Techniks 35472 Shrink-fit Tool Holder HSK63A Taper Shank

Product Description

The TECHNIKS 35472 is a shrink-fit tool holder adapter designed for CNC machining centers and milling applications requiring precise, high-rigidity tooling connections. Featuring an HSK63A taper shank, this adapter provides a secure, balanced interface between the machine spindle and cutting tool. The 0.55-inch nose diameter and 6.0-inch overall length make it suitable for a range of tooling setups, while the through-coolant design delivers cutting fluid directly to the tool tip to manage heat and extend tool life. Machinists and CNC technicians rely on shrink-fit holders for superior runout performance and grip strength compared to collet-based systems.

This adapter is suited for horizontal and vertical machining centers equipped with HSK63A spindle interfaces. Through-coolant capability makes it especially effective in high-speed or deep-pocket machining operations where direct coolant delivery to the cutting zone is required. The 120 mm projection provides adequate clearance for a variety of workholding and part geometry configurations. Installation is handled by qualified CNC toolroom technicians using an induction heating shrink-fit unit.

Key Features

• HSK63A taper shank for high-speed, high-rigidity spindle connection
• 0.55-inch nose diameter accommodates compatible shrink-fit tooling
• Through-coolant design routes cutting fluid directly to the tool tip
• 6.0-inch overall length with 120 mm projection for workholding clearance
• 5/32-inch hole diameter for precise tool bore fitment

Compatibility

Designed for use with CNC machining centers equipped with an HSK63A spindle interface and compatible with shrink-fit tooling systems requiring a 0.55-inch shank diameter.

Installation Notes

Installation requires an induction-style shrink-fit heating unit to expand the bore before seating the cutting tool; never attempt to force a tool into a cold holder. Power down and lock out the machine spindle before handling or changing tooling assemblies. Verify holder balance rating and runout tolerance against machine specifications before high-speed operation. Follow shop safety protocols and machine tool manufacturer guidelines for HSK tooling changes.
