Maykestag HSS-E NC machine reamer 4.80mm H7 left-hand spiral
Precision 4.80mm 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
4.80mm reaming diameter, 5.00mm nominal shank and catalogue-specified
dimensions, 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.
