After high-frequency quenching treatment, good low-temperature impact toughness and good clamping performance, the clamping is more stable
The surface is grinded and polished, which is highly wear-resistant and heat-resistant, and the bright outer surface fits better, ensuring excellent accuracy
Widely used in milling, boring, drilling, wire tapping operations, suitable for various CNC, engraving machines and other equipment
More stable performance, not easy to deform, longer service life
Our ER collets are manufactured from high-grade carbon steel (65Mn) and undergo high-frequency quenching and low-temperature treatment to ensure excellent durability, wear resistance, and toughness.
The ER collets feature high precision with an accuracy rating of 0.008mm (0.0006 inches), ensuring stable and reliable clamping during operation.
We offer a wide range of sizes including ER16, ER20, ER25, and ER32. The ER16 set comes with 12 pieces and is available in inch sizes.
These collets are widely used in milling, boring, drilling, and wire tapping operations. They are suitable for various CNC machines, engraving machines, and other machining equipment.
The low-temperature treatment and high-frequency quenching process provide stable performance, making the collets highly resistant to deformation, and significantly extending their service life.
Yes, thanks to their high-grade carbon steel construction and HRC44-48° hardness, they provide strong clamping force and large elastic force suitable for demanding machining tasks.
