Most internal screw threads are produced using tapping or thread milling. Tapping is easily the oldest and most mature of these machining technologies and can quickly cut or form high-quality threads. But as many machine shops have discovered, the relative newcomer thread milling is often more cost-effective and efficient. This article discusses when to use one method over the other and offers a few tips on each.

Indexable turning, milling, and drilling tools are often the best choice for productive, cost-effective machining. Learn more about carbide inserts, and how to buy the right carbide inserts online.

Holemaking is the most common of all machining operations. It's also one of the more challenging. Without the right cutting tool, productivity and part quality will suffer while manufacturing costs soar. Here are some tips on avoiding these problems and selecting the right tool for the job.

Hole boring goes hand in hand with drilling. A common machining operation, boring uses a single-point or sometimes a dual-head cutting tool to remove material in a manner that’s quite similar to external turning. Due to deflection and chip control problems, however, boring can be quite challenging without the right tool and knowledge of sound machining practices.

Flat bottom holes are a common feature in a variety of machined parts. Unfortunately, accurately and efficiently machining them can be pretty challenging. Many machinists attempt to tackle this problem with hand-ground drill bits or end mills, with mixed results. The best solution in most cases is to leverage a KTFS-style or comparable high-quality drill bit designed specifically for flat bottom drilling.

If you’ve ever wondered about the difference between face milling and peripheral milling, you’ve come to the right place. This article explores this important machining topic and offers tips on which technique is best for specific applications.

Carbide, cobalt, high-speed steel (HSS)—there's no shortage of high-quality drill bits available, but which one is best for your application? Read on to learn more about drill bit material types and when to use them.

On the fence over what drill bit is right for your machining application? The chances are excellent that one made of solid carbide will offer the most accurate, cost-effective, and productive holemaking solution available.
