![]() I will post how it goes and maybe take some photos of the parts when I am finished if you guys are interested in seeing them. Thanks to everyone for the kind knowledgeable advice here. If it works half as good as they are boasting I will probably buy these taps from now on as most of what I make is aluminum. Balax's website says that their taps can last 3-20 times longer on average than other taps. Altho what seems like a long time to me might be a days work for you guys running production parts all day long. From what I understand the roll form taps take LESS HP and actually last longer which is hard to believe since the spiral flute taps I currently use seem to last a long time in Aluminum. ![]() I HAD been using some spiral flute taps in aluminum and they work TONS better than the typical hand taps I used to use. Produced out of high-speed steel HSS or hardened carbon steel, where the former is much more robust and used for. I like the idea that you get a smoother better thread with the roll form. Taps and dies cut metal and other threads. This is a really non- precision part but I am hoping it will be something the guys asking for it can sell a bunch of and I want to be able to offer it for a good price and be able to make them fast and accurate. Hard Chrome A surface treatment in the form of a thin hard chromium layer deposit. Improves Performance in stainless steel, steel forgings, tool and die steel, and hot and cold rolled steels. Black Oxide: Helps retain cutting fluid in the working portion of the tap. Wish I had a large VMC but I am working on that. For tapping hard steel alloys, titanium, exotic metals and hard copper alloys. My machine is kinda small and has a 3hp three phase spindle. I will probably just use the coolant now since some of you remarked about it working well. From easy to ambitiousLearn how to play 20 Metal Guitar Riffs on guitar.Get the tabs and sheet music on Patreon. This is my first Roll form tapping operation and I wanted info to help me get it right. As I said I am kinda new here and not really sure about this. Maybe we should spring for a new $10 tap before loosing a very-close-to-finished part.Ģ500RPm huh. ![]() ![]() We probably use an excessive amount filling a 0.600" deep hole to tap 10-24, but we have tapped hundreds of holes with one tap and no failures. Even Acetone and MEK has a hard time cleaning it off, well not really, but it never seems to want to come off easily. Oh, all this in 6061-T6.ĭown side of Moly-Dee is the mess, don't get me wrong, it works wonderfully and we use it on a T316 stainlees job with Balax form taps, it's just kind of a bear to clean off. We still have one hole in a job that is a blind hole and use a sprial fluter.what a pia to have to pull the chips off after every batch.at least it's only 4 holes per cycle. The holes are not very deep so even our Mazak horizontal barely gets to speed before reversing. I do not recall the tapping speed right off hand, but I'm thinking 2,500 rpm on 1/4-20's through M8's. Pete, are you running this on a machining center with coolant? We run our Balax Threadfloers (their tradename for thread foring taps) with a fairly low concentrate of coolant (~6% Qualichem semi-syn + water). ![]()
