Omega Products HSK63A Shrink Fit Chuck - G2.5 - 25,000 RPM - 6mm - 160mm Long

The Omega Products HSK63A Shrink Fit Chuck is a precision tool-holding accessory designed for HSK63A spindles. It uses a quick heating and cooling process to uniformly expand the chuck, allowing tool shanks to be inserted and gripped with a strong, even clamping force. This eliminates tool slippage, delivers maximum rigidity, and helps extend tool life while improving cutting performance in high-speed work.

With a 160 mm length and a G2.5 interface, it provides precise tool positioning and reliable performance for a wide range of tools from 3 mm to 32 mm shanks. Capable of handling up to 25,000 RPM, it’s well suited to demanding milling, drilling, and finishing tasks where consistency matters.

• Broad shank compatibility (3–32 mm): Supports a wide range of cutting tools with a single chuck, reducing setup time and inventory while keeping tooling flexible for diverse jobs.
• Uniform shrink-fit clamping: Heating and cooling expand and contract the chuck evenly, delivering a strong, uniform grip that minimizes runout and tool slippage for stable, repeatable cuts.
• G2.5 interface with high-speed readiness: Ensures precise tool positioning and alignment on spindles, optimized for up to 25,000 RPM to maximize performance in high-speed machining.

This shrink-fit solution combines broad tool compatibility, dependable clamping force, and high-precision positioning to deliver consistent results, reduce downtime, and extend tool life across a variety of milling, drilling, and finishing applications in professional shops and serious hobbyist setups alike.
