Generic Industrial High Precision ER11 Spring Collet, 1/8 Inch (3.175mm) Precision Clamping Chuck

Product description

Achieve flawless concentricity and peak machining performance with the Industrial High Precision ER11 Collet (3.175mm).

Specially engineered for professional CNC operators, engineers, and manufacturing workshops, this spring collet serves as the critical link between your high-speed spindle motor and micro-diameter cutting tools.

By utilizing an ultra-pure 65 manganese steel alloy that undergoes strict vacuum heat treatment, this collet retains its strong clamping elasticity and shape memory over thousands of tool changes.

What differentiates this collet is its meticulous, mirror-polished cylindrical grind.

The smooth exterior wall eliminates minor surface imperfections, allowing the ER11 clamping nut to distribute torque evenly across the entire length of your 3.175mm or 1/8-inch shank tools.

This uniform radial pressure delivers an exceptionally low runout tolerance (less than 0.008mm), eliminating spindle vibrations, boosting cutting feed rates, and dramatically improving the wall finish of your milled parts.

Whether you are running complex micro-machining jobs in aluminum, engraving intricate signage, or performing routine assembly line lathe operations, this premium hardware component ensures your setup maintains a rock-solid, factory-grade grip.

Engineered to industrial standards with strict runout tolerances (within 0.008mm), ensuring perfect axial alignment and stability to protect delicate micro bits from snapping under load.

Manufactured from heavy-duty 65 Manganese/Titanium hardened steel, providing exceptional elasticity, structural toughness, and shock resistance for extended service life.

Precision-ground and hand-inspected with a smooth, mirror-polished exterior that guarantees a seamless, friction-free fit inside ER11 nut assemblies and spindle shafts.

Explicitly dimensioned to clamp standard 1/8-inch (3.175mm) shank router bits, micro end mills, and engraving pens with maximum gripping force and zero rotational slippage.

Widely utilized in high-RPM CNC spindle motors, automatic lathes, boring machines, and advertising engraving equipment for consistent, heavy-duty processing.
