You can buy very inexpensive angle grinder tool, but for frequent use or for demanding jobs like cutting stucco or cement, I’d recommend spending a little more for a grinder with a more powerful motor. Outfitted with a grinding wheel, an angle grinder is a great tool for restoring edges on rough-and-tumble tools like hoes, shovels and ice scrapers or for the initial grinding of axes, hatchets and lawn mower blades. Finally, with the grinder off, rest the grinding wheel against the blade and adjust the angle of the grinder to match the blade’s bevel.

The secret to successfully using an angle grinder is choosing the right type of cutting disc. Consider how much wood you want to remove and how fast to define the correct cutting disc for your needs. The angle grinder size is determined by the size of the disc, not the length of the tool itself.
If you need to use the grinder for more than an hour, it may be better to invest in a corded angle grinder. The rapidly rotating disc on an angle grinder doesn’t just smooth, polish, and grind away metal, it can also be used for cutting through metal. Equip the angle grinder with an abrasive grinding disc and ensure that the blade of the tool is properly secured in a vise so that you can focus on controlling and steadying the movement of the grinder.
An angle grinder is a handheld power tool that can be used for a variety of metal fabrication jobs that include cutting, grinding, deburring, finishing and polishing. An angle grinder tool with the right disc can replace numerous tools and make the most tedious, labour intensive jobs quicker and easier. Whether you are preparing carbon steel for painting or finishing a weld seam , grinding wheels and flap discs are essential accessories for the angle grinder.
how long use angle grinder Related Question:
How long do angle grinder discs last?
1 – Cutting and Grinding Discs Have Expiry Dates. Usually expressed as a month and year, such as 03/2018, these expiry dates are printed to comply with the manufacturing regulation, EN12413:2007+A1. This date is generally printed on the centre ring and is at a maximum three years from the manufacture of the disc.
How do you maintain an angle grinder?
Daily care Keep your equipment clean. After each use of the grinder, disconnect power and brush or wipe off dust and sludge (if grinding wet or using a built-in misting system). Tip back the grinder, remove tooling and wipe off the heads. Inspect plates and shroud, make sure screws and bolts are in place and tightened.
Can an angle grinder overheat?
It also could result from excessive sparks from the brushes which can cause the commutator to overheat, transferring the heat to the armature. When the armature becomes too hot, the insulation on the windings can break down and cause the armature to ground out.
When should I replace my angle grinder disc?
Always replace a cutting disc if it shows any signs of damage. This includes, but is not limited to visible cracks and chips or any signs of bending or twists to the wheel. Cut off wheels should be replaced when they hit their expiration date. This can be found imprinted on the metal center of the disc.
Why do angle grinder discs have an expiry date?
The reason these discs have an expiry date is due to the resin used in the manufacturing process. The resin is used to bond the abrasive, and over time, this resin will absorb moisture, leading to deterioration in the cutting or grinding disc.
Do cut off wheels expire?
Cut-off wheels and grinding wheels should not be used past their expiration dates, and that’s if they’ve been properly stored and handled. Mishandling or storing discs in certain conditions might lead discs to be discarded earlier.
Are angle grinders safe?
Angle grinders can cut through stone, concrete, metal and other hard materials, so they have no trouble cutting through human flesh and bones. Contact with the wheel while in operation can have serious consequences, with deep cuts and even amputations.
Why does my angle grinder get hot?
The angle grinder may be low on grease or may have outside elements in the existing grease. Grease is meant to allow the internally moving parts to function with as little resistance as possible. When there’s a lot of strain on the grinder (resistance), it will get hot.
Why is my Makita grinder smoking?
The carbon brushes ride on the commutator, supplying electricity to the motor. As the carbon brushes wear down, they will produce more sparking. This can cause a heavy carbon build up between the brushes and the commutator, resulting in smoke from the grinder.
Why is my angle grinder sparking?
If the brushes become worn, wear unevenly, suffer damage or have a heavy build up of dirt and debris, they can cause excessive sparking. To check the brushes to see if they require replacement, remove the screws securing carbon brush cover on the back of the angle grinder and take off the cover.
How long does a grinding wheel last?
It has always been Saint-Gobain’s recommendation that Resinoid Bonded grinding wheels be used up within 2 years from the date of manufacture. This recommendation assumes that Resinoid Bonded grinding wheels have been stored under ideal storage conditions.
How do I know if my grinding wheel needs dressing?
When the sharpness of grinding wheel becomes dull because of glazing and loading, dulled grains and chips are removed (crushed or fallen) with a proper dressing tool to make sharp cutting edges and simultaneously, make recesses for chips by properly extruding to grain cutting edges.
Is it OK to use a cut-off wheel as a grinder wheel?
While die grinders may look similar to cut-off tools, they are not. They are unguarded tools without flanges and should NEVER be used with cut-off wheels. It is simple to remember: if the tool does not have a guard, do not use a cut-off wheel.
Why do grinding discs explode?
Grinding operations generate tremendous amounts of heat. This heat causes expansion and if foreign materials are embedded in the stone then the differential rate of thermal expansion between the two materials can cause a wheel to shatter.
What is cutting disc?
Often cutting discs, also known as cut-off wheels, are made from a solid abrasive disc. These discs are often used for cutting metal; they are composed of an abrasive mix of grit and adhesive that is formed into a thin, rigid disc with fiber webbing running through it for strength.
