Hss Mach Reamer Z6 5.4 H7 L/h Spiral

Product information

Maykestag HSS-E NC machine reamer 5.40mm H7 left-hand spiral Precision 5.40mm H7 NC machine reamer manufactured from HSS-E, featuring a left-hand spiral, six cutting edges and a 6.00mm shank for standardised high-precision toolholding. The Maykestag Code 3080 is an HSS-E NC machine reamer designed for precision finishing of existing holes. The tool features a left-hand spiral and six cutting edges for controlled and consistent hole finishing. With a 5.40mm reaming diameter and H7 tolerance, it is designed to produce accurate finished holes in professional machining applications. The tool has a 6.00mm nominal h6 shank and an NC-compatible design similar to DIN 212, with a straight shank diameter suitable for standardised high-precision toolholding. What is a machine reamer? A machine reamer is a precision cutting tool used to accurately finish an existing hole to a specified diameter and improve its dimensional accuracy and surface finish. Unlike a drill, a reamer is designed to remove a relatively small amount of material from an already prepared hole. Machine reamers are commonly used where consistent hole dimensions are important. Product highlights • HSS-E construction: High-speed steel with cobalt alloying for demanding precision machining applications. • 5.40mm H7 reaming diameter: Designed for precision finishing of existing holes to H7 tolerance. • Left-hand spiral: Left-hand spiral geometry provides controlled chip movement during the reaming operation. • Six cutting edges: Six-flute cutting geometry supports consistent and balanced hole finishing. • NC-compatible design: Geometry similar to DIN 212. • 6.00mm nominal shank: The larger shank diameter provides the appropriate toolholding configuration for this size. • Uncoated design: Blank HSS-E cutting surface for precision reaming applications. Why choose Maykestag? Maykestag develops precision cutting tools for professional machining applications, combining controlled cutting geometry with carefully specified tool materials and dimensions. These factors are important for achieving reliable hole accuracy, surface finish and tool performance. The Code 3080 series combines HSS-E construction with H7 precision reaming geometry, a left-hand spiral and six cutting edges for accurate machine-based hole finishing across a broad range of engineering materials.
