This drill-mounted tool fits in the chuck of an electric drill.
It is designed to almost instantly produce a burr-free threaded end to a bolt or threaded rod that has been hacksawed, guillotined, etc.
It covers threaded bolts or rods from about 6.0 to 18.0mm diameter. It will also chamfer, say, a round bar or ½” diameter piece of concrete reinforcing bar.
It works on mild steel, brass, stainless steel (only works marginally well on stainless steel) etc.
This will increase productivity on a building site but is also ideal for the home handy man.
