Choosing between soft, medium, and hard bonds.
Soft Bond (Yellow) ¨C The metallic powder in the segment wears away quickly releasing dull diamond crystals exposing new abrasive crystals to cut efficiently. Best used on hard surfaces.
Medium Bond (Red) ¨C A metal bond strength right between that of soft and hard bonds.
Hard Bond (Black) ¨C The bond of the metallic powder in the segment wears away slowly and prevents premature wear against soft, abrasive surfaces.
