Abstract

A circular blade 3 attached to a shaft 1, said shaft 1 connecting to the chuck of a hand drill, said hand drill being used to drive a gear mechanism that drives the circular blade 3. A depth guide (8) and blade cover (7) may be provided. A handle may be attached in two positions (4,5) to guide the circular blade 3.

Description

DESCRIPTION
The invention relates to a power tool accessory capable of attaching to a rotary power source such as a hand drill. More particularly this invention relates to a disc cutter powered by a gear mechanism powered by a hand drill.
Disc cutters are well known they come in the form of circular saw for cutting wood or an angle grinder for cutting masonry. This could mean for a person who requires the use of small disc cutter for channelling walls and cutting floorboards to run cables and pipe work, power tools surplus to their requirements.
An object of this invention is to provide a disc cutter that can be powered by any hand drill and has blades for cutting various materials.
Accordingly, this invention provides a disc cutter including a shaft attachable to any hand drill chuck that drives a housed gear mechanism that in turn drives a circular blade. The cutter includes a blade cover which can rotate about the blade for safety and versatile cutting of known design a handle to be attached in either of two places of known design and a depth guide to assist cutting. When operated one hand is used to operate the drill and one to guide the cutter.
The cutter is made from hard plastics and metals and uses a blade changing system of known design. There are various blades suited to cutting different materials.
A preferred embodiment of the invention will now be described with reference to the accompanying drawings in which: Figure 1 shows a side view of the cutter.
Figure 2 shows another side view of the cutter.
As shown in figure 1 the cutter comprises a shaft 1 that is connected to the chuck of a hand drill to provide rotation to drive the gear mechanism of known design enclosed in housing 2.The gear mechanism can then rotate the blade 3 to use for cutting.
The bearing 4 shows an attachable handle. Bearing 5 shows the two places it can be attached. Bearing 6 shows a button, part of the blade changing system of known design. Figure 2 shows a blade cover 7 this covers about 50% of the blade and can be rotated around the blade by known design. Bearing X shows the cutting depth guide it is attached to blade cover by a hinge of known design at bearing 9. It can be adjusted by the compression of an adjustable nut and bolt bearing 1 0.Bearing I I shows measurements labelled on the depth guide for cutting requirements.
