Specification Brand : HARFINGTON BulletPoint1 : Size - 1:50 taper reamer; cutting diameter: 5mm / 0.2" (small), 6.2mm / 0.24" (big); accuracy: H8; tool flute length: 60mm / 2.36"; square shank diameter: 4mm / 0.16"; overall length: 85mm / 3.35"; flutes quantity:6. BulletPoint2 : Material - High-speed steel tools are suitable for most general applications, offering a combination of hardness and toughness for wear resistance and increased work efficiency. BulletPoint3 : Feature - Reaming holes can be of precise size and shape; the reamers are precision ground with straight edges to provide a finishing finish while providing long tool life. BulletPoint4 : Application - Hand reamers can be hand operated using wrenches for light cutting, repair work, removing stock, or simply for enlarging holes. BulletPoint5 : Note - Frictional heat will be caused during the hole expansion friction process. Using appropriate lubricants can reduce friction, increase the cutting speed of the reamer, and extend the tool's life.
