I put this in Gen Auto because it involved my knob. :wiggle: I have a Titanium shift knob that I want to tap deeper, and all we have at the shop is High Speed Steel taps, hence, I need a higher grade tap to tap this about 0.200" deeper. Anyone have a higher grade tap I can borrow for a day? ---

why do you need a higher grade tap? Just use a 4 flute and thread a little bit at a time and back it out… this prevents galling. Other then that… you will be fine. is this the mammoth chunk of titanium I gave you?.. you’re going to reduce it down to a shiftknob? I have some smaller diameter pieces… if you want less to machine down. Titanium is sexy, and i know your knob will be to 😉 the reccomended rake angle for Titanium is 5°-10° and steel is 5°-12°… so your steel taps are within spec. EDIT: A little more info then you need… but i’ll provide it anyway Titanium has a low specific heat and tends to wed onto the tool material, so oxide coated taps are recommended. The reason why I recommend a 4 flute tap is to minimize the contact between the work and the tap… limiting galling. With this, a higher grade tap isn’t needed, just a coated tap, which you are likely using anyway. ---

> [@walter](#): > > Order it for work. I thought about doing that, but the cheapest that I could find for a one time only tap was about $40, and someone might get alittle curious as to why we ordered it. As for you LAFENFAG, I tried using a 4 flute HHS stap this morning, and I was able to cut in very small increments, but when I was backing the tap out, it was chattering like 9 year old girl. I was honestly afraid tha I was going to break the tap in the hole. I also tries using a TON of oil in the hole to make it alittle easier, but it only reduced the chatter to a 12 year old girl. As for the Mammoth chunk, because of the features already machined into it, it really wasn’t all that large of a piece. Also, it has already been made into my shift knob, :wiggle: and it is :pimp: as all get out. BTW, we have coated taps, but by Murphy’s law, we don’t have one in M10x1.25… So, maybe I should chage the title to WTBorrow: Coated M10x1.25 BOTTOM tap. When it is all said and done, want to polish my knob Josh? ---

If you can help me out, I would greatly appreciate it. I could pick it up from wherever you are. I will probably use it over the weekend, and return in to you by Monday. Like I said, I only want to borrow it just to tap one hole deeper. Josh, if you brush by knob, wouldn’t that lead to chaffing? ---
