Thread forming taps for aluminum11/22/2023 Advantages and Disadvantages of Forming Taps and Cutting Taps However, in many instances, cutting taps are a reliable option for creating internal threads. This makes them less ideal for some applications, such as blind holes, where chips can get trapped and cause issues. The use of cutting taps results in chip production, which can impede the tapping process. Although thread forming taps are more versatile in terms of material compatibility, cutting taps still offer a wide range of applications. They create internal threads by removing material from the tapped hole. Cutting TapsĬutting taps are tools used to cut material and produce chips. This is important because cutting taps produce threads by cutting material, which can cause chips and debris. Lubricant grooves in forming taps enable lubricant to be supplied along the longitudinal axis of the tap, avoiding the creation of a hydraulic seal and “lock” which could otherwise deform or damage the part due to pressure buildup inside the part. Using a thread forming tap, also known as a roll tap, is an efficient and reliable method for thread forming in various applications. Additionally, the lack of a cutting edge ensures that there is nothing to wear and become dull. They offer a long lifespan due to their fluteless design, providing the necessary rigidity to avoid breakage. Thread forming taps generate threads that are significantly more robust than those produced by cutting taps. This means there is no need for flutes to evacuate chips. Understanding the characteristics of forming and cutting taps is crucial for selecting the right tap for your application.įorming taps, also known as roll taps, form taps, and fluteless taps, create thread forms by rolling material rather than cutting away any excess material. Roll taps are often chosen over conventional cutting taps for smaller or larger holes, trickier materials like stainless steel or exotic materials, and swarf issues that lead to tap breakage.
