Haimer A63.140.1/2Z.00 Shrink-fit Holder HSK63A 0.5in

Product Description

The HAIMER A63.140.1/2Z.00 is a shrink-fit tool holder adapter built for CNC machining applications requiring precise, high-rigidity tooling connections. The holder features an HSK63A taper shank interface and accepts a 0.5 inch bore diameter cutting tool. It delivers a 3.5433 inch projection from the gauge line and a 1.8504 inch clamping depth, giving machinists reliable grip depth for end mills and similar tooling. Balanced to 25,000 RPM, this holder suits high-speed spindle work where runout and balance tolerances are critical. It is installed by machinists and CNC setup technicians in production and toolroom environments.

This adapter is suited for HSK63A-compatible CNC machining centers operating at high spindle speeds. The Basic series designation places it in standard production tooling configurations rather than specialized extended-reach or slim-nose variants. It is appropriate for face milling, end milling, and similar operations where a short, rigid toolholder profile benefits process stability. No through-coolant capability is included in this model, so coolant delivery must be managed externally or through the machine spindle if applicable.

Key Features

• HSK63A taper shank for positive, repeatable spindle engagement on compatible machining centers
• 0.5 inch bore diameter with 1.8504 inch clamping depth for secure shrink-fit tool retention
• 3.5433 inch projection from gauge line for standard reach tooling setups
• Balanced to 25,000 RPM for high-speed spindle compatibility
• 0.9449 inch nose diameter for clearance in close-tolerance workpiece applications
• No through-coolant - maintains simple construction for standard tooling setups

Compatibility

Designed for use with HSK63A-compatible CNC machining center spindles accepting 0.5 inch shank cutting tools in shrink-fit retention configurations.

Installation Notes

Shrink-fit holders require an induction heating unit or dedicated shrink-fit machine to thermally expand the bore before tool insertion - never force a tool into a cold holder. Power down and lock out the machine spindle before mounting or demounting the holder. Confirm holder balance rating does not exceed the spindle manufacturer's maximum allowable RPM for the holder series in use. Verify bore diameter and clamping depth compatibility with the cutting tool shank before heating.
