Choose an angle grinder

Ideal for quickly cutting large numbers of materials, the grinder is not a tool to buy on a whim. It consists of a disc, a motor and an axis. Depending on the type of work, the power and the disk will not be the same.

Choose an angle grinder: materials

The choice of power.

For deburring work angle grinders from 600 to 1000W are sufficient. To cut metal you will need a power of 1000 to 1300W. For site work, prefer a 2000W grinder. For heavy masonry work two-handed grinders are recommended because they are very powerful and ensure a perfect grip.

The choice of the disc

To deburr:

For metals: aluminum, cast iron, stainless steel or steel, choose a thickness from 6 to 6.5. For materials: stone, cement; concrete, choose a thickness of 6.5 to 7.

To cut:

For metals, a thickness of 2.5 to 3.2 mm. For materials, stone, cement, concrete, cast iron choose a thickness of 2.5 to 3.2 mm. For building materials: concrete, reinforced concrete, breeze block, granite choose a blue disc with a diameter of 100 mm. For building materials with limited cutting series, choose a yellow disc with a diameter of 115 mm. For fragile materials such as marble, earthenware or travertine, use a green disc with a diameter of 125 or 150 mm. For abrasive materials such as brick or sandstone, use a red disc with a diameter of 180 mm. For very abrasive materials, such as bitumen or asphalt, choose a black disk with a diameter of 230.mm

To sand and even:

It is necessary to use a semi rigid disk on plate with a grain between 36-80.

Handyman Sunday does not recommend multifunction models and low-end, mostly dangerous and not allowing a specific job. We recommend that novices give priority to progressive start models with a variable speed drive.
