Please view all photos. Selecting a Chucking Reamer Chucking reamers are rotary cutting tools used to shape, enlarge, and finish pre-cut holes to a tight tolerance. They are general purpose reamers for a variety of applications and materials and fit in the chuck of machines such as drill presses, turret lathes, and screw machines. Chucking reamers resemble drill bits, except the cutting edge is on the outside rather than the tip and they are used to make the final cut on holes with high precision.Chucking reamers have either a helical or straight set of parallel cutting edges or flutes along the length of the body. Left hand spiral flutes eject chips and coolant forward and away from the tool operator while right hand flutes pull chips and coolant from the hole. Straight chucking reamers collect chips within the flute section.Chucking reamers are usually made of high speed steel (HSS), cobalt, or tungsten carbide (WC) for hardness and resistance to high temperatures. The flutes are beveled at an angle of 40-50 degrees to maintain sharpness over time. Chucking reamers come in a variety of shank styles including straight, Morse taper, and stub screw machine.
