46mm Machine Chucking Reamer Morse Taper Shank HSS H7 GOST 1672

• Use straight flute reamers in through hole applications only.
• High speed steel offers good wear resistance in mild steels and non-ferrous materials.

A machine reamer only has a very slight lead in. Because the reamer and work piece are pre-aligned by the machine there is no risk of it wandering off course. In addition the constant cutting force that can be applied by the machine ensures that it starts cutting immediately. Spiral flutes have the advantage of clearing the swarf automatically but are also available with straight flutes as the amount of swarf generated during a reaming operation should be very small.
