Abstract

A chop saw including a base, a rotatable table rotatably disposed on said base, and a saw unit pivotably connected to the table. The saw unit includes a blade, a motor for driving the blade, and a housing for covering the motor. The saw unit is movable downwardly towards the table in order to cuttingly engage a workpiece. In addition, the chop saw includes a battery connected to said motor. Preferably, the battery is attached to the housing.

Claims

1-20. -20 (canceled).

21. :

A chop saw comprising;

a base;

a saw unit including a motor and a blade driven by the motor;

a pivot hinge connecting said saw unit to said base, the pivot hinge allowing the saw unit to be movable between a first upper position away from the base and a second lower position towards the base to cuttingly engage a workpiece disposed on the base; and

a battery electrically connected to the motor;

wherein said battery is attachable to said saw unit.

22. :

The chop saw of claim 21, wherein the saw unit further comprises a housing covering the motor.

23. :

The chop saw of claim 22, wherein the battery is attached to said housing.

24. :

The chop saw of claim 21, wherein the base comprises a rotatable table rotatably disposed on said base.

25. :

The chop saw of claim 24, wherein the table rotates about a first axis.

26. :

The chop saw of claim 24, wherein the saw unit is pivotally connected to the table.

27. :

The chop saw of claim 26, wherein the saw unit rotates about a bevel axis.

28. :

The chop saw of claim 27, wherein the table rotates about a first axis.

29. :

The chop saw of claim 28, wherein the bevel axis is substantially perpendicular to the first axis.

30. :

The chop saw of claim 21, wherein the saw unit rotates about a bevel axis.

31. :

The chop saw of claim 21, wherein the battery is rechargeable.

32. :

The chop saw of claim 21, wherein the battery has a battery chemistry selected from the group consisting of nickel cadmium, nickel metal hydride, lithium and lead-acid.
