Forster Inside/Outside Deburring Tool .17 to .45 cal

The Forster Inside/Outside Deburring Tool for .17 to .45 caliber is a precision reloading accessory engineered to eliminate case mouth burrs and perform chamfering operations on both the interior and exterior of cartridge cases. This double-ended, multifunction tool addresses one of the most critical prep steps in ammunition reloading—removing sharp edges and burrs that compromise seating consistency, increase bullet runout, and accelerate primer pocket wear.

Forster's deburring tool operates in two configurations: mounted to a lathe via an optional Deburring Tool Base for high-volume production, or used by hand for single-pass processing. The .17 to .45 caliber range accommodates centerfire rifle cartridges from .17 Hornet through .458 Winchester Magnum, as well as common handgun rounds including 9mm, .40 S&W, .45 ACP, and intermediate magnum pistol loads. Hand operation eliminates the need for motorized equipment and delivers tactile feedback that helps detect and correct case-wall inconsistencies during the deburring process.

This tool is essential for reloaders seeking ammunition that matches mil-spec tolerances or targets competitive accuracy standards. Precision handloaders, ammunition manufacturers, and shooters running match-grade loads benefit from the improved case concentricity and primer pocket uniformity that proper deburring delivers. At 0.11 lbs and compact dimensions (1.75 x 0.85 x 3.45 inches), the tool integrates seamlessly into any bench setup without consuming significant workspace.

Forster products occupy a recognized position in the reloading market for build quality and functional design. This deburring tool's dual-purpose construction—inside and outside processing in a single tool—reduces the number of separate instruments required, streamlining case prep workflow without sacrificing precision or durability.
