What Constitutes a Grinder Saw

The efficiency of an angle grinder lies in the quality of grinder saw or the disc which helps in removing excess material or simply cut into pieces. That is achieved by different kinds of discs such as abrasive grinding discs, cut-off discs (diamond blade), grinding stones, wire brush wheels, sanding discs and polishing pads.

The strength of the grinder saw and the motor determines the choice of right grinder for a specific use. Different functions with precision could be achieved by choosing grinding discs which have appropriate backing, coat, and abrasive material.

For paint removal and fiberglass grinding, an open coat with durable fiber backing saw is used. Closed coat saw is made of aluminum oxide and fiber-backed, typically used for fiberglass, wood, and metal sanding. 

Fiber Discs are alumina zirconium mineral-based. Sharp, strong, and versatile, offer supreme debarring, weld grinding and blending, and metal removal. Disc size increases with the corresponding increase in the power.

The geometric setting is done to the grinder parts so that instrument functions best. The circular grinder saw must be tensioned to properly operate because when the saw comes to speed, the rim stretches due to centrifugal force. 

If they are not properly inserted, the saw will not move perfectly. They may move like a sauce pan ride. A saw that is to be run at a higher speed will have to have more tension than one operated at slower speed. Hence while hammering the saw, the RPM to which it is going to be used and the power of the grinder should be well informed.

As every machinery parts, the size of saw also reduces when they are used repeatedly. 

To avoid this, grinder parts include inserted tooth blades. An added advantage is that they allow easy repair as they eliminate the need to regrind the gullets and swage the teeth. Sharpening of this grinder saw can be done by many methods which range from filing by hand to using some specific gadgets for them. Based on the size and sharpness required, one can choose the method they want.

Some of the characteristics of the grinder saw are that the cuts are straight and relatively accurate. There could be some blurs left on the cutting surface by the saw. But most likely they have a good surface finish. Cutting is done by the teeth on the edge of the thin blade.
