570 forum posts 18 photos	I recently bought a 1/8 inch ER20 collet from ArcEuro. I have bought many from there before and they have been very good but the 1/8 inch one has a 4mm dia.centre drilled entrance hole at the business end which means it cannot hold my very short job as it is not gripped adequately. Arc Euro offerred a refund but tell me that such a collet end is not a problem in their experience. The strange thing is , that after 50 years in the engineering industry, I have never come across a collet that does not have a nearly sharp edge there. Any thoughts? Is this unusual in your experience? Colin
