[https://en.wikipedia.org/wiki/Reamer '''Reamers'''] are used to enlarge previously drilled holes with a high degree of accuracy. They have a series of cutting blades along their length and can be either '''Hand Reamers''', operated with a '''[[Taps_and_Dies#Tap_Wrenches|Tap Wrench]]''', or '''Machine Reamers''' which are driven by a '''[[Centre Lathe]]''', '''[[Milling Machine]]''' or '''[[Drill Press]]'''.


'''Tapered Reamers''' can be used to shape holes drilled to receive '''[[Pins and Clips|Taper Pins]]''' or '''[[Pins and Clips|Cotter Pins]]''' and '''Morse Taper Reamers''' are used to finish holes bored to receive '''[[Twist Drills|Taper Shank]]''' drills for example.


'''Expanding Reamers''' are adjustable over a small range of sizes and are used to take light cuts to bring a hole accurately to size to fit an existing shaft or spindle for example.
