How long does a grinding wheel last?

within 2 yearsIt 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.

What can I use to grind down metal?

Use an electric grinder to be fast and efficient. Electric grinders easily cut and grind through metal. These types of grinders work best on large jobs or making straight cuts since they are bigger and cannot easily move with finesse. Electric grinders do not work well in tight spaces or curves.

How long should a diamond blade last?

around 12 hoursA low quality diamond blade under perfect conditions can last around 12 hours, but with improper technique or the wrong materials, this could be reduced by half or more. On the other hand, some high quality diamond blades under standard working conditions have been known to have a life of over 120 cutting hours.

Can aluminum create a spark?

How do I choose a grinding wheel?

For a broad area of contact, use a wheel with coarser grit and softer grade. This ensures a free, cool cutting action under the heavier load imposed by the size of the surface to be ground. Smaller areas of grinding contact require wheels with finer grits and harder grades to withstand the greater unit pressure.

Will diamond blade cut aluminum?

You should be able to use a carbide-tipped abrasive cutoff wheel for non-ferrous metals like brass, aluminum, copper or lead. … Instead, we recommend using a diamond blade that’s rated to cut ferrous metal. These will last much longer, cut faster and cleaner, and wear down much slower than abrasive discs.

How do I know if my diamond blade is dull?
