Deep Hole Drilling Speed and Feed Adjustment Holder Length

Recommended Speed and Feed Example If the recommended speed and feed is 50 M/min and 0.20 mm/rev for a standard length holder, then the speed and feed using a 3XL holder in the same applicaƟon would be 37.5 M/min and 0.18 mm/rev.

mm/rev = feed rate (mm/rev)

DIA

Tool failure can cause serious injury. To prevent: - When using holders without support bushing, use a short T-A® holder to establish an iniƟal hole that is a minimum of 2 diameters deep. - Do not rotate tool holder more than 50 RPM unless it is engaged with the workpiece or fixture.

Factory technical assistance is available for your specific applicaƟons through our ApplicaƟon Engineering Team. WARNING
