SINCLAIR/L.E. WILSON - SINCLAIR CASE MOUTH DEBURRING TOOL WITH HOLDER

I'm switching over from cast to plated bullets and in my research it is recommended to deburr "new" brass to prevent any possible nicks in the plating. For large batches you can use this tool in a 1/4" cordless screwdriver (200 variable rpm max) because this Wilson deburring tool is really sharp and doesn't require a lot of pressure or rpm to get the job done. For small batches I use my K&M handle, this tool fits perfectly and easy on the wrist.

I purchased this item to use with my L.E. Wilson inside/outside 45 degree chamfer tool. It works like it was made for it, which of course it was! There are chamfer tools with a round shaft that will work in a drill press, but the gun sites don't seem to carry them any more. This adapter allows you to do that with the combo tool. I use it to chamfer the throat of the chamber on black powder reproduction/replica guns cylinders. Makes for easy starting the round balls, and less lead shaving. Brownells also sells a 45 degree brass lapping tool that does have the drill press stem. Use this with their lapping compound to get a smooth finish. See picture.

Deburring and chamfering were my least favorite operations of case prep. Now they're a breeze. Just make sure you follow the recommendation an use a Wilson chamfering tool, which I already had. I used to get the worst hand cramps when I would twist the chamfering tool by hand. This holder eliminates that and is much faster to boot! I have mine inserted into my B&D cordless screwdriver, but a drill works too. I just wish I had purchased one of these years ago.

This is great combo. The Wilson deburr tool is very nicely made and sharp. The holder is also really nicely made, with unusually good attention to detail. Thanks, Sinclair, for offering a unique product.

Not sure why some people give it 2 stars when they're trying to use the wrong deburring tool inside... It's made for the Wilson deburring tool, and fits 100% perfectly, and works GREAT!!!
