Abstract
A rotary saw having an adjustable depth guide with a handle portion attached thereto is provided. The rotary saw has a housing with a flange projecting outwardly therefrom. The depth guide includes a column with a vertical channel therein. The depth guide is coupled with the housing by slidably receiving the flange in the channel. A transverse bolt in the housing permits a user to prevent movement between the depth guide and the housing and thereby set a cutting depth. A handle portion is removably coupled with the depth guide such that movement between the depth guide and the housing does not alter the relationship between the depth guide and the handle portion.
Claims29
A rotary saw comprising:
- a housing having an outer surface, a top and a bottom, wherein the housing defines an internal cavity, and wherein the housing further includes a first mating portion on the outer surface of the housing adjacent the bottom of the housing;
- a motor at least partially contained in the cavity of the housing for providing rotational output for the rotary saw;
- an adjustable depth guide coupled with the housing, wherein the depth guide includes a column and a guide base, wherein the column has an upper portion, a lower portion, an inner surface, an outer surface and a second mating portion, wherein the guide base is coupled with the lower portion of the column and is in a spaced relationship with the bottom of the housing, wherein the second mating portion is on the inner surface of the column and is slidably coupled with the first mating portion of the housing, whereby the column is slidably movable with respect to the housing, and whereby a user of the rotary saw can selectively move the guide base toward and away from the bottom of the housing;
- and
- a bolt coupled with the housing, wherein the bolt cooperates with the housing to selectively prevent movement of the column with respect to the housing.

A rotary saw comprising:
- a housing defining an internal cavity and having a top, a bottom, an outer surface, and a flange, wherein the flange projects outwardly from the outer surface of the housing;
- a motor at least partially contained in the cavity of the housing for providing rotational output for the rotary saw;
- and
- an adjustable depth guide slidably coupled with the housing to permit a user of the rotary saw to adjust a depth the rotary saw can cut into a workpiece, wherein the depth guide includes a column and a guide base, wherein the column has a lower portion, an inner surface and a channel, wherein the channel is formed in the inner surface of the column, wherein the channel slidably receives the flange of the housing, wherein the guide base is coupled to the lower portion of the column for supporting the rotary saw on a workpiece during use and is a distance away from the bottom of the housing, and whereby a user of the rotary saw can adjust the depth the rotary saw can cut into a workpiece by adjusting the distance the distance between the guide base and the bottom of the housing.

A rotary saw comprising:
- a housing defining an internal cavity and having a top, a bottom, an outer surface, and a flange, wherein the flange projects outwardly from the outer surface of the housing;
- a motor at least partially contained in the cavity of the housing for providing rotational output for the rotary saw;
- a depth guide having a column and a guide base, wherein the column has a lower portion, an inner surface and a channel, wherein the channel is formed in the inner surface of the column and slidably receives the flange of the housing to facilitate sliding coupling of the depth guide to the housing, wherein the guide base is coupled to the lower portion of the column and supports the rotary saw on a workpiece during use;
- and
- a handle portion coupled with the depth guide for gripping by a user during operation of the rotary saw, the handle portion having an inner surface and a lower surface, wherein the inner surface of the handle portion faces the column, wherein the lower surface of the handle portion is adjacent the guide base and is in a spaced relationship therewith, and wherein a user of the rotary saw can selectively move the guide base toward and away from the bottom of the housing without altering the spaced relationship between the guide base and the lower surface of the handle.

A rotary saw comprising:
- a housing defining an internal cavity and having a top and a bottom;
- a motor at least partially contained in the cavity of the housing for providing rotational output for the rotary saw;
- a depth guide slidably coupled with the housing and having a column and a guide base, wherein the column has a lower portion, wherein the guide base is coupled to the lower portion of the column and supports the rotary saw on a workpiece during use, and wherein a user can adjust a cutting depth of the rotary saw by moving the guide base toward and away from the bottom of the housing;
- and
- a handle portion coupled with the depth guide for gripping by a user during operation of the rotary saw, the handle portion having a lower surface, wherein the lower surface is adjacent the guide base and is in a spaced relationship therewith, and wherein a user can adjust the cutting depth without altering the relationship between the guide base and the lower surface of the handle portion, whereby a distance between the handle portion and a workpiece does not change when a user moves the guide base toward and away from the bottom of the housing and adjusts the cutting depth.
