To achieve safe, optimal performance of any wire or abrasive product, think S.P.O.T.
S—Speed and Size. Choose an appropriately sized product for the tool, and use the manufacturer’s recommended guard. Be sure the maximum safe RPM marked on the wire or abrasive wheel is greater than or equal to the maximum operating RPM on the tool. When selecting high-performance ceramic abrasives, pay attention to tool speed. Tools with lower power can’t maintain the required speed and therefore don’t provide the full advantages of these high-performance, higher-priced products.
P—Pressure. When operating wire brushes, you shouldn’t have to push harder because the tips should be doing the work. Applying excessive pressure to the brush prevents the tips from hitting the surface, so the sides of the wire begin “wiping” the surface. This reduces cleaning action and increases wire loss because of stress. If a power brush is not performing to expectation, consider changing the knot, increasing the wire gauge, or shortening the trim length. A common complaint about wire brushes is wire loss, and the main cause, in many cases, is improper use or excessive pressure.
When you are using an abrasive, increasing pressure slows tool speed and significantly increases friction and heat. Heat and pressure are the enemies of any abrasive product. Use even, consistent pressure and motion to minimize heat discoloration and maximize performance.
O—Orientation. Wheel brushes are designed for use perpendicular to the work surface. This positions the wire tips for optimum performance and reduces lateral stress on the wire, preventing wire loss, poor performance, and short brush life. Bonded abrasive cutting wheels are also designed for use perpendicular (90 degrees) to the work surface for best performance and longevity.
Grinding wheels and flap discs are designed for use at 5 to 35 degrees in general. When selecting a flap disc, choose Type 27 for finishing and applications that require lower grinding angles—5 to 15 degrees. Choose Type 29 for more aggressive, higher angle grinding—15 to 35 degrees.
T—Time. All products are designed to be moved across the work surface. When you are using an abrasive product, do not dwell in one spot as it will lead to pitting, gouging, increased heat, and reduced surface finish.
Knowing what your product options are and understanding their intended uses are important parts of getting the best results from abrasives and wire brushes. Always follow best practices to extend product life, improve operator safety, and increase productivity and efficiency. Doing so can help you complete jobs faster, saving time and money for a better bottom line.
No matter the tool, inspect the abrasive or wire brush each time it’s used for any signs of damage or wear. Replace as necessary.
