Maykestag HSS-E NC machine reamer 4.60mm H7 left-hand spiral

Maykestag HSS-E NC machine reamer 4.60mm H7 left-hand spiral

Precision 4.60mm H7 NC machine reamer manufactured from HSS-E, featuring a left-hand spiral and six cutting edges for accurate finishing of pre-drilled holes.

The Maykestag Code 3080 is an NC machine reamer manufactured from HSS-E for precision finishing of existing holes. Its left-hand spiral and six cutting edges provide controlled cutting action for reliable hole finishing. With a 4.60mm reaming diameter and catalogue-specified shank and overall dimensions, this reamer is suited to precision machining applications where accurate hole sizing and a high-quality finished surface are required. The tool has 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.
• 4.60mm reaming diameter: Precision cutting diameter for finishing small-diameter holes.
• ISO H7 tolerance: Designed for precision finishing to the specified H7 hole tolerance.
• Left-hand spiral: The left-hand spiral geometry provides controlled chip movement during reaming.
• Six cutting edges: Six-flute geometry supports balanced cutting and consistent hole finishing.
• NC machine reamer: Designed for machine-based precision reaming applications.
• DIN 212 geometry: Geometry similar to DIN 212.
• Catalogue-matched dimensions: Shank and tool dimensions follow the Maykestag catalogue specification for this size.
