrel. The stop member includes a pipe-engaging member that receives a pipe and a locking member adjacent to the pipe-engaging member. The locking member includes a retaining member moveable between a projecting position where the retaining member secures the pipe between the pipe-engaging member and the locking member and a retracted position permitting a pipe to either be received within the pipe-engaging member or removed from the pipe-engaging member.
Abstract: In a crossbow-style tube bender, a curved bending mandrel having a channel into which the tube in bent to form the bent tubing length has at least one relief surface forming a localized recess or depression in the surface of the channel. A forming bar or cross bar adapted to cooperate with a bending mandrel has on a first side of the forming bar a least one first pair of forming mandrels configured for a first tubing size, and on a second side of the forming bar has at least one second pair of forming mandrels configured for a second tubing size. The bender has a quick connect-disconnect mechanism permitting quick disconnection from and connection to the forming bar to utilize either the at least one first or at least one second pairs of forming mandrels.
Abstract: A gauge protector extends about an exterior surface of the gauge. A first relatively soft zone of the protector protects the gauge from damage by shock or impact. A second relatively hard zone of the protector is located adjacent to the first relatively soft zone and is resistant to abrasion for protecting the gauge from damage by contact with abrasive surfaces.
Abstract: A kit for carrying hole saws has a hole saw carrier configured to releasably carry thereon a plurality of nested hole saws, and is movable between (i) a storage position and (ii) a use position for removing one or more hole saws therefrom. The carrier is axially-elongated and receivable through an arbor hole in a hole saw to releasably carry the hole saw thereon and to allow one hole saw to be nested within another thereon. The carrier is pivotally mounted and movable between the storage and use positions.
Abstract: A drill bit has a shank adapted to be attached to a power tool and a cutting portion adapted to drill a hole in a material. A collar is spaced along the length of the drill bit to set a depth distance that the drill bit is allowed to be inserted into a material being drilled. The drill bit further comprises a first engagement structure. A sleeve comprises a second engagement structure that is releasably engageable with the first engagement structure. The sleeve further comprises a coupling mechanism for connecting the sleeve to a fastener driver.
Abstract: A device for taking pressure readings on a HVAC system includes a first needle connectable in communication with the HVAC system for taking a first pressure reading thereof. The first needle is mounted within a first gauge and configured to self-calibrate. The device further includes a second needle connectable in communication with the HVAC system for taking a second pressure reading thereof that is independent of the first pressure reading. The second needle is mounted within a second gauge and configured to self-calibrate. A first stepper motor actuates the first needle and a second stepper motor actuates the second needle. A microcontroller controls the first and second stepper motors to move the needles to a plurality of respective positions and thereby visually confirm calibration.
