Looking for a specific tapered Reamer

[Keresaspa]

Hello dear Friends,

I would like to ask anybody knows where I can get this king of a reamer online, that George showed up in one of his YouTube videos called "Making a "Hot Rod" Pipe PART 1 -- The concept" (link below)

I don't mean the W.L.Fuller Tapered Drill Bits.

The only thing I found is this one, but it seems it has less tapered than necessary.

Hey George, looks like in your video you were using the spiral reamers, but the straight reamers on the mcmaster website
are a bunch cheaper. Maybe the spiral ones are more efficient for opening up a straight air hole? Is there any other benefits for the spiral over
the straight? Are the straight a just plain no-go? (For 20 bucks less?)

I can hear Premel TIAFO-ing in the back of my head...... but not at that price.

Jeremy.

I doubt spiral or straight matters much in our application. I can't recall why I chose spiral.

Straight flute reamers are generally for hand reaming, while spiral flute are generally for machine reaming - faster chip removal, and can be used in blind holes. For reaming in wood, it won't make any difference.

I prefer a spiral reamer, it cuts smoother, especially if using to open up a hole only very slightly. However they are less common than straight flute so I use what I can get.
