Extension Tap: 1-8, 4 Flutes, H3, Bright/Uncoated, High Speed Steel, Standard Hand MPN:R867175

The Extension Tap: 1-8, with its 4 flutes design, is a precision cutting tool ideal for creating threads in through holes of any material that can withstand high-speed steel (HSS) and has good lubrication. It can be utilized in various applications such as machining or tooling to produce fine screw thread at one end of a rod or bar stock while leaving the other end with an unthreaded shank for easy gripping. Due to its versatility, it is widely used across industries including automotive, aircraft manufacturing and general fabrication where high precision machined components are required for assembled units that need accurate threading in blind or through holes without altering dimensions at the unthreaded section. In summary, this Extension Tap provides an efficient solution to creating multiple threads on rods and bars with minimal changes to original size, while offering savings by reusing existing stock instead of cutting new material.
