SPECIALS

NOTE: The speeds and feeds listed above are based on a rigid setup using air mist through tool coolant. Speed may be increased up to 50% if using high pressure flood or through coolant. NOTE: If drilling dry without coolant, speed must be reduced significantly based on setup, drill depth, and material hardness. Up to 50% speed and feed reducƟon may be necessary in these types of applicaƟons. Contact the ApplicaƟon Engineering department for assistance. email: engineering.eu@alliedmachine.com
