Product info

OVERVIEW:
The GEN 4 ULTIMAX Case Trimmer utilizes The Taper-Lock cutter head to create clean, consistent and completely trimmed cases in one operation. The cutter head has adjustable carbide blades that will last a lifetime and leave burr-free cuts on the mouth of the case. GEN 4 ULTIMAX Case Trimmer is machined from 6061-T6 aluminum and a combination of 303 and 416 stainless steel. It has been engineered and manufactured 100% in America for a lifetime of service to the end user.
DESIGN:
Case preparation is a necessary evil in the reloading process. The trim operation for rifle cases is especially time consuming unless you are using a GEN 4 ULTIMAX case trimmer. The GEN 4 ULTIMAX is designed from the ground up to make trimming cases easy, fast and accurate. The cartridge case it held by a Brown and Sharpe type collet by the rim. These types of collets are used in the machine tool world because of their accuracy and repeatability. There are 5 collets for the various cartridges one would reload for, from .17 to Cheytac and everything in between. The cartridge case is placed into the collet base first and held in place while the handle is tightened to secure the case for the trimming operation. It only takes about ten degrees of rotation for the handle to secure the case. This design holds the case in the same position regardless of the rim diameter for consistent trim length. The collet assembly is mated to a carriage machined from solid 6061-T6 bar stock and precision fit to ground and polished stainless rods. The spindle is machined from stainless steel and rides in a set of sealed ball bearings which are press fit into the bearing housing which is also machined from solid 6061-T6 bar stock. All the fasteners are black oxide coated and sourced locally.
