Finishing oxy-fuel cut parts

Heavy slag, oxide and edges after flame cutting

Oxy-fuel cutting is often used on thicker steel and can leave heavy, stuck-on slag. A harder pin brush and a double row may be needed, followed by edge work and oxide removal.

What to use

Problem	Tool	Notes
Hardened slag	Slag removal brush	Start at Hardness 1; step up to Hardness 3 or 4 for heavy slag
More slag per pass	Double row brush	More pins working at once
Burrs and sharp edges	Deburring disc	Choose a coarse and aggressive abrasive for heavy work
Scale and oxide	Oxide brush or wheel	Depends on your machine

Protecting the part

Lower hardness levels use flexible pins at low pressure to protect edges. Tell us the thickness and material so we can match the hardness to the job.

What we need to recommend tools

Your machine and brand, tool size and connection, thickness, material and how stuck-on the slag is.

Common questions

What hardness for heavy oxy-fuel slag?

Start at Hardness 1 if you can. For slag that will not let go, Hardness 3 or 4 may be needed. Tell us what you are removing.

Single or double row for flame-cut parts?

Double row puts more pins to work at once, which helps on heavier slag.

Do I still need to round the edges?

Often yes, after slag is off. A deburring disc finishes the edge.
