Chamfering tool - any good?

[Hood]

Anyone know what the minimum sheet thickness would be so that the guide bearing doesn't fall through?

 

[E T]

According to the specs on mine 3mm minimum.

That should be fine for most things I do so will likely grab one.

 

[Brad93]

Mine should be arriving today.

I can't see them much cheaper than £15 for a box of 10.

Remember that each insert has three usable edges, so that is £0.50 an edge or £1 every time you rotate the pair of inserts on the tool.

 

[Kram]

Yes I know, but if the inserts dont give a good result, that will be 30 edges and £15 wasted.

Perhaps one lf you could do a short video of radius inserts in action..

My £6 cheapy arrived and looks good. Wont have access to my compressor for a few days tho.

The one I linked is now showing as £13.40 with the discount

Looking at inserts, I like the idea of the 1mm or 1.5mm radius type, but do they work well in this? I cant see them much cheaper than £15 for a box of 10.

You don't do any cutting with the insert corners on these machines, it's all cutting using the sides of the insert. So corner rad doesn't really make any difference.
Just make sure you don't buy fine finishing grades, as the edges will fly to bits...

This sort. I realise they look exactly like standard cheap inserts that have had a tiny bit of ground out. I am not sure this chip breaker design was a good choice for radius inserts..

 

[Brad93]

Just received mine.

Not impressed with the finish it gives but it was only £20 so can't complain

Conventional cut gives a better finish it seems

Ordered £13.40, along with 100 aaa batteries for £16 and some petg filament for £9.
The problem with being ill and not able to do much, is spending too much time on here, especially with @Kram influence

ah i see what you mean.

They're not really a precision tool.
Only thing I use mine for is chamfering bits for welding, where finish isn't important. It certainly beats grinding a chamfer.

What do you mean by a conventional cut? Are you using the tool in the proper cutting direction? A roller guide cutter should give a pretty consistent finish.

 

[Kram]

Usually climb cut gives a better finish if you have the rigidity - I doubt these will unless its the minimum cut. The rotor seems to be extremely lightweight and designed for high speed.

I want to open mine up and see if I can convert to brushless, but I dont have a 27mm spanner. I tried in vice, but looks like it may be thread locked.

 

[MattF]

A climb cut shouldn't be necessary. Several lighter passes may be required.

What's the proper direction? Mine didn't come with anything except a parts diagram.

Assuming a clockwise rotation looking from above, pushing the tool away from you with material to the left of the tool would be a conventional cit

 

[Kram]

Thats the insides. It had threadlock and needed a bit of heating. The 3" sweedish pipe wrench had no issue turning the body with nut in vice. Tiny bearings in the black steel rings. Odd design but I know little of air tools. Shouldnt be too difficult to make it a brushless tool.

Anyone tried the radius inserts yet? Please?

 

[Hood]

Got mine this evening so nipped down to the workshop to try it. Seemed to work ok, obviously the smoother the face the bearing runs on the smoother the chamfer. I tried in on some aluminium and some stainless and it seemed to be a better finish in the stainless.

The radius is ok but quite hard to set the correct depth, pic showing the radius on the outside and chamfer on inside of some plasma cut alu.

 

[Hood]

Oh also broke one end of the torx key, seemed very brittle, have ordered some cheap torx drivers as I didn't have any small enough, think it may be a T4 or T5 and smallest I had was a T6

Same as with a router. Counter-clockwise on external edges, clockwise on internal edges, if memory serves.
