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. If your equipment doesn’t exactly meet the pre-drill requirements, you can always mill or interpolate the right pre-drill size. I HAD been using some spiral flute taps in aluminum and they work TONS better than the typical hand taps I used to use. For form threads: Pre-drill Thread Diameter Thread Pitch/2. I like the idea that you get a smoother better thread with the roll form. 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. Wish I had a large VMC but I am working on that. 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. This is my first Roll form tapping operation and I wanted info to help me get it right. Available in straight and spiral flute, spiral point, and forming. As I said I am kinda new here and not really sure about this. For high-performance threading, select Kennametal’s High-Speed Steel taps. Maybe we should spring for a new $10 tap before loosing a very-close-to-finished part.Ģ500RPm huh. For start-to-finish tapping of left-hand threads, these sets include one taper-, one plug-, and one bottoming-chamfer tap. These taps are for use on most metal and plastic. 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. Use these taps on hard and abrasive material, such as heat-treated metal, nickel, and fiberglass. 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. From easy to ambitiousLearn how to play 20 Metal Guitar Riffs on guitar.Get the tabs and sheet music on Patreon. ![]() ![]() 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).
