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.
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
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.
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.
