Reamer is a rotating cutting tool with a cylindrical or conical shape that is used to enlarge and finish holes that have already been drilled, bored, or cored to precise specifications. Reamer Cutting Tools No hole can be created with a reamer. All reamers have longitudinal flutes or grooves (eight are frequently employed), which can be straight or helical. Cutting can be done on the tool's sides using the sharpened edges of the apexes between the flutes, or it can be done at the reamer's tip using chamfered edges. The flutes allow lubricating and cooling liquid to reach the cutting blades while also allowing chips to pass through. Machine or chucking, reamers, and hand reamers are the two primary classes of reamers.

Drill presses, lathes, and screw machines are a few examples of machines that use machine reamers. They can have either straight or tapered shanks; hand reamers feature a straight shank with a square end to accommodate a wrench and a slightly tapered shank to assist reamer insertion. Expansion reamers are accessible when it's necessary to slightly increase reamed holes. These are longitudinally divided, and by moving the end screw, inside cones expand to change the diameter. High-speed steel cemented carbides, and high-carbon steel is used to make reamers.

The Uses of Reamer

Reamers are a particular kind of rotary cutting tool used primarily in metalworking.A reamer is a tool that is used to enlarge or complete pre-drilled holes, as well as holes that have been bored or cored, to ensure a precise diameter.The reamer is designed for turret lathes and drill presses.In the machine that cuts screws, reaming is also employed.
