Description
The L.E. Wilson Uniform Burring Tool in the 45 degree configuration turns your Wilson Case Trimmer into a dedicated chamfering station. It handles the inside of the case mouth, shaving off any burrs left behind after trimming so your brass is ready for a smooth, square bullet seat. For reloaders who already run the Wilson trimmer, this is one of those accessories that just makes the whole process tighter and more repeatable.
How the UBT-45 Works at the Bench
The tool mounts in the cutter housing, right where the trimmer cutter normally sits. Your cases load into the standard Wilson trimmer case holders, which keeps every piece of brass held square to the cutting edge. That squareness is the whole point here, since a consistent chamfer means fewer shaved jackets and more uniform bullet seating across a batch. The 45 degree taper is the standard angle most reloaders reach for on conventional bullets.
Built From Hardened Ground Steel
L.E. Wilson has been a family owned shop since 1927, and their tooling reputation shows up in this piece. The burring tool is made from hardened ground steel with precision ground flutes, so the cutting edges stay sharp and produce a clean, uniform finish case after case. It is made in the USA and sized to work across a wide range of brass, from .17 up through .45 caliber.
Crank Handle Included, Power-Adaptor Friendly
Every UBT-45 comes with a crank style handle for manual operation, so you can get to work the moment it arrives. If you prefer to speed things up, the handle removes and the tool accepts the Sinclair power adaptor, letting you run it off a drill or rechargeable screwdriver when you have a big pile of brass to prep. It is a simple, no-nonsense tool that pairs perfectly with a case prep bench you already trust.

Frequently Asked Questions
What does the L.E. Wilson 45 Degree Uniform Burring Tool fit?
It mounts in the cutter housing of the L.E. Wilson Case Trimmer, right where the standard trimmer cutter sits. Your brass loads into the regular Wilson trimmer case holders, which hold each case square to the tool. It works across a broad range of brass, from .17 up through .45 caliber.
What is the difference between the 45 degree and 30 degree Wilson burring tools?
L.E. Wilson makes both a standard 45 degree and a 30 degree version. The 45 degree taper is the conventional angle most reloaders use for everyday chamfering, while the 30 degree is geared toward VLD style bullets that benefit from a longer taper. If you are loading standard bullet profiles, the 45 degree is the usual pick.
Does the UBT-45 come with a handle, or can I power it with a drill?
A crank style handle is included so you can use it by hand right out of the package. The handle also removes so you can run the tool with a Sinclair power adaptor, which lets you drive it with a drill or rechargeable screwdriver. That is handy when you have a large batch of brass to deburr.
Does this tool chamfer the inside or outside of the case mouth?
The Wilson Uniform Burring Tool deburs the inside of the case mouth only. That inside chamfer is what smooths bullet seating and helps keep your loads consistent. For outside deburring you would use a separate tool.
