I install Central Vacuums, and use this bit everyday. I was impressed from the day I got it. The two cutting heads make a HUGE difference. No kickback, stays sharper longer, the list of positives goes on and on. I also own a Milwaukee 2 1/4 self feed, and there is nothing to compare!
Heavy built and durable. Needs a powerful drill and a strong hand! More strength than i needed for my project.
Fast delivery, sturdy construction, came with everything. Most of all great price.
