Looking for an Aixiz Lens Thread Tap

[Helios]

I called my local hardware stores and none so far can order it.

Its a M9 x 0.5 tap. The ones I do find online are pretty expensive.

I need a regular and a bottoming tap

Anyone know where to get these at decent prices?

I got them on ebay times ago, from a seller called merlintools, and considering the prices you pay them here, they was not too much expensives.

Got 2 of them for 22$ shipping included, and carefully "grinded" one on the top, shortening it for finishing purpose (for complete the thread til the max possible deepth) ..... this require a minimum of attention, but it can be done

Yeah I have heard of doing that to make a bottoming tap.


Actually on second look I see that the one seller on ebay is the merlintools you mentioned and he/she DOES combine shipping so its cheaper than I thought. I will just buy a few of those.

Thanks! +rep - gotta spread the love

Just a thought, it may be cheaper to buy a few m9x.5 bolts. I have made a tap before by simply using a grinder (air or dremel) to cut slits up the bolt in a pinch. I would imagine that if you were making alot of threads you would be better off buying a real one since home made ones probably wear out easier. (I guess that depends on the bolt you use really)

I already bought 2 taps but that isnt a bad idea since aluminum is so soft...wouldnt work as well tapping into steel.

All I can say is good freakin' luck tapping a thread with a M9 x 0.5 bolt.... its hard enough with a tap!

I bought one off a guy in the UK (can't remember the name), it $28 shipped, but it is really good quality, it'll last for ever.... where as the cheaper ones will wear out or snap sooner.... just depends on how often you use it, I guess.

Yeah I've done it a couple of times in a pinch but I never used them any more afterwards so I really don't know how well it would hold up compared to a real tap. I supposed a nice steel bolt and only working with aluminum and copper for heatsinks it should hold up fine, and you generally don't buy a single bolt at once so you would have spares.

Edit: bob, I've never tapped such a fine thread before so I didn't know how hard it was. You probably are better off to buy the tap online, but if I saw the bolts in a hardware store I would definitely buy one and try it.

I work with aluminum storefront doors all day and do lots of tapping for locks and security. If the bolts are hardened steel you might be able to do some. But usually unless you are re-threading an existing hole where the threads were already there in the past. Bolts don't work very well, IMO.

I've even had a cheap (harbor freight) tap twist on me, without breaking, when tapping into steel plates. With aluminum you don't NEED cutting fluid, but it sure helps.
