HSS burr
Applications recommendations:
1. HSS burrs, thanks to their special tooth geometry and high
production quality, partricularly suitable for deburring, chamfering,
cast-iron fettling and processing aluminium. They can also be used
cost-effectively with low-power machines in the low turning rate
range.
2. HSS burrs should be used with low-rev machines,
compared to hard-metal burrs.
3. They are not to available for applications where there are
high rev rates.
4. The toughness of high-speed steel (HSS)
gives greater stability to the tooth cutting.
