Haimer E40.140.08 Shrink-fit Tool Holder HSK40E

Product Description

The HAIMER E40.140.08 is a shrink-fit tool holder adapter designed for precision CNC machining applications. It features an HSK40E taper shank interface and accepts cutting tools with a 0.315 inch (8 mm) hole diameter. With a projection length of 3.1496 inches (80 mm) and a nose diameter of 0.8268 inches (21 mm), this adapter provides the rigid, concentric grip that shrink-fit technology is known for. It is balanced to 25,000 RPM, making it suitable for high-speed machining operations. Machinists, toolroom technicians, and CNC setup personnel work with this class of tooling in production and job-shop environments.

This adapter is intended for use in CNC machining centers equipped with HSK40E spindle interfaces. The HSK40E connection is common in high-speed, light-duty, and compact machining center spindles. The 3.1496 inch projection suits applications where extended reach is required while maintaining rigidity. A clamping depth of 1.4173 inches (36 mm) ensures a secure grip on the tool shank when thermally contracted. No through-coolant capability is present on this holder, so external or mist coolant strategies apply for chip and heat management.

Key Features

• HSK40E taper shank for high-speed CNC machining center spindles
• 0.315 inch (8 mm) bore diameter accepts standard shrink-fit tooling
• Balanced to 25,000 RPM for high-speed operation
• 3.1496 inch projection length for extended-reach applications
• 1.4173 inch clamping depth delivers strong thermal grip on tool shanks
• No through-coolant - suited for external or mist coolant setups

Compatibility

Designed for use in CNC machining centers with HSK40E spindle interfaces. Compatible with shrink-fit tools having a 0.315 inch shank diameter. Specific machine model compatibility should be verified against spindle interface drawings before installation.

Installation Notes

Shrink-fit tool holder adapters require an induction heating unit to thermally expand the bore before tool insertion and release. Always allow the holder to cool completely and reach thermal equilibrium before measuring runout or placing the assembly in service. Spindle interface cleanliness is critical - inspect and clean the HSK taper and spindle before mounting. Installation should be performed by qualified CNC toolroom personnel following the machine tool builder guidelines for HSK tooling.
