Wilson produces two case mouth deburring tools for use in the Wilson Case Trimmer. The deburring tools mount in the cutter bearing and each includes a crank style handle. Cases are held in the trimmer case holders and are held square to the deburring tool. This tool deburs the inside of the case mouth only. The tool is available in the standard 45-degree (WUD45) chamfer and in a 30-degree (WUD30) chamfer for use with VLD bullets. The handle is included, but can be removed to use a Sinclair power adaptor (WSA) so you can power the operation with a drill or rechargeable screwdriver. Not recommended for use on brand new cases.

DON'T USE A CASE HOLDER (16/02/2011)

Using this cutter as instructed will likely produce off-centered chamfering of the case mouth; too much on one side, little to none on the opposite side. This is because the diameter of the bearing (the part of the trimmer tool that holds the rotating cutter shaft) is usually not equal to the diameter of the shell holder, so the cutter isn't centered on the case mouth. The diameter of my bearing is 0.998". I own seven shell holder's and their diameters are: 0.996", 0.997", 0.997", 0.9975", 0.9975", 0.9975", and 0.998" (this last one actually works). I spoke with a Technician at Wilson and he said they can't guarantee consistent diameters for their shell holders because they start with 1" stock and polish them all down by hand, so the resulting diameters are random. Well that works if you're just length trimming, but if you're chamfering they all have to be exactly the same diameter as the bearing. I went back to using my old Hand-Held Chamfering Tool, and soon realized that the reason it works is because it is allowed to self center. So I returned to the Wilson Trimmer Tool, but this time I didn't use a case holder. I just held the case head against the adjustable screw stop using my index finger and thumb, inserted the cutter head into the case mouth, and allowed the case mouth to self-center on the cutter while I turned the crank handle with my other hand. It worked GREAT! I quickly ran 100 cases through and they all had perfectly centered chamfers, all at exactly the same depths! So I figured I'd post what I learned. Maybe this work-around will work for you too. Also, I had my gun smith blue all the parts, as I read that they rust easily.

Don't Use Case Holder! (27/09/2011)

As a general rule, fire-formed cases are NOT symetrical after being fired in factory guns, and therefore the case holder will NOT center the case for chamfering the inside of the case mouth. If you hold the fired case in the matching case holder, you are very likely to get the mouth of the case chamfered unevenly, cutting heavily on one side. One suggestion from another owner of this tool was to hold the case by hand. I tried this and it works accurately, however, I discovered you must cut very lightly and hold the case tightly as the case will want to turn along with the cutter. Also, the uniformer cutting shank is WAY too long and after trimming, in order to chamfer, you must adjust the screw stop about 1/2" back which is rediculous. Wilson needs to work on this as it is inaccurate to use with the case holder on fire-formed cases, and very difficult and time consuming to hold the case by hand when chamfering the inside of the case mouth. This tool is being used in an attempt to accurize handloads for my .308 Caliber rifle.

UPDATE! FIX! (01/10/2011)

My prior review states the problems with this tool as I have personally experienced them. After a bit of thought, I have now discovered the "perfect" solution to one of those problems. As mentioned by the other "reviewer" and myself, do NOT use the case holder to hold the case while chamfering and uniforming the inside of the case mouth as you will end up with a chamfer on one side of the case or an uneven chamfer at best. The solution to accuracy and easy work is simple and cheap. I cut a 1-1/4" length of 3/8" diameter common black rubber air hose and split it lengthwise. Start off your uniforming by slipping the case to be worked into the split rubber hose piece with the base of the shell case slid approximately 1/4" up inside the split hose and the remaining 1" of rubber gripping the case. Now slip the end of the rubber hose up and over the threaded stop. This centers the base nicely on the threaded stop and holds the case in position. Next, using your thumb and two fingers, grip the rubber hose piece with the case securely held inside and chamfer away! This extra "grip" and base centering makes the chore of accurately and uniformly chamfering the mouth of your cases a breeze and after a few cases, your hand won't cramp up in pain from trying to squeeze the case tightly to keep it from spinning. ;)
