IMPA 630740 HAND REAMER 20mm HSS helical flute DIN 206-B

The IMPA 630740 HAND REAMER 20mm HSS helical flute DIN 206-B is a high-speed steel hand reamer with a helical flute. It is designed for use on ferrous and non-ferrous metals, and is especially well-suited for reaming holes in stainless steel. The flute is helical, which gives it a cutting action that is more efficient than a straight flute, and the HSS construction means that it will retain its sharpness for a longer period of time. The reamer is also designed with a chisel point, which allows it to start the reaming process more easily.
