Got My Outside Chamfer Tool Today

[JoeLee]

And I have to say that I'm not impressed at all by the workmanship or the finish it leaves.

They must have ripped through those slots as fast as the cutter could move through it. Never even bothered to deburr the edges. The cutting edges are finished the same burrs and snags.

I did a couple test cuts with it.

The chamfer cut is left all scored with radial lines and the edges of each side of the chamfer are left with burrs. It doesn't leave a smooth finish, in fact it more or less plows through the material leaving windrow burrs on each side. I could do 100 times better with a regular late tool bit.

It's supposed to chamfer down to 1/4" dia stock but won't go much below 5/16". When I tried to chamfer 1/4" it cut more or less of a step on the edge, all burred.

Maybe I got a bad one or should try a different brand. I really didn't expect anything this bad. I thought it would be finished as nice as all my counter sinks are.

That is horrible, who made that thing? A blind Chimp with a Hatchet and Fine?

Looks like you have choices. Two of them.

Get in there with a type 12 wheel and clean that up, or take it up with the supplier.

The only thing that got deburred was your wallet. That is disgusting.

It's made by HTC Tool. Made in USA. Michigan I think.

If it came from china or india and the price was $10 I could see it.

It's going back.
I called the company earlier today. The guy apparently pulled one off the shelf and looked at it. I told him this thing looks horrible. I can't remember the word he used, but it was something like beauty is in the eyes of the beholder, something to that extent. Either he's blind or I got a bad one, which means there is a whole bad batch of these that look exactly like the one I have.

I can see how thy are made, CNC cut, bar stock feeders feeding stock as fast as they can plunge the cutter in.

Tomorrow I'll post pics on how it cuts. I have some 12L and brass I'll use.

HTC, usually has good stuff. That cutter looks like it went through heat treat and was never ground.

Yes, that's exactly what it looks like, weather it was deliberate or a mistake / cost cutting measure is yet to be known.

I have a few counter sink inside chamfer tools and they are all ground, even the flutes. Grinding wouldn't leave a burr.

^{how fast you running ? I would be at 150 or less especially on stainless..}

Running in back gear as slow as it'll go. Any faster it starts to chatter.

So I open the thread you made about these cutters you have been sourcing.

Sweet, he got them. I see the picture of the cutter and thinking maybe that is some new type of grind. Cause its ugly.

Oh, maybe they accidentally sent you a pre-grind cutter (bet its over sized). If not I am surprised. I have worked with HTC, good folks. JR

Edit: After looking at the photos again it looks like a "rougher" that didnt go through the entire grinding stage.

Looks like it came from India

[Paul Alciatore]

[dian]
