Maykestag HSS-E NC machine reamer 3.80mm H7 left-hand spiral

Product information

Maykestag HSS-E NC machine reamer 3.80mm H7 left-hand spiral Precision 3.80mm H7 NC machine reamer manufactured from HSS-E, featuring a left-hand spiral, six cutting edges and geometry similar to DIN 212 for accurate finishing of pre-drilled holes. The Maykestag Code 3080 is an NC machine reamer manufactured from HSS-E and designed for precision finishing of drilled holes. Its left-hand spiral geometry and six cutting edges provide a controlled cutting action while supporting effective chip evacuation during the reaming process. With a 3.80mm H7 reaming diameter, 4.00mm nominal shank and 57mm overall length, this reamer is suited to precision machining applications where accurate hole sizing and a high-quality finished surface are required. The tool features geometry similar to DIN 212 and is designed for machine-based reaming operations. 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: Cobalt-alloyed high-speed steel provides enhanced heat resistance and wear resistance for demanding precision reaming applications. • 3.80mm reaming diameter: Precision cutting diameter for finishing small-diameter holes. • ISO H7 tolerance: Manufactured for precision finishing of holes to the specified H7 tolerance. • Left-hand spiral: Left-hand helical cutting geometry provides controlled chip movement during the reaming operation. • Six cutting edges: Six-flute geometry provides a balanced cutting action and supports consistent hole finishing. • NC machine reamer: Designed for machine-based precision reaming applications. • DIN 212 geometry: Manufactured with geometry similar to DIN 212. • 4.00mm nominal shank: Provides a robust shank configuration for suitable high-precision toolholding systems. Why choose Maykestag? Maykestag is an Austrian cutting-tool manufacturer focused on precision-manufactured tools for professional machining. Consistent control of cutting geometry, tool material and dimensional tolerances is important for achieving reliable machining results, tool life and finished-hole quality. The Code 3080 series combines HSS-E tool material with precision H7 reaming geometry and a left-hand spiral configuration, providing a practical solution for accurate hole finishing in professional machining environments.
