New tool thread

For drilling, tapping, rethreading tools use only USA, Japan, German or other first world COO, cheap tools can cause massive headaches.
And here I was only chasing threads. Not even doing anything complex…. Point taken!
 
Took the Lang chaser out to try on the exhaust manifold holes on my 300D.

The Facebook marketplace barely used cheap Chinese one could only thread in about three turns.

The OE studs that were removed thread in the while way.

The US made Lang ones thread in fully as well.

Lang is on the left. Lesson learned. Don’t trust anything of consequence to the cheap achinese tools many folks love to buy.

I've had that lang set for years and use it all the time for chasing threads, one of those tools you wonder how you went without it.
 
Any suggestions for a good tap and die set for diy?
It depends on what you need to do DIY or pro still need quality tooling if tapping new holes and want a precision fit. I don't own any "thread chasers" I either make one or use inexpensive Irwin carbon steel taps. These are what I use, they are not high quality taps or dies but good enough for general use.

These are a few of the taps I use to actually cut new threads, all are HSS and high precision, use one of these and the Irwin and the difference is night and day. IMHO figure out what you need metric, SAE, and buy the sizes you need most, for metric M6, M8, M10 in various pitches are the most common, occasionally I need M12 and M14x2 for specific jobs. Look on ebay, Amazon for brands like Morse, Cleveland, Kodiac, Dormer, OSG, Guhring, Widia, Greenfield (old), and many others. Buy the basics you need and add on as needed.
Look for high quality tap and die holders, Starrett makes some really nice stuff and used can be found a reasonable prices.

Having a solid assortment of rivets ensures I won't have a job that requires pop rivets for the next seven years.

I also grabbed a flex head cutoff tool. There's several variations on the market with the M7 being the least expensive. AFAIK, M7 air tools are decent and it's Taiwan COO. I actually go out of my way to not use air tools but I believe in options, so I wanted one but didn't want to spend a lot.

Let me know how you like it, and if the air filter loads up too much. I might be interested in one at that price.
Will do. I'll probably never let the air filter get too dirty. I always clean my saws between uses so they never have a chance to get too nasty. A lot of the videos I've watched on YouTube make me sad for how some people abuse their saws.
