LYMAN 7810199 · Standard Deburring Tool
Chamfer trimmed cases from .17 to .45 inside and deburr outside
The hardened, double-sided hand tool removes burrs on the case mouth and creates a controlled inside chamfer – without power or separate holder.

Standard model .17–.45 · not Extra Large

Classification before purchase

Practical use: A freshly trimmed case can have sharp inside and outside edges. The LYMAN 7810199 smooths both sides, making the next step more consistent.
The variant is crucial: This offer is the standard model up to .45, not the separately available Extra Large tool for bigger cases.



Fits well

Cases from .17 to .45 caliber
Manual batch work after trimming
Reloaders who want to work the inside and outside edge with one tool



Fits less well

Cases over .45 caliber
Those who want motorized
en Drive or fixed tool station expected
Repair of cracked or deformed case mouths


Features with practical effect


Two working sides
Inside chamfer and outside deburring are each done with the matching side. One tool covers both edges.


Self-centering guide
The geometry supports straight positioning but does not replace even, light pressure.


Hardened tool surfaces
The precision-machined cutting edges are designed for repeated manual case preparation.


Compact hand operation
Ready to use immediately without holder or power and good for controlled single or batch processing.


Limits, disadvantages and avoiding bad purchases

Standard model, not Extra Large: The confirmed range ends at .45 caliber. For larger cases, the appropriate separate LYMAN model is required.
Only remove the burr. Excessive chamfering weakens the edge and can worsen uniformity. Cracks, severe deformations or other damage are reasons for rejection.

Application and safety

FAQ
For which calibers is 7810199 suitable? LYMAN specifies .17 to .45 caliber for this standard model.
Does it work both sides of the case mouth? Yes. One tool side is for the inside chamfer and the other for removing the outside burr.
Is it suitable for cases over .45? No. LYMAN offers a separate Extra Large model for that.
How much material should be removed? Only enough to remove the burr and create a uniform edge. High pressure is not advisable.
Does the tool replace a trimmer? No. The case is trimmed to length first; the tool then only processes the edges.

Black-Raptor classification
Clear standard solution for hand operation: 7810199 is useful if your caliber is in the .17–.45 range and you deliberately work manually. For larger cases or motorized stations, you need a different variant.
