Maykestag HSS-E NC machine reamer 5.20mm H7 left-hand spiral
Precision 5.20mm H7 NC machine reamer manufactured from HSS-E, featuring
a left-hand spiral, six cutting edges and a straight shank for
standardised high-precision toolholding.
The Maykestag Code 3080 is an HSS-E NC machine reamer designed for
precision finishing of existing holes. The tool features a left-hand
spiral, six cutting edges and a 5.00mm nominal shank diameter for
standardised toolholding. With a 5.20mm reaming diameter and H7
tolerance, it is designed to produce accurate and consistent finished
holes in professional machining applications. Its NC-compatible
design is similar to DIN 212, with a straight shank diameter suitable
for standardised toolholding, particularly in hydro-expansion and
high-precision chucks.
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.
