The Forster Case Trimmer is one of the most versatile reloading tools available on the market today. It utilizes an extremely accurate Brown and Sharpe type collet to hold the case. Pilots are used to support the case neck during case trimming. A Collet and pilot are needed to operate this trimmer and are sold separately. Trimmer can be used for case length trimming, hollow pointing, neck turning, inside neck reaming, case mouth deburring, and primer pocket reaming (removes military crimps). The trimmer can be powered by a drill or power screwdriver by adding the Forster Power Adapter (#FPA1000).
