Review on Precision Carving With SpeTool Ball Nose Router Bit - 2.0Mm Tip Diameter Carbide End Mill For Woodwork And Metal Mill 3D/2D Work by Mark Young

This is a great tool bit. I used for grinding off 3 steel wheel studs and lug nuts on two Jeep wheels where the lug nuts were rusted solidly in place. The bit also allowed me to easily mark the center of the wheels studs so that I could drill much of the stud away before finishing cutting through the stud and the lug nut. I was able to remove the frozen studs and lug nuts without wrecking the alloy wheels. The alternative would have been to use a cutting torch, ruining the wheels. It cuts well, and is not easily broken.
