Haimer 85.700.40 Cooling Tube HSK40A HSK40E

Product Description

The HAIMER 85.700.40 is a rotary tool holder cooling tube designed for use with HSK spindle and HSK holder assemblies in CNC machining environments. This cooling tube delivers coolant directly through the tool holder to the cutting zone, supporting through-spindle coolant (TSC) capability in high-precision milling and machining operations. Compatible with HSK40A and HSK40E taper sizes, this part measures 3 inches in length, 2 inches in width, and 1 inch in height, weighing approximately 0.03 pounds. Installation is typically performed by CNC machine tool technicians or tooling setup specialists during spindle or holder maintenance.

This cooling tube is suited for production machining centers running HSK40A or HSK40E taper tool holders where controlled coolant delivery is required. It is used in applications where through-spindle coolant improves chip evacuation, extends tool life, or maintains thermal control at the cutting interface. The lightweight construction makes it appropriate for high-speed spindle environments where rotational balance is a consideration.

Key Features

• Designed for HSK40A and HSK40E taper sizes
• Compatible with HSK holder and HSK spindle assemblies
• Supports through-spindle coolant delivery to the cutting zone
• Compact and lightweight at 0.03 pounds
• Direct OEM-style replacement for rotary tool holder cooling tube applications

Compatibility

Compatible with HSK holder and HSK spindle assemblies using HSK40A and HSK40E taper sizes, as specified in product data.

Installation Notes

Installation should be performed by a qualified CNC tooling technician or machine tool specialist. Before servicing the spindle or tool holder assembly, power down the machining center and depressurize any active coolant circuits per the machine manufacturer's lockout/tagout procedures. Do not overtighten or force-fit the cooling tube, as HSK taper interfaces require precise seating to maintain balance and coolant seal integrity.
