ER32-86.3mm High-precision ER32 chuck spring collet for engraving machines and drill bits, with a high precision of 0.008mm.

1、The concave table design in front of the chuck cone prevents dust and iron chips from directly entering during work, which affects the accuracy of the tool holder. 2、The collet hole slot adopts grinding process, which is more suitable for high‑speed processing. 3、After cryogenic treatment, the wear resistance of the product is significantly improved. 4、The accuracy and life of repeated clamping can be increased by about 50%. 5、Widely used in milling, boring, drilling, wire tapping operations, applicable to various CNC, engraving machines and other equipment.Item Type: Spring Collet Material: 65Mn Model: ER32 Applicable Machine Tool: Lathe Product Accuracy: ≤0.008mm Clamping Range: Approx. 3 ~ 20mm / 0.1 ~ 0.8in Size: Approx. 8 x 6.3mm / 0.3 x 0.2in Height: Approx. 40mm / 1.6in Diameter: Approx. 33mm / 1.3in Uses: Widely used in milling, boring, drilling, wire tapping, and various CNC, engraving machines and other equipment. 1 x Spring Collet
