Hss Mach Reamer Z6 5.1 H7 L/h Spiral

Product information

Maykestag HSS-E NC machine reamer 5.10mm H7 left-hand spiral Precision 5.10mm H7 NC machine reamer manufactured from HSS-E, featuring a left-hand spiral, six cutting edges and a straight 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, six cutting edges and a 5.00mm nominal shank diameter for standardised toolholding. With a 5.10mm reaming diameter and H7 tolerance, the reamer is designed to produce accurate and consistent finished holes in professional machining applications. Its NC-compatible design is similar to DIN 212, with a straight shank diameter particularly suited to standardised toolholding systems. 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. • 5.10mm 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. • 5.00mm shank: Straight shank diameter designed for standardised high-precision toolholding. • Uncoated design: Blank HSS-E cutting surface for general-purpose 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.
