What is the best surface speed for milling pre-hard D2 tool steel with carbide end mill?
B
250-450 SFM is the best surface speed for milling pre-hard D2 tool steel with carbide end mill.
WHY
This range balances tool life and efficiency when milling pre-hardened D2 with carbide. Pushing faster than 450 SFM can wear your tools too quickly. Consider slowing down your roughing SFM to get the most out of your tool.
