How a Recoil Wire Thread Insert Works: Recoil wire thread inserts are rolled from high quality stainless steel wire with a diamond shaped cross section, wound to the shape of a spring thread. Once the insert is installed into a tapped hole, it provides a permanent and wear resistant thread in the parent material that is stronger than the original thread.
Recoil inserts are greater in diameter than the corresponding tapped hole and compress as they are installed. This allows maximum surface contact area with the tapped thread, safely and permanently anchoring the inserts into place. 
The kind of hole to be tapped has much to do with the style of tap that’s best suited. Some holes go all the way through. Others, while not through holes, still are relatively deep. Some are quite shallow, little deeper than diameter. Each of these three kinds of holes through, deep-bottoming blind, and shallow bottoming, has a tap or group of taps best suited to requirements.
Rapid Removal… extensive profile available.
The double cut bur allows for rapid stock removal in the harder materials. The chisel tooth pattern not only minimises tool chatter but reduces the chip to a granular shape, in most materials, thereby reducing or eliminating the sharp sliver chips that are normally experienced. This chip reduction also helps eliminate loading of the flutes.
An improvement in tool control will be realised as the double cut tends to reduce the pulling action of the main flute pattern.
Newly developed hardwearing super alloy materials call for innovative tools for effective and efficient machining. Sutton Tools’ latest product release—the Black Magic Carbide Drill ranges—provides the ideal solution for high-quality drilling of the latest materials found in the aerospace and oil & gas industries.
Sutton Tools has launched its new range of Black Magic Carbide Drills, aimed specifically at stainless steels and super alloys—such as austenitic stainless steels 304 and 316, duplex grades, and inconels 718 and 725—in the aerospace and oil & gas industries.
