The Forster Neck Reamer is a precise tool designed for use with the Original, Classic and Power Case Trimmers. Manufactured from high-grade, wear-resistant tool steel, it ensures durability and consistent performance. The standard Neck Reamers are ground .0025 inches to .003 inches larger than the maximum bullet diameter, providing the ideal fit for your cases. Featuring a staggered tooth design, the reamer smoothly cuts through brass without causing chatter, ensuring a clean cut. Thick case necks can lead to high chamber pressures and cause flyers, but the Forster Neck Reamer efficiently removes excess brass from the neck walls, improving the overall quality of your reloading process. It easily mounts in place of the pilot in the cutter of a Forster Case Trimmer, making it an essential tool for reloaders seeking precision and uniformity.
