Burr and slag removal
Cutting leaves burrs on the edge and, with plasma or flame, hard slag stuck to the underside. We help you pick the disc or brush that clears it quickly without eating into the part.

Why it matters
Burrs and slag cause rework later: parts that will not stack, coatings that fail at the edge, and sharp edges that hurt people. Taking them off in one controlled pass is faster than chasing them with hand tools.
Light burrs from a laser or punch need a different tool than heavy burrs or slag from plasma and oxy-fuel. The right pick depends on how stuck-on the material is, what you cut, and the machine it runs on.

What we'll ask you
Your machine and brand, the disc size and connection, the material and thickness, how the part was cut, and how aggressive the burr or slag is. For slag brushes we also ask about pin hardness. Skip anything you are not sure of; we will fill the gaps.

Common questions
What is the difference between a burr and slag?
A burr is a thin ridge of displaced metal left by cutting or punching. Slag is hardened, re-solidified material that sticks to the edge, mostly from plasma and oxy-fuel cutting. Slag usually needs a harder, more aggressive tool.
Which pin hardness should I start with?
For most jobs, the first pin hardness (Hardness 1) is enough and protects the edges. Step up only when slag is heavy or very stuck-on. Tell us what you are removing and we will choose.
Can one tool do both burrs and edge rounding?
Often yes, especially with the more aggressive disc levels, but it depends on how large a radius you want. See edge rounding.
