Deep Hole Drilling Coolant Adjustment
Recommended Coolant Example If the recommended pressure and flow is 12 Bar and 22 LPM for a standard length holder, then the adjusted pressure and flow for a 3XL holder would be 36 Bar and 66 LPM. 12 • 3 = 36 Bar 22 • 3 = 66 LPM

IMPORTANT: The coolant pressure and flow rate recommendaƟons above represent a good approximaƟon to obtain opƟmum tool life and chip evacuaƟon at Allied Machine recommended speeds and feeds. If lower coolant capabiliƟes exist in a drilling applicaƟon, the T-A® drilling system will sƟll funcƟon at reduced penetraƟon rates. Contact our ApplicaƟon Engineering department for a more specific recommendaƟon of coolant requirements and/or speeds and feeds. 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. Visit www.alliedmachine.com/DeepHoleGuidelines for the most up-to-date informaƟon and procedures. Factory technical assistance is available for your specific applicaƟons through our ApplicaƟon Engineering Team. WARNING
