This neck reamer works with Forster's original, classic and power case trimmers. Made from tough, wear-resistant steel, it's precisely ground 0.0025 inches - 0.003 inches over the bullet's max diameter to clean out excess brass. Its staggered tooth design delivers a smooth, chatter-free cut. Overly thick necks can raise chamber pressure and throw off bullet accuracy. Installed in place of the pilot on the case trimmer, the neck reamer efficiently trims the neck wall and should be used after firing but before sizing.

• Engineered from premium-grade, wear-resistant tool steel for enhanced durability and performance
• The staggered tooth configuration ensures seamless brass cutting, minimizing vibration and eliminating chatter for optimal precision
• Install the case trimmer cutter shaft in place of the pilot
• Precision-machined to a tolerance of 0.0025 inches - 0.003 inches greater than the specified bullet diameter
