Benefits of technology

The patent describes a blade that can be inserted into a drywall without making contact with any utilities behind it. This minimizes the amount of dust generated during the process. The blade has teeth that cut through the outer layer of the drywall to reduce the amount of dust produced. Overall, this results in a more efficient and safe way to install and remove blades from drywalls.

Problems solved by technology

A common problem associated with usage of such drywall cutting tools is that when the blade is inserted into the drywall, the blade may cut or damage utilities located behind the drywall.
For instance, the blade may cut or damage electrical lines, plumbing, or other utilities disposed behind the drywall.
Contact between the blade and the utilities may also place the individual cutting the drywall at risk of injury (e.g. electrical lines, gas lines).
In addition, such contact may also create considerable damage, which may be very costly to fix.
In the case of a hired contractor, the cost of repair may be greater than the profit expected for the original project.
Another problem associated with conventional drywall cutters relates to the dust generated when cutting the drywall.
In particular, conventional drywall cutters tend to generate significant amounts of dust or debris when cutting the drywall.
When the blade travels through the inner chalky layer, it has a propensity to pull chunks of the inner chalky layer out of the drywall sheet, which causes dust to settle in the areas surrounding the drywall.
The cleanup adds unwanted time and expense to the construction project.

Embodiment Construction

[0021]Referring now to the drawings wherein the showings are for purposes of illustrating a preferred embodiment of the present invention only, and not for purposes of limiting the same, FIGS. 1-6 illustrate a drywall cutting blade 10 constructed in accordance with an embodiment of the present invention. Various aspects of the invention are directed toward a blade 10 configured to reduce the amount of dust produced when cutting the drywall 40. Furthermore, other aspects of the invention are directed toward mitigating contact between the blade 10 and utilities which may be disposed behind the drywall 40, such as plumbing and electrical lines.

[0022]The blade 10 is configured for use with a reciprocating saw 12 for cutting drywall 40. As used herein, a reciprocating saw 12 is a tool that is engageable with a cutting instrument (such as a blade 10) to drive the cutting instrument through a cutting cycle. In most cases, the reciprocating saw repeatedly pushes and pulls the blade 10 throu...

Abstract

There is provided a replaceable drywall saw blade capable of reciprocating in-line when mounted to a hand held reciprocating power saw. The blade includes a generally planar body member having a generally linear top edge and a generally parallel opposed bottom edge. The blade further includes a generally linear upper piercing edge angularly offset downwardly from the top edge. The blade additionally includes a generally linear lower piercing edge angularly offset upwardly from the bottom edge. The upper piercing edge and lower piercing edge intersect to form a forward point on said blade. A mounting aperture is also formed on the blade for releasably securing the blade to the hand held reciprocating power saw.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a continuation of U.S. patent application Ser.
