The Precision Prep Tool, from Little Crow Gunworks, LLC. The first manually operated case prep tool that puts four tools at your fingertips. Most other designs utilize inline tools which require the user to twist their wrist or rotate the tool in their hand. The PPT consists of a knurled solid aluminum handle with a bearing mounted aluminum tool head. The tool head has four 8-32 tapped holes which accept case prep tools manufactured by most reloading companies. The offset design is much more ergonomic as the user simply rotates their forearm in a clockwise motion to chamfer, deburr, clean the primer pocket or de-crimp military brass or any other operation that can be accomplished with an 8-32 threaded tool.Note: This is the Precision Prep Tool only, the Precision Prep Tool Set is sold separately (Part# 395092).
