ER32 Sealed Collet 10mm, Collapse range=1.0mm

ER32 Sealed Collet 12mm, Collapse range=1.0mm

• Diameter Size : 15
• Made of high alloy spring steel
• Hardened surface to 44-48 HRC
• Maximum gripping force
• Runout precision : 0.0004″

• Higher gripping force due to the optimized slot design, providing more secure tool clamping.
• Increased rigidity compared to full-slot designs, helping reduce collet deflection under heavy cutting loads.
• Reduced vibration and chatter, resulting in improved surface finish and longer tool life.
• Better suited for heavy milling operations, especially with larger diameter end mills and higher cutting forces.
• Maintains an effective coolant seal, delivering coolant efficiently to the cutting zone while minimizing leakage.
• Improved machining accuracy through more stable tool holding and reduced runout.
• Longer collet life, as the modified slot design distributes clamping stresses more evenly.
• Compatible with standard ER collet chucks designed to DIN 6499 / ISO 15488 specifications.
