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. • 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. • If drilling material thickness of 12.7 mm (0.500") or less, a minimum of 10% reduction in feed is required to minimize material deflection.
