ER Collet | High Precision ER11 / ER16 / ER20 / ER25 / ER32
Collet is an indispensable precision component of a CNC machine tool, designed to provide solid andaccurate centering of the milling cutter. lt is finely engineered to ensure a high degree of concentricity is maintained throughout the milling process, thus reducing vibration and improving cutting results.
Wide Range of Sizes with Excellent Value
We offer multiple ER collet dimensions all in one place, giving you the flexibility to choose exactly what you need. With high cost-performance and reliable quality, our collets provide exceptional value for both small workshops and large manufacturing operations.
Ultra-High Precision Concentricity
Each collet is engineered for outstanding accuracy, featuring real concentricity as low as 0.005mm. This high level of precision ensures stable tool clamping, reduced vibration, and improved machining performance.
High-Quality Material with Custom Options
Made from premium 65Mn spring steel with a hardness of HRC44–48, our collets deliver excellent durability and long service life. Custom logo laser engraving is also available to support branding and OEM requirements.
ER High-Precision Collects
High-precision ER Collet with 0.008mm real concentricity. ER11 / ER16 / ER20 / ER25 / ER32 full sizes available. Best for CNC machines, milling, drilling and engraving.
CNC Milling and High-Precision Machining
ER Collets are widely used in CNC milling centers and precision machining tasks. Their stable clamping force and high concentricity ensure accurate tool positioning, reduced vibration, and improved surface quality during metal cutting and contouring.
CNC Routers and Woodworking Equipment
In woodworking, engraving, and CNC router applications, ER Collets provide reliable tool holding for router bits, carving tools, and trimming cutters. They support both metric and imperial tool sizes, making them ideal for furniture manufacturing, sign-making, and general woodworking.
Drilling, Boring, and Tapping Machines
ER Collets deliver secure and steady clamping for drills, taps, reamers, and other rotating tools. Their precision and durability make them suitable for high-speed drilling, deep-hole machining, and industrial tapping operations across metalworking and automated production lines.
