Maykestag HSS-E NC machine reamer 2.40mm H7 left-hand spiral

Maykestag HSS-E NC machine reamer 2.40mm H7 left-hand spiral

Precision 2.40mm H7 NC machine reamer manufactured from HSS-E, featuring a left-hand spiral, four 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 four cutting edges provide a controlled cutting action while supporting effective chip evacuation during the reaming process. With a 2.40mm H7 reaming diameter, 3.00mm 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 a straight nominal shank designed for standardised high-precision 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: Cobalt-alloyed high-speed steel provides enhanced heat resistance and wear resistance for demanding precision reaming applications.
• 2.40mm reaming diameter: Precision cutting diameter for finishing small-diameter holes.
• ISO H7 tolerance: Manufactured to provide the H7 dimensional tolerance specified for the finished hole.
• Left-hand spiral: Left-hand helical cutting geometry provides controlled chip movement during the reaming operation.
• Four cutting edges: Four-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.
• 3.00mm nominal shank: Provides a robust shank configuration for suitable high-precision toolholding systems.
• 57mm overall length: Provides a compact configuration suited to precision machine reaming.
