Drilling Different Size Holes with a MultiSpindle Head
Close spaced hole tend to be uniform in size but there are situations where a hole pattern has hole sizes that differ. If the difference in hole size among the cluster of holes is less than 30-50% than the spindle speed can be set to allow drilling the largest hole size without affecting the tool life. Our Recommended Tool Speed Chart can be used as a guide for tooling speeds for standard high-speed tooling in common materials.
