Abstract

A plastic disc with a non-cutting edge for use in place of a cutting disc on a power tool. The disc has an inlaid marker, which can be used as a reference point when measuring revolutions per minute (RPM) of the power tool. The disc can be a variety of sizes to suit the appropriate power tool. The tool may be an angle grinder, chopsaw, circular saw, mitre saw, or other type of power tool that may require an RPM test.

RPM DISC
Description;
This invention is for the safe testing of the Revolutions per Minute (RPM) of power tools such as Angle Grinders, Chopsaws, Circular saws, Mitre saws, petrol cut off saws and any power tool that requires an RPM test.
This invention is a plastic disc with a non-cutting rounded edge with an inlaid marker. The non-cutting edge is a safety feature that will eliminate the risk of injury to persons performing an RPM measurement test. The inlaid marker is for is for the purpose of a Laser RPM meter to identify and thus count the revolutions per minute of the tool being tested using this invention.
Presently to test the RPM of power tools a sticker is attached to an actual cut off or grinding disc. This invention replaces the need to use an actual cut off or grinding disc.
