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.
