#FORMING TAPS FULL#

If you need strong threads in your parts, form taps are the way to go.įorm taps are stronger and will last longer than cut taps. That brings us to the next advantage the threads are much stronger because they are “formed” into place. A form tap does just that, it “forms” the threads in the hole with pressure, as opposed to “cutting” threads. What’s better about form taps? Well, they have several advantages over cut taps that will make you want to use them more often. Since this type of tap “cuts” threads into the hole, you can get away with using various coolants and mixtures without breaking tools, especially on soft materials like aluminum. You also won’t have to worry about running into anything unless your table or fixture is under the hole. This equates to much faster tapping cycle times.Ī cutting tap is great for thru-holes, as you won’t have to dig into the hole to pull out the chips.

It allows you to tap at higher RPM without putting so much load on your spindle. Rigid tapping is a very useful option on newer CNC Mills such as a Haas. Depending on your machine’s capabilities and what material you’re running, you may only be able to run it at 200-300 RPM. They are easy to use just drill the hole with the correct tap drill size, making sure you go deep enough so that the tap will get enough threads, then run the tap into the hole. Tapping with cut taps has been the most popular for decades because that’s what there was available. A cut tap also has clearance cut around the tool so that chips will move out of the way and not break it.

A cut tap doesn’t have a full thread until about the third time around, while a form tap looks the same from bottom to top. After using both kind of taps for a while, you’ll see the difference in looks right away.
