Seco 03098289 Shrink-fit Tool Holder Adapter HSK63A

Product Description

The SECO 03098289 is a shrink-fit tool holder adapter with an HSK63A taper shank designed for precision CNC machining applications. It accepts a 14 mm bore diameter and delivers a 64 mm projection length with a 34 mm clamping depth, providing a rigid, concentric grip on cutting tools. The adapter includes through-coolant capability, directing coolant directly to the cutting zone to improve chip evacuation and extend tool life. It is installed by machinists and tooling technicians on machining centers equipped with HSK63A spindle interfaces.

This adapter is suited for horizontal and vertical CNC machining centers running high-speed or high-precision operations where thermal shrink-fit clamping is preferred over collet or side-lock systems. The through-coolant feature makes it well matched to deep-cavity milling, drilling, and reaming operations where flood coolant cannot adequately reach the cutting edge. The 27 mm nose diameter and 122 mm overall length are standard dimensions for this class of HSK63A shrink-fit tooling. Series E93045403.

Key Features

• HSK63A taper shank for high-speed spindle interfaces with positive axial and rotational location
• 14 mm bore diameter with 34 mm clamping depth for a secure shrink-fit grip
• Through-coolant design channels coolant directly to the cutting zone
• 64 mm projection length and 27 mm nose diameter suit a range of milling and drilling operations
• 122 mm overall length in a compact, balanced form factor for high-rpm use

Compatibility

Designed as an OEM-style shrink-fit tool holder adapter for CNC machining centers equipped with an HSK63A spindle interface.

Installation Notes

Installation requires a shrink-fit induction heater sized for the bore diameter; never use an open flame to expand the bore. Confirm spindle interface cleanliness and check the HSK taper for nicks or contamination before mounting. Power down and lock out the machining center before performing any tooling changes. Follow the machine tool builder guidelines and applicable shop safety procedures for shrink-fit tooling assembly.
