JRM, Inc. has conventional coring tines in two styles, Premium and Dillennium?. A Premium tine is identical to the corresponding Dillennium? tine in all respects except that it does not have the D22 tip. As compared to a typical OEM tine, a Premium top-eject should deliver a minimum 300-400% performance increase. This is due to the design and quality of steel used. A Dillennium? tine will give 700%+ performance increase as compared to a typical OEM tine. Dillennium? tines are frequently available in a side-eject version as well as a tubular top-eject. All JRM coring tines are made of the finest available 4130 high-carbon alloy steel.
