Description

15pcs Adjustable Hand Reamer Set HV to H11 (1/4 inch to 1/1.16 inch)
Description: An adjustable hand reamer can cover a small range of sizes. They are generally referenced by a latter which equates to a size range. 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 have a tendency 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.
