MaxxTor Impact Power Bit Hex 1/8" x 49mm - 10 Pack

Would recomend

I do not use this bit for impact. I ordered it for a very specific task which is working on set screws for shaft collars on damper actuators. I have low clearance and significant torque to apply. This bit fits perfectly not only in clearance but within the screw-head. It is a snug fit without being hard to insert. I purchased a 10 pack of these and handed them out to my co-workers.
