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 recommendations above represent a good approximation to obtain optimum tool life and chip evacuation at Allied Machine recommended speeds and feeds. If lower coolant capabilities exist in a drilling application, the T-A® drilling system will still function at reduced penetration rates. Contact our Application Engineering department for a more specific recommendation 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 initial hole that is a minimum of 2 diameters deep. - Do not rotate tool holders more than 50 RPM unless it is engaged with the workpiece or fixture. Visit www.alliedmachine.com/DeepHoleGuidelines for the most up-to-date information and procedures.
