Višenamjenska slavina sa spiralnim žljebom serije YG-1 F4 od legure vanadija HSS. Alati od brzoreznog čelika dobri su za većinu primjena opće namjene, nudeći kombinaciju tvrdoće i žilavosti za otpornost na trošenje. Obrada crnim oksidom dodaje mazivost i stvara male džepove na površini alata koji zadržavaju rashladnu tekućinu blizu oštrice. Okrugle drške omogućuju korištenje s širokim rasponom sustava držanja alata. Kada se pokreću u smjeru suprotnom od kazaljke na satu (desni rez), alati sa spiralnim žljebovima odvode strugotinu prema gore i izvan reza kako bi se smanjilo začepljenje. Duljina niti 0,6875 inča. Primjena: Dobar za čelične odljevke i otkivke/legirane čelike koji se mogu toplinski obraditi, nehrđajući čelik otporan na toplinu i koroziju/nehrđajući čelik za ventile, odljevke od aluminijskih legura. Izvrsno za obradu ugljičnog čelika s niskim udjelom ugljika/bez ugljika, srednje do visokougljičnog čelika.

Great for Profile Tubing
I used this to tap the ends of my 80/20 profile tubing.

You beautiful Tap... Where have you been all my life!
Forget cheap drill taps and other taps that come in kits. These things ROCK! Drill your proper tapping hole with a drill press or guide first. Since I don't have a drill press with reverse, I use hand held drill with a guide that I made from 3/4" steel plate. Use a good amount of tapping fluid and plow all the way in without stopping! Doing this with a regular tap will snap it every time. These taps eject as they plow foward. The first time I used them I had 32 ea 1/4-20 holes to tap in 3/8" mild steel. I drilled 13/64" tap hole (which is the proper size hole for 1/4-20). The tapping operation was so easy I was amazed. On the last hole I suddenly got scared! I had the thought "maybe I was supposed to drill 11/64" and not 13/64" and that's why it was so easy to tap! After frantically verifying I realized I drilled the CORRECT hole and it was in fact due to these BAD ASS taps that made it so easy. I will NEVER go back to another tap again. Again, I can't stress enough how important it is to use a good quality tapping lubricant and a guide if you are doing this free hand. The aggressiveness of these taps can easily chew up existing threads if re-tracing threads or snap the tap without a guide. And also extra caution should be taken when tapping aluminum or other soft metals as softer materials tend to "grab" the tap and snap (use lots of lube!).

Great tap
Gets trash out of any hole, and threads any hole. Ran this through several engine mount holes and the tool goes in easy by hand and gets out grime, debris, metal shavings with the cool spiral flutes. Cleaned up the threads on the small block, now it's ready to be assembled like new again.

Great Quality
Used this in a Grizzly Hand Tapping Machine to tap hundreds of 5/16-18 blind holes in aluminum. With the proper lubricant this tap will last a long, long time. I ordered 2 more to have just-in-case but at this rate I won't need them any time soon.

It's a good one.
I'm not a machinist using the tool daily, but the threads were to spec and she cut 316 stainless like a hot knife through butter.

Better than straight flute
This thing is awesome. If you're tapping aluminum, you can even just stick it in a drill and do it in one pass with some wd40. I use this to tap several 8020 extrusions.
