Anyone see this hole saw?

[cgallery]

I just saw an ad in a promotional copy of Wood Magazine that I received.

It is for a wing-type hole cutter. They call it "The Hole Thing" and mention that it "sits at a 15-degree angle."

Here is the web site:

I can't figure out why the 15-degree thing matters. The ad and web site mention it, but don't explain why it matters.

Anyone have any ideas?

Will it make a tapered hole/plug?

No the cutter is still 90 deg. Looks like a marketing thing to me. I have one that straight that I have had for 20+ years. I have used it to make wheels for wooden vehicles, works great. There is one thing that comes to mind while wtiting this is at15 deg the cutter is less likely to move during a cut.

My guesstimate is that it tips the actual cutting edge into the material to give more clearance. If there was more of a bevel on the cutter, and the cutter was not at the angle, the cutting edge would be more fragile, and get dull faster.

probably lets you use a shorter cutter since it brings the cutter down lower.
Less moment arm on the cutter to break it and allows you to sharpen it a few more times.

Don't they call that a beam saw or something, not a hole saw?

I think a beam saw is similar to

a circular saw. Been many years since I've heard that name.

I always called mine a fly cutter. At least I know what I mean when I talk to myself.

yeah fly cutter, that's the term i was looking for.

[Tom Slick]

It operates similar to a fly cutter but a fly cutter is a surfacing tool, not for making holes.

Mine was packaged as a wing cutter.

This might be a surprise, but it's actually called a "circle cutter".

I just call mine "the circle thingy."

In my shop it's called a "knuckle-whacker" -- usually with some preceding expletives.
