3/8 ER20 Sealed Collet
- 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.
- Made of high Alloy Spring Steel
- Surface hardened to 44-48 HRC
- Maximum gripping force
- Runout accuracy : 0.0004″
- Size : 3/8
- Overall Diameter : 21mm
