What speed should a deburring
tool be used at?

Shop for Deburring Tools

If you choose to use a machine (lathe, pillar drill, jig borer) to deburr the workpiece, the correct speed and feed rate must be selected.

Feed rate

Direction of feed, tool tip Feed rate is the speed at which the cutting tool travels across the workpiece being machined. It can also be the speed at which the material is fed to the cutting tool.

The feed rate is measured in SFM (surface feet per minute), this is how quickly the tool or material moves over the bed surface of the machine (lathe, pillar drill).

Speed

How many full revolutions per minute is made The speed of a cutting tool is measured in RPM (revolutions per minute). This is the rate at which the workpiece or tool rotates.
As the speed of a cutting tool or workpiece is equal to the number of revolutions it makes in one minute, it is measured in RPM (revolutions per minute).

Finding the correct feed rate and speed

Cutting speed formulas To obtain the correct RPM (revolutions per minute) or SFM (surface feet per minute) for deburring, use this formula.
Below is an approximate guide to the feed rates of commonly used materials which may need deburring.
Material to be machined 

Aluminium

Brass / bronze

Cast iron (soft)

Cast iron (medium)

Plastics

Mild steel

 Stainless steel

Soft wood

Hard wood

SFM (surface feet per minute)

150-250

75-125

50-100

100-250

70-100

When cutting, use a slower speed and feed rate for better results!
