Thread milling vs tappingpdf

Thread Mills achieve their thread cutting ability by a method called helical interpolation. Helical interpolation involves simultaneous circular X and Y axis movement combined with an axial (Z) feed and a defined pitch. The helical interpolation tool path makes thread mills versatile with the ability to cut right and left hand threads, internal and external threads, and produce a variety of thread sizes.

If your doing domestic builds, small-medium shops, garden patios, sheds etc SDS+ is great. If your working on a tower-block, building a mall, shop from scratch, SDS Max. It's not just about the bit but the tool your connecting it to. An 18V set of tools are great with SDS+ for example. The battery pack you choose, if using cordless, will also have a big bearing on the quality of the end job. If buying or using corded make sure the voltage is compatible if working of a generator on site.

• Thread mills can adjust the tolerance of the thread• Thread mills can cut material in progressive passes which is better for hard materials• They won’t get stuck in parts if they break• They can cut different thread sizes with the same tool• They can cut odd sized threads• They can be used to back chamfer a hole• They require much less horsepower from your machine than tapping• Thread mills are available in carbide which most taps are not• Thread milling achieves a higher quality thread than tapping because chip removal is more efficient leading to a better result• Most types of thread taps require a hole bigger than the threads resulting in a weak thread. • Thread milling creates a thread with a smaller tolerance for a stronger thread

It sounds like for your application, SDS Plus would be the way to go, given that they are generally less expensive, and you don't have really tough masonry work to do.

Basically I had to use a breaker last weekend, it was clear I did not need the “heavy duty” as I did not have 6” of solid concrete, but the descriptions of the other options confused me.

SDS Plus is an improvement on the original SDS system, but remains compatible with SDS bits, and is now the most commonly seen on the market.

ISO Metric, American UN – Uses a 60° thread angle. These threads are used for general purposes.NPT – National Pipe Tapered is an internal tapered 60° thread used on pipes and fittings. The taper thread will pull tight and form a fluid-tight seal. This type of thread requires a sealant and is not suitable for high-pressure applications.NPS – National Pipe Standard has a 60° straight thread. NPTF – This is a 60° degree NPT thread that is used for high pressure or fuel applications.British Standard, Whitworth – Uses a 55° internal thread form and is often used when a watertight seal is needed.UNJ, MJ – Often used in the Aerospace industry and feature a radius at the root of the thread.

Really I would suggest using SDS Max on the larger projects where you are doing some Demo. SDS Plus is however a lot lighter and easier to move around with, as long as you dont need to go super heavy duty.

In short, sds + is for light duty applications (drilling for ledger boards and light demo), sds max is for people who work with and demolish concrete professionally. I build decks and fences. For me sds + does everything I could ask. Good for breaking up old peirs, drilling multiple large (up to 1") holes in brick or concrete.

Thread milling first appeared about 25 years ago in response to NASA’s need to machine high-quality threaded holes in difficult materials such as Titanium, Hastelloy and Inconel. Thread milling has become a more cost effective method to process and produce threads in hardened materials up to 70 Rockwell, than by the older method of using taps. Thread milling has many advantages of thread making over tapping.
