Abstract
A saw includes a housing, a motor, a saw blade, a base plate, and an alignment guide. The motor is at least partially provided in the housing. The saw blade is driven by the motor and defines a cutting plane. The base plate supports the housing. The alignment guide is attached to the base plate and has a laser, a scale, and an indicator. The laser is selectively rotatable and projects a laser beam in a laser plane about a first axis. The scale is positioned about the first axis and has a plurality of first graduations. The indicator is aligned with the scale and indicates a horizontal offset distance between the cutting plane and the laser plane along the base plate.
Claims27
A saw comprising:
- a. a housing;
- b. a motor at least partially provided in the housing;
- c. a saw blade driven by the motor and defining a cutting plane;
- d. a base plate supporting the housing;
- and
- e. an alignment guide attached to the base plate and having:
- i. a selectively rotatable laser projecting a laser beam in a laser plane about a first axis;
- ii. a scale positioned about the first axis having a plurality of first graduations;
- and
- iii. an indicator aligned with the scale, wherein the indicator indicates a horizontal offset distance between the cutting plane and the laser plane along the base plate.
A circular saw comprising:
- a. a housing;
- b. a motor at least partially disposed within the housing;
- c. a saw blade driven by the motor and defining a cutting plane;
- d. a base plate supporting the housing;
- and
- e. an alignment guide attached to the base plate and having:
- i. a selectively rotatable laser projecting a laser beam in a laser plane about a first axis, wherein the vertical distance between the first axis and the base plate is fixed, and wherein the first axis is substantially parallel to the cutting plane;
- ii. a scale positioned about the first axis having a plurality of first graduations;
- and
- iii. an indicator aligned with the scale, wherein the indicator indicates a horizontal offset distance between the cutting plane and the laser plane along the base plate.
A circular saw comprising:
- a. a housing;
- b. a motor at least partially provided in the housing;
- c. a saw blade driven by the motor and defining a cutting plane;
- d. a base plate supporting the housing, wherein the housing is rotatable about a first axis;
- and
- e. an alignment guide attached to the base plate and having:
- i. a selectively rotatable laser projecting a laser beam in a laser plane about a second axis, wherein the vertical distance between the second axis and the base plate is fixed, and wherein the second axis is substantially parallel to the cutting plane;
- ii. a scale positioned about the second axis having a plurality of first graduations;
- and
- iii. an indicator aligned with the scale, wherein the indicator indicates a horizontal offset distance between the cutting plane and the laser plane along the base plate.
