I have doors that are made from recycled wood. I tried to drill holes through the door with a cheap-o drill bit I had and it took over 10 minutes to get one hole drilled. I bought this drill bit, and it turned that time into 10 seconds per hole. I wish I had purchased this before making the first hole.

Bought it to drill stainless steel shelves. Used the lower speed on my Ryobi battery drill as recommended on the drill package and was amazed at how well it worked.

this drill bit did exactly what I needed it for. I especially liked the guiding nipple at the tip. I have had it for a month now and needed it to drill a large hole into a barbecue in order to insert a thermometer.
