Chucking reamers are also known as machine reamers.
They are the most common type of reamers used in lathes, drill presses and screw machines that provide a smooth finish to the hole.
Regarding the counts of flutes, the more flutes a chucking reamer is with, the better performance it has. Chucking reamers come with straight flutes and straight shanks.

MaterialH.S.S. M2 high speed steel. M2 grade high speed steel is the most widely used material in tool making for its superiorities; With higher wear resistance, anti-bending strength, toughness, and thermo-plasticity, M2 grade high speed steel makes chucking reamer set a better option for hole machining.
High wear resistance: the reamers will less likely wear off during machining process and have longer cycle; Therefore, the quality of the work remains constant.
Anti-bending strength and toughness: the reamers will only take minor impact from each use; Both outside shape and inside structure are not likely to change.
Toughness: high toughness significantly shrinks machining duration, making the work more efficient.
Thermo-plasticityalthough under a low cutting speed, the friction between the cutting tool and work piece generates heat; Non-thermo-plasticity materials may subject to permanent hardness decrease; But M2 H.S.S. can effectively resist this type of harm and continuously serve as new tools.
