Shell Reamers are the hole making tools used to enlarge previously formed holes to a precise diameter with a smoother finish. Most shell reamers are made of high speed steel, used with special arbors which are tapered to fit the holes in the reamer. Straight fluted shell reamers are best for through holes, left-hand spiral flute models are better for blind hole machining. Shell reamers are recommended to machine holes with diameter larger than 20 mm or 3/4″. Cutting oils or coolant fluids are recommended for most reaming operations.
