The “World’s Finest Trimmer” lets you trim more cases in less time - and with less effort - using your electric drill as a power source. The adjustable cutter rotates and shortens the case until the shoulder contacts the close-fitting stop that is mounted in a bearing to prevent it from rotating and marring the case. Simply pick up a case and push it against the cutter until the excess brass is removed. Once you have the trimmer set up and get a rhythm going, you can easily maintain a pace of 8-10 cases per minute – a joy to use! Durable aluminum and stainless steel construction, with a high-speed steel cutter for years of reliable service. Units only trim cartridge cases to length. They do not chamfer or deburr the case mouth during trimming.
