A reciprocating shaft assembly in a reciprocating saw moves in a reciprocal motion and drives a saw blade via a blade holder. At least one bore is formed in an end of the reciprocating shaft assembly opposite the blade holder. A pin fixed to the saw passes through the bore and acts as a bearing to support the reciprocating shaft assembly in its reciprocating motion.

A pneumatic compressor capable of supplying compressed gas to a pneumatic tool. The compressor can be powered alternatively by either a battery or an AC power source. The compressor comprises a permanent magnet DC electric motor and circuitry for converting the AC power source to DC power. The compressor includes a receptacle for accommodating one or more of a plurality of batteries and includes circuitry for using batteries having different voltages. The AC power source may also be used to charge a battery connected to the compressor.

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 &#x201c;release&#x201d; position. When the closure member is in the &#x201c;release&#x201d; position, the battery can be removed from the power tool. A method of releasably securing a battery to a power tool is also disclosed.

A counterweight in a reciprocating saw counterbalances a reciprocating shaft assembly adapted to hold a saw blade. The counterweight is supported for reciprocating motion by slides which ride within slots formed in a housing adapted to hold the reciprocating mechanism.

A portable pneumatic fastening tool has an onboard compressor assembly to alleviate the need for an external air compressor. The onboard compressor assembly includes a motor and a compressor mounted to the tool body. The motor can be powered by a detachable battery mounted to a cover for covering the onboard compressor assembly. A portable pneumatic fastening tool may also be powered by a portable compressor assembly which can be borne by the user.

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 &ldquo;lock&rdquo; 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 &ldquo;lock&rdquo; position to a &ldquo;release&rdquo; position. When the closure member is in the &ldquo;release&rdquo; position, the battery can be removed from the power tool. A method of releasably securing a battery to a power tool is also disclosed.

A reciprocating power tool includes a motor operatively connected with a drive assembly for driving a reciprocating shaft, on which a working tool is supported. The reciprocating power tool includes a base so that the tool may stand upright when resting upon the base without the use of external supports. A counterweight positioned inside of the drive housing minimizes vibration. The motor is preferably positioned so that its rotational axis is angled with respect to a longitudinal axis of the reciprocating shaft. This configuration of the motor produces a compact configuration for a reciprocating power tool and helps the tool stand upright upon the base of the tool. A battery may be provided in a cordless embodiment and is advantageously positioned for balancing the tool.

A cordless router motor unit has a metal barrel and a plastic battery housing. A DC motor is housed inside of the barrel and drives an output shaft and up to a &frac12;&Prime; collet chuck. The battery housing holds a power switch and is fastened to the barrel. A battery is releasably attached to the battery housing through a sliding engagement in a direction normal to the longitudinal axis of the motor unit. When the battery is in its locked position relative to the battery housing, the center of gravity of the battery is balanced over the output shaft. The power switch is positioned radially from the DC motor and below the battery so that the router motor unit has a low center of gravity. The battery provides at least 18V and the maximum power output of the DC motor is at least &frac58; hp. The barrel can be sized to engage with a router base which also engages with a corded router motor unit.

An arrangement of frictional gripping zones on the handle of a power tool is disclosed. The power tool has a main body portion and a handle portion depending from the main body portion. The handle portion includes a first side region, a second side region opposite the first side region, a rear region connecting the first and second side regions along a rear of the handle portion, and a front region connecting the first and second side regions along a front of the handle portion. A plurality of alternating first and second gripping zones extend longitudinally along each of the first and second side regions of the handle portion. The first gripping zones are made the first gripping zones being made from a first material and the second gripping zones are made from a second material different from the first material. Preferably, the material of the second gripping zones have a hardness greater than the material of the first gripping zones. Furthermore, a third gripping zone is made from the second material and extends longitudinally along substantially the entire front and rear regions of the tool handle. The first gripping zones are preferably sized and configured to correspond to the contour of the power tool handle to provide the user with an efficient frictional gripping when operating the power tool.
