Lyman
The Lyman 7810199 Multi-Caliber Deburring Tool is a case mouth chamfering essential for reloaders who want clean, consistent ammunition from fired brass. After trimming cases to length, sharp edges at the case neck can cause seating problems and create inconsistent bullet engagement. This handy two-stage tool addresses both issues—chamfering the inside and outside of the case neck in one operation to remove burrs and create a smooth transition that helps bullets seat reliably and evenly.
Built from hardened steel, the standard deburring tool covers the majority of rifle and pistol work, handling calibers from .17 through .45. If you reload larger rounds like .50-70, .505 Gibbs, or other big-bore cartridges, an extra-large version is available to handle cases up to .60 caliber. Either way, you're investing in a tool designed to withstand years of regular bench use without wear or performance degradation.
Proper case prep—including deburring—directly affects ammunition consistency, safety, and component fit. A few seconds per case with this tool becomes part of a repeatable process that pays dividends downrange. Whether you're fine-tuning precision rifle loads or streamlining pistol ammo production, a quality deburring tool belongs in every serious reloader's kit.
| Brand | Lyman |
| Model | 7810199 |
| Product Type | Case Mouth Deburring / Chamfering Tool |
| Caliber Range | .17 to .45 caliber (standard) |
| Material | Hardened Steel |
The standard Lyman 7810199 model handles .17 through .45 caliber cases. If you reload larger rounds like .50 BMG, .505 Gibbs, or other magnums and big-bore cartridges, Lyman offers an extra-large version rated for cases up to .60 caliber.
When you trim cases to length, the cutting process leaves sharp burrs on the inside and outside edges of the case neck. This tool simultaneously chamfers both surfaces, removing those burrs and creating a smooth transition. The result is easier, more consistent bullet seating and better concentricity in your finished rounds.
The deburring tool works for both rifle and pistol ammunition prep. Any centerfire or rimfire cartridge within the .17–.45 range benefits from proper case mouth finishing before bullet seating.
Lyman builds this tool from hardened steel, designed to withstand years of regular reloading bench use without dulling or requiring replacement. With normal care, it's a one-time purchase for your case prep setup.
