Values should be varied depending on the power ortions and enhanced tool life. A large coolant volume should be supplied,G rigidity of the machine to be used. Optimum conditions should be selected especially when drilling difficult-to-cut materials. depending on the actual chip control or damage on edges. • When drilling stainless steel with low machinability such as austenitic • When using the smaller diameter tools in each range, set the feed “f” to stainless steel with a depth deeper than L/D = 3, a pecking cycle or inter- the lower recommended values. nal coolant supply is recommended.
