Carbide Spiral Reamer, High-Precision Tolerance Model

Brand :
MISUMI
Caution
Product Description
[Features]
·Achieves high-precision hole finishing by narrowing the cutting diameter tolerance width
·High-speed cutting greatly improves efficiency compared to high-speed steel reamers
·The long lifespan allows high-precision machining to be maintained for a long time.
·Even higher speed cutting is possible by adopting helical flutes

More Information

●High-accuracy hole finishing is achieved by narrowing the width of the blade diameter tolerance.
●High-speed cutting provides a significant improvement in efficiency compared to a high-speed steel reamer.
●Thanks to its long lifetime, high-precision machining can be sustained over a long period.
●High-speed cutting can be done even faster with the adoption of a helical flute.
