A slide hammer tool including a shaft having first and second opposing ends, a handle slidably coupled to the shaft, and a slide hammer weight assembly removable coupled to the handle via threaded fasteners. The slide hammer weight assembly including a number of slide hammer weights coupled together.

The present invention is an adjustable weight dead blow hammer comprising a hollow head filled with an acceptable fill material. A handle is connected to the head wherein the handle has a hollow chamber that traversers the length of the handle and has an opening into the head. The weight of the hammer head may be adjusted by moving the fill material between the head and the hollow chamber in the handle. Adjustment may be accomplished by a corkscrew device which is disposed within the hollow chamber and having a screw tip at the opening and c screw head on an outside portion of a bottom end of the handle. The corkscrew device within the hollow chamber moves the fill material between the head and the handle. More fill material in the head increases the force of impact, and less fill material in the head decreases the force of impact.

The slide hammer weight assembly including a number of slide hammer weights coupled together.

A hammer head with an internal cavity including weights that are sized to restrict the weights from escaping from a crack in the hammer or are easily collected and accounted for should the hammer separate to ensure foreign objects and debris do not contaminate sensitive work spaces. The weights are shaped to allow the weights to longitudinally move in the internal cavity. The weights may take the form of a number of different shapes.

A power tool includes a motor, a drive mechanism, and an impact mechanism. The drive mechanism is capable of driving a tip functional element to rotate about an output axis. The impact mechanism is capable of abutting against the tip functional element and capable of driving the tip functional element. The impact mechanism includes an impact rod, an impact power piece, and an impact block. The impact rod abuts against the tip functional element. The impact power piece is used for generating impact power. The impact block is disposed between the impact rod and the impact power piece, capable of forming a gas space with the impact power piece, and capable of reciprocating when impacted by the impact power generated by the impact power piece. A minimum length of the gas space in a direction of the output axis is less than or equal to 13 mm.

Striking tools are disclosed that include an aluminum head. Striking surfaces may be securely attached to the head by a bushing or other means. In this way, light weight striking tools may be made with greater durability.

An impact tool includes a casing (13) supporting a tip tool (12), a piston (41) provided in the casing (13), an electric motor (11) provided in the casing (13), a motion converting mechanism (45) provided in the casing (13), and a vibration reducing mechanism (47) provided in the casing (13). The vibration reducing mechanism (47) has a supporting member, which is swingable with using a fixing position (J) as a supporting point and a weight (49) attached to a free end side of the supporting member. In a plane including a center line (C), the gravity center (H) of the weight (49) and the gravity center (G) of the casing (13) are disposed at mutually different locations, and the fixing position (J) is disposed on the side of the gravity center (G) relative to the center line (C).

A chiselling hand-held power tool having a tool holder for holding a tool on a working axis, an electric motor, and a striking mechanism. The striking mechanism has an excitation piston coupled to the motor, a striker guided on the working axis and a pneumatic chamber closed by the excitation piston and the striker for coupling a movement of the striker to the excitation piston. The rotational speed of the electric motor corresponds to at least 20 times the striking rate of the striking mechanism.

A percussion tool, for performing a chiseling operation on a workpiece with a chisel, comprises a housing including a front side, and rear side, and opposite lateral sides extending between the front and rear sides, a first handle coupled to a first of the lateral sides of the housing, a second handle coupled to a second of the lateral sides of the housing, the first and second handles oriented coaxially along a handle axis, an electric motor positioned within the housing, a percussion mechanism driven by the motor and including a striker supported for reciprocation relative to the housing along a striker axis, and a light source that produces light to illuminate the workpiece. The chisel is configured to deliver repeated axial impacts to the workpiece in response to receiving repeated axial impacts from the striker.
