Cheap gear cutters from China

I have just received a set of 8 gear cutters from China via ebay and I must say they look rather nice. I have wanted to try gear cutting for a while but could not bring myself to pay up a lot of money for something that would not get a huge amount of use.

I took a punt at the Chinese ones, not expecting anything great, but I must say they do seem well made. I have not used them yet so this is just a first impression, but at about £38 for a set of 8 cutters they do represent good value provided they cut well.

The workshop is a bit cold at this time of year so I will have to wait a bit before trying them out, but at least I can sit in the warmth and look at them!

I has a set of gear cutter, Module 1, 0.7, 0.5 from Alibaba, really cheap to buy. I'm satisfied the quality of the gear cutter, precise as i can see when i created the gear wheels.

I forgot to mention the ebay number which is 162447654385

I bought set of 1.25 mod cutters from banggood. I have used them to cut a set of gears for my Mastiff powered Charlatan I'm building. I am really pleased by the quality. the only problem being me in counting the holes on the dividing head plate, must remember in future don't include the hole the peg is in, as I now have two practice gears that don't quite mesh.

As rule in the dividing plate for indexing head: counts of hole + 1 hole for pin As usual newbeginners did fault when they count the hole with pin in the hole to example 5 hole instead 5 hole + 1 hole for pin at dividing plate for indexing head.

I bought a couple of similarly priced MOD1 cutters and although they did the job they were starting to loose their edge after about 70T each in 1/4" wide steel so you get what you pay for.

I has the gear cutter same factory as your gear cutter where there is marked on gear cutter: 上工 (Shàng gōng).

That is interesting Jason, as long as I stick to aluminium they should be fine for letting me try out gearcutting. They do also look quite easy to sharpen, so even if they do blunt quickly they can be touched up to give extended service.

Thanks for that link Jens Eirik, it looks as if the cutters are made in a decent factory rather than some backstreet outfit.Have you tried cutting steel with your cutters, and if so how well have they stood up with regard to wear?

Doug

Tried to cut in steel, cutter seem fine. I'm cutting mostly in cast iron, brass and aluminium. Use right rpm and cutting fluid to keep cutter cooled and sharp enough. It's not difficult to resharpen the cutter if worn out.

Doesn't work for me.

Try just copying and pasting that number into ebay search [it’s not a hyperlink]

... works fine on ebay UK

The simple rule for sharpening them is always sharpen the face so it remains in line with the centre. This means you have to rotate the cutter to grind more off, rather than moving it.
