9/3/2023 0 Comments Form taps for hard metal![]() Contact us anytime and put our carbide taps to work for you. So, don’t let difficult materials give you a “hard” time. Solid carbide cutting surfaces are bonded onto a high-speed steel body to provide the best of both worlds durability of carbide with the “forgiveness” of a steel body and shank. Higher cutting speeds, greater tool life, and reduced downtime from fewer tooling changes translate into reduced machining costs.Īn alternative to costly larger sizes is our line of CarbISert® Taps. Array of custom High-Speed Steel taps available The Why of Carbide TapsĪlthough initially more expensive than HSS taps, significant savings can be realized, especially in long-run jobs. Also if it has 2 or 3 flutes I think it would be. I need one that is for tapping ferrous metals. What sort of tap should I get many of the ones I found on MSC say they are for cast aluminum. I dont have a rockwell hardness tester but its as hard as a regular high speed tap. Carbide STI (Screw Thread Insert) tapping of these materials has become commonplace in the aeronautical and aerospace industries. Here is my question I need a Carbide tap. Coolant holes through the taps are an option for flushing chips out of the holes on the most difficult materials like some of the tougher stainless steels and space-age alloys. Modern CNC equipment is ideally suited for carbide applications. ![]() Hand tapping is generally not recommended. Rigid tapping and spot-on alignment are critical to avoid breakage. Not to worry, however. Machining with carbide does come with some “do’s and don’t”. For increased performance and life, we can customize tools with a full line of surface coatings such as TiN, TiCN, and TiALN. A wide range of styles and features are available, including straight flute, spiral flute, spiral point, and forming taps. We offer carbide taps in UN and Metric sizes as well as straight and NPT/F Pipe and STI Standards. Our carbide taps are American made from high-quality C2 micro-grain carbide by highly skilled machinists on state-of-the-art equipment, and are backed by decades of experience from our support staff. Array of custom High-Speed Steel taps available What Carbide Taps to Use Use uncoated high-speed steel taps for small-scale tapping jobs. Uncoated carbon steel taps are for thread repair and occasional tapping. They have a square shank thats compatible with tap wrenches and tap holders for drill presses and milling machines. With the appropriate style for the application, tool life of carbide can be 520 times that of HSS, with the added bonus of superior accuracy. A prerequisite for using forming taps is a tool break elongation of at least 8 and a maximum tensile strength of up to 1,400 N/mm2. These taps are for use on most metal and plastic. While high speed steel (HSS) taps have a practical top limit of around 35-40 HRC before tool life becomes severely limited, carbide is often used in materials with hardness up to 65 HRC (the ones that chew up HSS in no time). Consider a change from steel taps to carbide taps. How do you overcome the difficulties of making parts out of challenging raw stock? By using a tool that’s even tougher. They’re hard to machine, hard on tool life and hard on production cycle times. Highly abrasive materials like cast iron, polymers, glass filled polycarbonates, and some cast aluminum are called “hard” materials for a reason. ![]()
