Deburring

[VicParticipant @vic]

Don’t underestimate how well these work. I did and feel stupid now for not buying one sooner. I actually bought two last year, a Noga and a Swisstool version as it was cheaper to buy the second one with the extra inserts.
Deburring cross holes in shafts was always a problem till I got one.

Edit: I’ve just got the basic deburring tools with a variety of inserts.

What a ghastly video – can’t even turn the blasted thing off!

Still, I can vouch for the standard deburring tools, which have been around for years.

I use one of these. Nova are a better brand but much more expensive but comes with a number of different cutter. Just drag the tool over a burr and it is sheared off.

Just click on the video and it will stop.

No different to any other Youtube Video, must be an operator problem.

The type I use a lot are the small “rotative” ones that are great for small holes for fixings etc where the “hook” type are  a bit big. This is the set I use, Tracy also do it but out of stock with them

No Jason – the video is in an irritating, patronising, gimmicky style better suited to advertising fashion-accessories to teenagers on Tik-Tok than informing engineers properly about a workshop tool. The “Close” symbol did not work – but why would the advertising-agency want it to work?

The deburrer I have has only the hook blades, and those will cope with holes down to about 3/4″ dia. Below that I usually use a drill or countersink bit, or a tiny scraper. (A twist-drill can dig in and give an irregular edge).

What the video didn’t show is that if you are deburring a edge from an end it’s normally necessary to start part-way along then finish the first end in the reverse direction.

They are though, effective tools.

You don’t need close to “turn it off” as said just click anywhere on the video or click the “II” pause button and move on.

The close does not work on several forums I use, something to do with how the forum software embeds the video.

It’s a promotional video, I’m sure they also have technical videos or a visit to their website will give an engineer all the  technical details they may want.

I first saw the Noga deburring tools about 40 years ago. I should have bought one then.

I have just looked at the video just to understand a deburring tool. Thankful I had no problem turning it off.

I have never owned such a tool. Why buy one when a small scraper or needle file works just as well? They are the sort of things one bought at shows when one had a little bit of cash remaining.

Do I really need one? Or even YouTube.

JA (living in the past?)

I suppose if you are sitting on a production line with several thousand holes to de-burr a day then the ease of which one of these can be used will make your life easier and also speed up the process.

I’ve had them for maybe 30years, don’t use it all the time but when I do it is quicker and easier than a scraper or file. being able to take the burr on a 4″ hole in maybe 2 seconds and have a nice even small chamfer all the way round has got to be better than other methods.

These days CNC machines will run a separate de-burring path with a chamfer tool which takes the manual part out of the job, they will even do the bottom of holes and a reverse chamfer all round the bottom so it does not need that op when cut from the parent stock or the parent stock faced off.

I have to say that I tend to use my GHT graver rest and a graver if the part is on the lathe but if the part is in your hand I do use a Noga tool but they are ground for right handers so I have to swap hands to make them work properly as I am a dedicated southpaw!

[JasonBModerator @jasonb]

You can get blades for lefties

[bernard towersParticipant @bernardtowers37738]

Ahh that I did not know, thanks Jason.
