HAND EXPANSION REAMERS

Hand Expansion Reamers are adjustable, multi-fluted end cutting tools used to slightly enlarge previously formed holes to a precise diameter with a smoother finish. The adjusting screw can be tightened to permit expansion back to the initial size after wear in the cutting end, increasing tool life and saving money. It can then be reground to the appropriate size and sharpened. Straight flutes provide a smooth finish and are more accurate than adjustable blade expansion reamers, while spiral flute models provide better chip clearance and are recommended for blind hole applications. Square shank fits in a T-handle or straight tap wrench to provide a useful repair tool in the field.
