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 reduction may be necessary in these types of applications. Contact the Application Engineering department for assistance. ext: 7611 | email: appeng@alliedmachine.com NOTE: If drilling material thickness of 0.500" (12.7 mm) or less, a minimum of 10% reduction in feed is required to minimize material deflection.
