Seco 02753292 Shrink-fit Tool Holder Adapter CAT40

Product Description

The SECO 02753292 is a shrink-fit tool holder adapter designed for precision CNC machining applications. It features a CAT40 taper shank and accepts tooling with a 0.5512-inch hole diameter. Overall length measures 6.193 inches, with a 3.5-inch projection and a 1.063-inch nose diameter. The adapter includes through-coolant capability, delivering cutting fluid directly to the tool tip for improved chip evacuation and tool life. It is balanced to 38,000 RPM, making it suitable for high-speed machining centers where runout and balance are critical to surface finish and spindle health. Machinists and CNC technicians install this adapter in shop and production environments.

This shrink-fit adapter is suited for vertical and horizontal machining centers equipped with a CAT40 spindle interface. It is commonly used in high-speed finishing and semi-finishing operations where rigid tool holding and minimal runout are required. The through-coolant port supports wet machining strategies on ferrous and non-ferrous materials. Clamping depth of 1.339 inches provides secure shank retention after induction heating and shrink-fit assembly. This adapter is appropriate for production shops running extended tool life programs or high-RPM operations.

Key Features

• CAT40 taper shank for compatibility with standard CAT40 spindle interfaces
• 0.5512-inch (14 mm) hole diameter for precise shrink-fit tool retention
• Through-coolant design delivers fluid directly to the cutting zone
• Balanced to 38,000 RPM for high-speed machining center use
• 3.5-inch projection and 1.339-inch clamping depth for stable, extended-reach setups
• 1.063-inch nose diameter provides clearance in tight workpiece features

Compatibility

Designed as an OEM-style shrink-fit tool holder for CAT40 spindle machining centers requiring a 0.5512-inch bore shrink-fit adapter with through-coolant capability.

Installation Notes

Shrink-fit tool holders require an induction heating unit to expand the bore before tool insertion — never attempt to force a tool shank into a cold shrink-fit holder. Allow the holder to cool completely and reach ambient temperature before mounting in the spindle or measuring runout. Inspect the bore and tool shank for contamination or damage before each use. Installation and removal should be performed by a qualified CNC toolroom technician following the machine tool manufacturer guidelines and applicable shop safety procedures.
