Haimer A10.144.3/8Z.4 Shrink-fit Holder HSK100A

Product Description

The HAIMER A10.144.3/8Z.4 is a shrink-fit tool holder adapter with an HSK100A taper shank, designed for precision toolholding in CNC machining centers. It accepts a 0.375 inch hole diameter and provides a 5.12 inch projection, making it suited for deep-reach milling, drilling, and boring applications. Through-coolant capability directs cutting fluid directly to the tool tip, supporting chip evacuation and thermal control at the cutting zone. The adapter features Cool Jet technology and resealable bores, and is balanced to 25,000 RPM for high-speed spindle performance. Installation and tool changes are handled by toolroom technicians or CNC setup personnel using induction shrink-fit equipment.

This adapter is used in industrial machining environments where HSK100A spindle interfaces are present, typically on high-speed machining centers running tight-tolerance work in ferrous and non-ferrous materials. The 0.94 inch nose diameter and 1.65 inch clamping depth accommodate standard shank tooling in that bore class. The through-coolant path and resealable bore design make it appropriate for applications requiring high-pressure coolant delivery. It is suitable for production shops, tool cribs, and precision job shops running balanced tooling at elevated spindle speeds.

Key Features

• HSK100A taper shank for rigid, repeatable spindle interface on compatible machining centers
• 0.375 inch (3/8 inch) bore diameter with 1.65 inch clamping depth for secure tool grip
• 5.12 inch projection for extended reach toolholding applications
• Through-coolant capable with Cool Jet technology and resealable bores
• Balanced to 25,000 RPM for high-speed machining with minimal vibration
• 0.94 inch nose diameter for clearance in tight-pocket machining scenarios

Compatibility

Designed for use with machining centers equipped with an HSK100A spindle taper interface. Accepts 0.375 inch shank tooling within the specified clamping depth range.

Installation Notes

Installation requires an induction shrink-fit heating unit rated for HSK100A holders; never attempt to seat or release tooling by mechanical force. Power down the machining center and allow the spindle to come to a complete stop before changing holders. Follow the machine tool builder and toolholder manufacturer guidelines for heating temperature and cool-down time before securing the assembly. Confirm dynamic balance specifications are met before running at elevated RPM.
