A grinding wheel is a precision tool with thousands of cutting points on its surface abrasive grains that are held in place by a bond matrix hence these are known as bonded abrasives and separated by pores.. these pores are hollow spaces between abrasive grains and the bond , which help with the clearance of discarded metal chips in the grinding process.
