In a cordless power tool system, high temperature gases created in a battery pack by the battery cells during a charging or discharging operation can be routed into a housing of one of an attached power tool or charger to reduce the temperature of the gases, prior to venting the gases externally. In an example, a battery pack has at least one vent hole for relieving pressure and a movable device covering the vent hole and configured to expose the vent hole upon a pressure set-point within the pack housing being exceeded. In another example, the pack housing includes a thin-walled section designed to break if pressure within the pack housing exceeds a given pressure setpoint. In a further example, the pack housing includes a baffle having an S-shaped cross-section for providing a vent path for gases and for preventing external fluids from entering the pack housing.

An electrically powered belt sander comprising a housing, a dust flow path defined by the housing, a motor mounted in the housing at a first location and having an output shaft, a fan connectable to the motor output shaft and rotateably mounted in the housing at a second location a distance from the motor output shaft, a belt connectable between the motor output shaft and the fan whereby the rotation of the motor output shaft drives the rotation of the fan, and a damper located in the dust flow path and operable for blocking the dust flow path.

A power tool is a 'low profile' power tool, that is the overall height of the power tool is sufficiently small that a user can grasp the top of the power tool with the user's hand and the hand will be positioned relative close to the bottom of the power tool compared with existing power tools. The low profile power tool uses a low profile motor having a diameter to lamination height ratio of at least 2:1. In an aspect of the invention, the motor is an electronically commutated 'pancake' style motor. In an aspect of the invention, the power tool is a random orbital sander or an orbital sander having a motor that provides at least 40 watts of power. In an aspect of the invention, the sander has a mechanical brake that brakes the orbital mechanism and the motor is dynamically braked.

A frame for a portable power sander, the frame convertible into a stand for supporting the power sander in a stationary orientation wherein the abrasive belt is accessible, said frame comprising: a base; a leg connectable to the base, and a fence assembly connectable to the base.

A hand-held power saw (,) having a housing (,) which includes a blade storage chamber (,) and a retaining member (,) for holding at least one spare saw blade (,) within the storage chamber. In one embodiment the retaining member comprises a rubber component having a pair of arms (,). Each arm has a groove (,) formed therein which holds a ball bearing (,). The ball bearings are biased into contact with one another once the retaining member is assembled into a housing portion of the tool within the storage chamber. When a spare saw blade is inserted into the storage chamber a portion thereof is urged between the ball bearings. The resiliency of the rubber arms causes the ball bearings to grasp the spare saw blade and retain it within the storage chamber. The opposite end of the blade engages a foam-like member (,) held within a recess (,c) at the opposite end of the storage chamber which prevents the blade from rattling within the chamber. In alternative embodiments a pivotably mounted retaining member (,) is disclosed which operates in cooperation with an independent clip (,) to retain a spare saw blade in the storage compartment. The various embodiments enable a spare saw blade to be accessed without any external tools and without any separate cover members needing to be removed from the power tool housing.
