What’s A Chamfering Tool?

Uniburr+ Chamfer ToolChamfer Tool

A Chamfer or deburring tool is used to create a bevel or furrow on the end of a bolt. Today we are going to share our recommendation for this tool: the Uniburr+. The Uniburr is a deburring tool that attached to the end of a drill to help mend the tip of a bolt. If you had to cut a bolt or threaded rod you may need to use a tool like this one to fix the threading.

Once cut, a bolts threads can become uneven or warped. This will make it impossible to screw a nut onto the bolt. There are two versions of the Uniburr available which have different material capabilities. We have broken down the two types in the table below for you:

Using the 1816 Uniburr PlusUniburr in drill

The chamfer tool we will be showing today is the 1816 Uniburr Plus. A tool that we use to deburr threaded rod in our own warehouse!

It’s a very simple tool to use, the base of the uniburr is made to be gripped by a regular drill chuck. Simply fit it into the end and let the chuck grip tighten onto the insert.

The next thing you will want to do is secure your bolt into a vice so that it will not move around during the process.

Now its time to apply your most valuable tools. Put on your safety glasses and gloves to keep yourself safe!

After securing the bolt and putting on your safety gear, place the uniburr tool onto the bolt tip and VERY SLOWLY begin spinning the tool. The angled blades will begin to cut into the bolt tip and expose clean threads suitable for a nut to screw onto.

This tool will require you to take your time. If you work the tool too fast it will burn out fairly quickly. Apply steady pressure and ensure that the blades never spin backwards as this will damage the blades.
