• 1.Adjustment feature allows reamer to maintain a specific size by compensating for wear.
• 2.Reamer with one or more teeth to cut holes machined surface of the thin metal layer rotary cutter. After working through the hole cutter can obtain precise size and shape.
• 3.Scope of application: reamers to ream the workpiece has been drilling (or bore) hole behind the processing, primarily in order to improve the machining precision of the hole, reducing the roughness of the surface, is finishing and semi-finishing for hole machining tool
• 4.Blades are adjustable and move within tapered slots in the reamer body.Only could use by hand, use on machine could damage the blade.
• 5.To adjust these reamers the blades are moved within these slots by loosening the nut at one end and tightening the nut at the other.Movement permits the reamer to be set to any desired diameter within the range of the size adjustment.
