Comes with forged wrenches, not stamped steel. Nice gesture. Very smooth running with no measurable runout on straight 1/4" shaft. Tested with a cut-off wheel, left a very smooth surface. Adjustable speed is accurate but can be accidentally shifted. A strip of tape will secure it in place. Go to Cutting a hole in 18 gauge cold rolled steel with a 1/2" rotary cutter. Worked like a champ, like a router, but was meant for this stuff. Soft start is ok, safety isn't needed. When the switch is on and the machine is not connected, the engine will not start.
