Definitions for "Burrs"
Tiny, almost microscopic shards of die steel protruding into the die aperture (opening), usually from either the entry or exit edge of the bearing. They are typically formed during the manufacture of the die but can also be formed by striking the die opening with a hammer, dies bumping together during handling or other abnormal impacts to the die face.
Jagged edges or protuberances on the surface of metal created during stamping or other industrial applications.
A thin ridge of roughness left by a cutting operation such as trimming, shearing, sawing, and machining.
These are the sharp edges that stick out from your part after drilling or cutting. Burrs create two major problems. They are unsafe and they do not allow your parts to fit together properly. You can use a file or sand paper to remove them.
Metal protrusions on metal parts due to dull tooling, improperly punched or cut parts of the belt.
