• The Disposable blade slide along a tapered groove.
• The act of tightening and loosening the restraining nuts at each end varies the size that may be cut.
• The absence of any spiral in the flutes restricts them light usage as they tend to chatter.
• They are also restricted to usage unbroken holes. If a hole has an axial split along it, such as a split bush or a clamping hole each straight tooth will in turn drop into the gap causing the other teeth to retract from their cutting position.
• Adjustable hand reamers are designed with enough adjustment to ream almost any odd size hole.
• The blades are made of high carbon steel for long life and can be adjusted by loosening one nut while tightening the other.
• They are used mostly for repair work in the field.
