Hi Dean,

The gables are painted steel. Not galvanised, so every 10 years I have to strip off the rusty areas and redo.

These days I cold galv before the top coat and the rust is getting less as I keep adding the cold galv to more areas

Dirty job rubbing it back.

Can you weld with a 3800 watt generator ?

I thought you needed about 7 KVA.

I don't know for sure but the mig only has a 10 amp plug so wont need too much. Must try it and find out.

Not long enough great for polishing, but I wouldn't use them for paint removal...

I tried the mig welder on the generator today and although I could hear it loading up seemed to work very well. Only did a quick weld on the end of a bit of galv angle but the weld looked good.

Next time I have the generator loaded on the trailer I will take it around to the shed and try the arc welder. That is only 130 A so will probably work as well. It would be better to use the arc for fixing the yards/crush but it is a bit harder to move even tho it is on wheels.

They might be OK, but I learnt my lesson with cheap centre drills (in small sizes) a while back.

If the HSS is brittle it's a right pain in the butt when the tip breaks off and you can't get it out. Can muck up hours of work or stuff the job when you have to reface/reduce the end to remove it.

Trouble is you don't know what's good and what's not until you put them to the test.

I will stick to known brands in future.

Yeah, for the same reason i only buy good center drills now, normally dormer. I think a no.3 costs me about $9 but i am yet to break one. I just drilled all the holes in my dividing plates with one end of one, all 525 of them, and the bit doesn't even look like it has been used.

Yes I'd guess they would be rather low quality . But OK for using on aluminium and brass .... maybe Mike

Look carefully at the pictures. The seller is very honest, it is a nice set of sharp pictures showing great detail. Maybe it is just me... but to me the grind finish looks too coarse. Not the sort of finish that I would expect on a quality tool. And that cutting edge, is it as sharp as it should be? I enlarged the picture, and I think I can see a burr?

Then the description:
"Suitable for processing: Ordinary steel, iron, copper, aluminum, wood, plastic and other materials with high hardness can be used".
.... there is no mention of stainless steel?

I guess it depends what you want to use it for. These may be perfectly fine as spotting drills into sheet metal. Chris

Look carefully at the edges, it's not finished well. The burrs are not removed, doesn't look very sharp at all. If you know how to sharpen a drill, great buy but many of these cheap center drills are not center at all.

For that price - why not. Will use them on Al and brass.

For that price, steer clear. Unless you like digging bits of hss out of your work.

I got a pair of solid carbide centre drills quite a while ago and they are great, still perfectly sharp too after doing literally countless holes. Expensive but well worth it.


I recently got a 10mm drill from McJing with brazed carbide tips. These are a good buy, i will be getting a range of sizes i think. About $10ea.
It was no good out of the packet but after a sharpen it is unreal. Ive only sharpened it once since then and it is my standard pilot drill in steel or alloy now, done 400+ holes at a guess.

Good idea. I will look into this.

If as CBA mentioned the HSS centre drills are specced as suitable for stainless, then I would consider them.

I have quite a few cheap HSS slot mills specced for stainless and they are excellent.

Get yourself a pack of German made Jigsaw blades for $7 each at Aldi supermarket. There are 10 different blades with various teeth profiles for different jobs. 7 for wood and 3 bi-metal for metal.
