  • Patent number: 6712368
    Abstract: A quick release attachment tool where the rotary tool has a housing which encloses a motor with the housing having a central axis, a non-operational end portion and an operational end portion. A nose portion is formed at the operational end portion, and the nose portion has an outer annular groove disposed generally perpendicularly to the axis. The nose portion also has a non-circular element at the outer end thereof coaxial with the central axis. A rotatable shaft is connected to the motor and located along the central axis. The attachment tool includes a central cavity, an attachment end portion and a working end portion. A non-circular mating element is formed in the central cavity that matingly engages the non-circular element of the rotary tool. There is also a biased connection element provided on the attachment tool, which faces the central cavity. This biased connection element engages the annular groove of the nose portion when the attachment tool is fitted onto the rotary tool.

  • Patent number: 6668463
    Abstract: A cutting and grinding tool for removing grout from between tiles comprises a rotatable cutting disc formed with a plurality of radially extending teeth about the circumference of the disc. A drive gear engagable with the teeth is rotated by a power drill to exert a drive force to rotate the cutting disc. The disc teeth serve a dual function of performing a cutting and grinding operation and transmitting the drive force of the drive gear to rotate to the disc. The tool is simple in construction, reliable in operation and easy to control in order to efficiently remove grout from between tiles.

  • Publication number: 20030233923
    Abstract: A woodworking drill includes a slab-shaped blade and a blade handle connected behind a body of the blade. The top of the blade is shaped as a point of blade with shoulders on both sides of the point of blade. On the edge of the point of blade, the shoulder cutting faces and the blade that contact with the working object set the cutting guiding angles. A bending mechanism in the same direction of the drill's rotation is designed on both shoulder cutting faces. This design reduces contacting resistance or cutting resistance between bended shoulder cutting faces and working objects and enhances efficiency of clearing out saw dust. With the bended shoulder cutting faces, the drill can clear out saw dust more effectively, enhance cutting speed and working performance as well as prevent the abrasion to the drill.

  • Patent number: 6656626
    Abstract: A battery release mechanism for releasably securing a battery to a power tool is disclosed. The battery release mechanism includes a battery receiving portion integral with a handle portion of the power tool and an attachment portion integral with the battery. The attachment portion is configured to engage the battery receiving portion. The battery release mechanism also includes a closure member that is operable with and transversely disposed within the battery receiving portion. The closure member is configured to secure the battery within the battery receiving portion when the closure member is in a “lock” position. The closure member has a first end and a second end opposite the first end. The first end is disposed through a side wall of the tool housing and defines a push button for selectively moving the closure member from the “lock” position to a “release” position.

  • Patent number: 6651348
    Abstract: A drill powered reciprocating saw including a safety gear assembly which disengages the saw's drive mechanism should the operator lose his or her grip on the saw housing. The gear assembly includes a motor drive shaft that is connected to an electric drill and which drives a jackshaft by means of a pair of interlocking gears. At rest, the drive shaft is biased by a spring to a position where the gears are not in contact with each other. When the operator pulls the saw housing toward the drill, the spring is compressed and the gears are engaged, thus allowing the saw to operate. Should the operator lose his or her grip on the housing, the spring biases the drive shaft back to its original position, thereby disengaging the gears.

  • Patent number: 6637101
    Abstract: This invention relates to an improved coaxial cable preparation tool (1) that is used to prepare a coaxial cable terminal end for connector installation. The tool comprises two stages. The first stage, the jacket stripper, is used to trim the cable jacket. The second stage (20), the cable trimmer, is used to trim the remaining center, the outer conductors and the foam insulation of the coaxial cable. The first stage (10) consists of a cup or cylinder (11) with an outer cylindrical wall (12). In addition, it also comprises a blade (13) and a scrap port (14). In addition, the first stage cylinder (11) has a bore (16) extending axially down its center. The diameter of the bore (16) is set to receive a coaxial cable. The second stage consists of a hub (21) (or cutter head), a collet bearing (22) and a body (23). In addition, like the first stage, it also contains blades (13) and scrap ports (14). The scrap ports or debris ports (14) allow trimmed cable media to escape from the bores in the tool.
