Extensive testing in a variety of machining applications has shown that SAF 2507® bars provided better machinability than the nearest competitor material with 23% better tool life and overall savings on all machined components:
Sandvik Coromant inserts and tool holders were used for all tests carried out.
To compare the machinability of SAF 2507® and material from the closest competitor.

The grade provided better chip-breaking at both low and high feed rates compared to the competitor material and a short helix form was achieved. Short chips enable a better cutting operation, longer tool life and less chip clearance time on the machining tool.
SAF 2507® produced 168 holes against 135 holes for the competitor material and consumed 18% power compared to the competitor material which consumed 30% power.
SAF 2507® tapped 168 holes against 112 for the competing material and could even be used for further tapping. The tapping tool used for the competing material had chipping failure on the tool tip.
