A portable band saw includes a serviceable/replaceable bumper system for allowing the band saw to be easily repaired if damaged from being dropped. An auxiliary handle is adjustably mounted to the band saw and is releasable from its position if subjected to a large force so as to avoid damage to the handle and tool housing. An adjustable guide shoe includes a toolless adjustment. The front and rear section of the band saw are disposed on opposite sides of a polymeric field case. Compression rods are used to isolate compression forces from the polymeric field case. An electric box assembly including a plastic component box is disposed between the field case and a front section of the band saw. A crash guard is mounted adjacent to the field case and includes a sight guide along an edge thereof and a rear blade guard formed integrally therewith.

Portable band saw

An angle grinder is provided including a radial fan assembly. The radial fan assembly is configured to direct exhaust radially outwardly and axially away from a user of the angle grinder. Brush card assemblies for an angle grinder are also provided. The brush card assemblies provide for the securing of brush cards to a field case of the angle grinder by the interface between the field case and brush cards. Additionally, a spindle lock mechanism and a safety mechanism for an angle grinder are provided.

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.

Low profile electric sander

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 saw blade clamping arrangement for a power tool includes a clamp support, a biasing member and an actuation member. The clamp support is interconnected with the drive shaft for reciprocating motion with the drive shaft relative to a housing of the power tool. The clamp support is configured to selectively receive a saw blade of the power tool in various orientations. A release lever is carried by the housing and is manually rotated to move a control member between a first position in which the saw blade is coupled to the drive shaft and a second position in which the saw blade may be displaced from the drive shaft. In at least one of the orientations, the saw blade is positioned offset from the drive shaft and proximate one of the side walls of the tool housing to allow for flush cutting of a work piece.

A reciprocating saw includes a saw blade that is connected to a hand held driver for reciprocating the saw blade to perform a cut. A bit holder and a blade holder is used to provide connection between the saw blade and the handle of the hand held driver. The bit holder includes connecting mechanism for connecting the bit holder to the hand held driver. The blade holder provides a connection between the saw blade and the bit holder. The blade holder includes a holder body and a hex-shaped shank extending rearwardly from the holder body. The shank further includes a first holding mechanism for coupling the holder to the bit holder at the rear end and a second holding mechanism for coupling the saw blade to the holder at the forward end.

Reciprocating saw holder

A powe tool includes a saw blade ejection mechanism for a saw blade clamping arrangement of a power tool. The power tool includes a housing, a drive shaft mounted for reciprocating motion relative to the housing and a saw blade. The clamping arrangement is operative for releasably connecting the saw blade with the drive shaft. The saw blade ejection mechanism includes a mounting member and an elongated plunger. The mounting member is adapted for attachment to the drive shaft. The elongated plunger is connected to the mounting member for movement between a first position to a second position for ejecting the saw blade from the saw blade clamping arrangement.

A reciprocating saw,with a keyless blade clamp,having a slotted-channel,in a clamp body,for receiving a blade,alternatively in first and second, intersecting cutting planes. The blade,may be alternatively oriented in four 90&deg; offset orientations with the blade teeth facing in the same directions as the top, bottom, left and right side of the saw,When the retainer,is in the clamp disengaged position, a blade,may be slidably inserted and removed from the channel,in any of the four 90&deg; offset orientations. A retainer,is located in a track,in the clamp body,and is movable between clamp engaged and disengaged positions. When the blade,is located in the first cutting plane, the retainer,engages the edge,of the blade. When the blade,is in the second cutting plane, the retainer,engages the sidewall,of the blade,A manual operated, spring biased release,is pivotally connected to the clamp body,and is connected to the outer tips,of the retainer,for moving the retainer,between a clamp engaged and a clamp disengaged position.

Clamp

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.
