|Jrod-13||Has anyone else used century taps? I've bought quite a few over the years, and have been pretty satisfied, they are made in japan.|

It is night and day difference between Irwin and a quality tap. My bolt supplier brings me Champion and Alfa cutting tools, I'll be replacing the Snappy with them as I break them.

I like spiral point taps. Beefier cross section and seem to cut real well too.
|09-20-2019 07:47 PM|
If I am cutting new threads into something I usually buy something a bit better from MSC or other tooling supply places.

Also these t-handle tap wrenches from HF are actually really good for the smaller taps. I like using that style of wrench over the big t-handle as it gives you a better feel for the smaller taps.

You can get the same sets on eBay for cheaper. I have both metric and SAE. Tap wrench is cast aluminum and QC isn't that great. I broke one of them because there was massive porosity at one of the corners. Tapping hard steels in coarse pitches will wear them out decently quick. Other than that they're great. You can't beat them for the price.

|H8DWINGS||4 year old thread bump. Harbor freight $85 set worth a shit? Tool truck $200+ sets worth a shit?|
|09-25-2015 08:21 AM|
this is what i'm wondering as well. I won't be using it too frequently, but i'm not exactly close to the tool store either. I'd hate to have a tap break and im SOL for a few days.

Where does Irwin fall on the quality scale ?
I bought the Irwin fatty set from Roark supply years ago and they have served me well for occasional use.

|supernatural||i ended up buying the irwin 75 piece off the tool truck. my tap set didn't come in time, and i really need to get my steering box tapped. oh well, i got the big one. its just money right?|

I buy the Mastercraft (Canadian Tire) tap & die sets when they're on sale 50-70% off. I'm covered up to 5/8" & M16, with duplicates of most everything under 1/2" & M12. I know they're chinese stuff, but I get good mileage with responsible use and tapping fluid.
Now I think its safe to lay off and buy just individual taps as I break them.
|09-21-2015 10:05 AM|
I had Snap-On taps/dies before I bought the tool truck.
I'm of the opinion that 90% of the problems folks have with taps is due to poor drilling of the hole or poor technique.
I don't break many taps (but when I do, it's a part that the stock was expensive and the work extensive-LOL). I do however dull a lot of taps in the common sizes and for that it's nice to have them replaced under warranty (my Tool truck guy never questions MY warranties-LOL).
If you expect to dull thread cutting tools, the tool truck might be the way to go, but stay off the Harbor-Freight truck or Wal-Mart trucks!

Run them by hand with good GL5 hypoid gear lube for oil. They seem to work very well, and at least for 4-40 the drill size is a fractional one rather than a number or letter.

|D60||^^^^pfft, Delrin's one of the better ones. Try it w UHMW, your hour of deburring would double LOL. There's another Delrin piece where they call out a 0.010 radius on an edge. Uh huh, that's code for "hit it w a needle file and call it good." At least Delrin kind of files, UHMW just kinda bounces off.|

|speedfreak78||Anyone use form taps at home? Not quite as easy to use by hand but a much stronger thread. I like em for the fact there's no chips.|
|09-20-2015 07:58 AM|
M3 in delrin..lol.what a PITA. Drill an undersized hole you can run a screw/bolt into, it'll thread itself...lol I worked at a place we made delrin pump housings..20 mins of machining, an hour of deburring. I had a deep hate for delrin after that job.
|09-19-2015 10:58 PM|
Another cheap bastard tip, toss a chainsaw sharpening wheel (3/16" or so thick, dressed to a radius) into a cheapo bench grinder, and run it down the flutes on the cutting side, takes about 30 seconds to make a dull tap cut like brand new again.

|BigBlue&Goldie||I wouldn't waste your money on truck brand tap/die sets as most of them are just relabeled carbon steel Irwin/Hansen sets. Like others have said, go on ebay and look for a USA made Craftsman HSS set. As you break or wear out taps, replace them with a higher quality from MSC or McMaster.|
|09-19-2015 01:01 PM|
I'm pretty happy with my big Craftsman set, but when they do wear out or break, I've started buying the 3-tap Irwin sets on Amazon. It's about the same price for a taper, plug, & bottoming tap as a single taper locally, of any brand.
...and they're made in USA.
|09-19-2015 12:35 PM|
Slightly related to tapping, one of my least favorite jobs involves tapping a shallow, blind hole M3x0.5 in Delrin. Shit, it's hard to know if you've bottomed before you strip out the plastic. But I learned the hard way on a part that I already had many hours in, and developed a feel for it very quickly after that LOL
|09-19-2015 12:11 PM|
Look at a decent one and it'll have next to no relief angle at the cutting edge, so that it snaps the chip off cleanly without wedging it between the hole and the tap.
