GAETANO CAPORALI ER32 high precision collet DIN ISO 15488 (DIN6499), diameter to choice
(Incl. Tax: €34.43)
The ER32 HP high precision collets according to DIN ISO 15488 (DIN 6499) are designed for accurate clamping of cylindrical tools in ER collet chucks used on CNC machining centers and milling machines. The 12-slot design ensures excellent elasticity and repeatable run-out accuracy up to 0.005 mm when clamping tools with nominal diameter. Precision ground surfaces with Rz 1.6 finish and diameter progression from D2 to D20 in 0.5 mm steps guarantee stable tool holding, high machining accuracy and reliable performance in precision metalworking applications.
The ER32 HP high precision collets according to DIN ISO 15488 (DIN 6499) are designed for extremely accurate clamping of cylindrical cutting tools in ER collet chucks used on CNC machining centers, milling machines and high-speed machine tools.
These collets are manufactured from hardened and precision-ground alloy steel to ensure dimensional stability, elasticity and long service life even under demanding machining conditions. The ER geometry with an 8° taper angle ensures uniform clamping along the entire tool contact surface, improving force distribution and minimizing vibration during machining operations.
The HP (High Precision) version is specifically designed for applications requiring very high run-out accuracy. The guaranteed concentricity of up to ≤ 0.005 mm allows extremely precise machining results and significantly contributes to longer tool life and improved surface quality.
The collets feature a 12-segment slit design, which increases elasticity and ensures excellent clamping repeatability. This design allows the collet to adapt perfectly to the nominal tool diameter while maintaining a strong and uniform grip during high-speed rotation.
The functional surfaces are precision ground with a surface finish of Rz 1.6, which further enhances clamping precision and reduces micro-movement of the tool during machining.
Optimal performance is achieved when the collet is used with a tool diameter corresponding to the nominal collet size. The diameter range is typically available with 0.5 mm increments, allowing precise selection of the correct collet for each tool diameter.
ER32 HP collets are widely used in industries such as automotive manufacturing, aerospace production, mold and die machining, precision mechanical engineering and high-performance CNC machining, where precision, reliability and repeatable tool clamping are essential.
Thanks to their robust design and compliance with international standards, these collets represent a reliable solution for CNC operators, production engineers and machining specialists requiring high-performance tool holding systems.
