What do we call this drill bit?

Question

I was looking at few videos on "how to screw in MDF". I found the one which I needeed. Unfortunately he didn't mention which drill bit he was using.

Here is the photo of it.

I am looking to buy it from Lowes/Homedepot. Anyone knows what is it called?

in most materials you can get similar results by using a bit larger than the screwhead and drilling over the hole until the scraped-away circle is just slightly smaller then the screw head. Tightening the screw will smoosh the last remaining material into place and leave a flush professional result. They are much cheaper at harbor fright, and the quality is fine for the occasional uses homeowners need. — dandavis, Aug 19, 2021 at 18:34
Thanks. I didn't know about Harbor Freight. Just now looked and it is way cheaper than home Depot. — Rakesh Juyal, Aug 19, 2021 at 19:43
@RakeshJuyal: just be careful, those low prices sometimes come with a serious cost. i.imgur.com/oAOR6gr.jpeg and i.imgur.com/V7tWNgq.jpeg — whatsisname, Aug 19, 2021 at 23:06
@whatsisname That's a good flow chart. Of course, I'd go directly from "Is this motorized" to "buy something else". I figure I'm buying a HF tool for a specific purpose - so long as it is functional for, and lasts the duration of, the task at hand, I'm happy. If I get additional use out of it, BONUS! That said, I've had some really good deals there on tools that have lasted quite a while. — FreeMan, Aug 20, 2021 at 15:16
