Properly learning how to operate an angle grinder might take some time. To be more specific, there are numerous different tasks that may be completed with an angle grinder, and each requires a unique set of skills and methods. You’ll probably find out along the line that the angle grinder’s stock disc isn’t up to snuff for your particular job. Therefore, you should make time to research the many options now accessible to pros and do-it-yourselfers. The seven most common discs for angle grinders and their respective functions are covered in this article. This manual will also explain the materials used to produce several of these discs, so you can determine whether they are appropriate for the material you want to use them on.
Types of Cutting Discs
The grinding wheel is the most basic and recognisable kind of disc for an angle grinder.
These wheels are typically disc-shaped and have a ribbed edge designed to quickly smooth off sharp metal corners. As a result, these wheels find widespread use in metal manufacturing processes that call for the finishing of newly cut edges. Angle grinders with grinding wheels attached are useful for finishing off new welds. However, it is imperative that appropriate safety measures be implemented in handling such a disc. This is because its metal composition results in very fast metal-on-metal contact. Also, a large number of sparks might fly from the site of contact.
POP A DISK
When compared to other methods, grinding wheels are seen as quite “blunt.” Because of this, they aren’t often employed for tasks where the finished product will be handled by a human. Alternatively, a fabricator could remove a disc with flaps. In the metalworking world, they are like having access to fine sandpaper. Flap discs, when used correctly, provide for increased accuracy for removing metal burrs, chamfering edges, and rounding off sharp corners. Flap discs may even remove cutting and manufacturing blemishes with enough pressure. Therefore, they are crucial for metalworkers whose projects are routinely worked on by others. There is a risk of serious burns if you contact one of these blades immediately after usage.
You probably already know that angle grinders may be used to make quick work of cutting through both flat and circular metal material. It goes without saying that you’ll need to attach a cut-off wheel to your angle grinder in order to achieve this. These discs’ slim design and tapered edge make them ideal for cutting through forged metal. As long as the wheel is wide enough, they may be used effectively to cut through a variety of materials, including bolts, plate metal, rebar, and more. This is due to the increased flexing of narrower cut-off wheels during operation. As a result, they are unsteady and often break (or even shatter) while cutting through heavy metal sheets. A thicker cut-off wheel should be utilised instead.
“Angle grinders may be utilised to do various kinds of crucial abrasion chores provided you have the correct discs on hand. Any competent fabricator needs a disc like a wire wheel because it effectively removes paint and corrosion from metal. Their sets of metal wire fibres, organised in straight or tangled bunches to optimise abrasion potential, are the key to this feat. However, it’s important to remember that wire wheels come in a wide variety of quality levels. That is to say, if you can help it, steer clear of the inexpensive wire wheels. These discs deteriorate rapidly, releasing their metal wires to scatter around the room. If you’re not wearing protective gear while operating a wire wheel, you and your coworkers might get hurt.
“A wire wheel can strip paint quite efficiently, but this efficiency does not come cheap. In particular, after the paint has been stripped off, the metal surface is often marred by wire wheels. It’s important to remember to carry a strip disc to the construction site in order to prevent it from happening. The poly-fiber substance used to make these discs is soft enough to be safe for most metal surfaces, yet tough enough to remove paint, glue, and epoxy. This disc is also vital for removing coatings and adhesives from fibreglass and wood. If you don’t, you’ll discover that your wire wheel destroys the finish of either substance.
DISC MADE OF DIAMOND
“Diamond discs may take many shapes. However, the vast majority of diamond discs available today are cutters. Diamond discs are unparalleled in their ability to cut through extra-dense metal stock, and they can do it with ease because of the diamond abrasive shards impregnating their edges. While diamond discs certainly have their uses, they also tend to be rather pricey. Therefore, they should be used only for cutting tasks that genuinely need them.
CERAMIC SANDING DISC
“Despite their prolonged service life, ceramic sanding discs are not nearly as widespread in the professional industry. Ceramic sanding discs are versatile and may replace flap discs for a wide variety of sanding tasks. As a result of their ceramic structure, however, they are able to do these tasks without danger of overheating. Ceramic sanding discs are not only more long-lasting than metal ones, but they also have a better sanding capacity.
Safety Cutting Discs
When using a cutting tool, such as a cut-off wheel or a grinding disc, it is imperative that you observe all applicable safety rules. All discs and wheels include the relevant industrial safety pictograms. If the cutting discs have any apparent damage such as cracks, chips, or evidence of bending or twisting, they should be replaced immediately. The useful life of cut-off wheels is indicated by a date stamped on the disc’s metal hub, after which they must be replaced.
- Before you start using the cut-off wheel or the grinding wheel, make sure there are no cracks or chips.
- Watch that your tool speed doesn’t go over the recommended limit for your cut-off or grinding wheel.
- If you need to change the wheels or won’t be using the tool for a while, unplug it.
- Maintain a clean and safe working environment.
- Make sure the item being worked on is safe.
- Put on the right kind of PPE at all times (PPE)
In no circumstances can the use limits be broken, such as when using for wet grinding.
- If it’s broken, don’t use it.
- In no way may the cutting disc be used as a grinding tool.
