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.
