A reamer is a type of rotary cutting tool used in metalworking. Precision reamers are designed to enlarge the size of a previously formed hole by a small amount but with a high degree of accuracy to leave smooth sides. There are also non-precision reamers which are used for more basic enlargement of holes or for removing burrs.
A chamber reamer is a specific type of fluted reamer used by gunsmiths and firearms manufacturers to cut the chamber of a handgun, rifle, or shotgun. The chamber reamer is inserted into the bore of a barrel and held stationary while the barrel is turned around it (typically by means of a lathe ).
A citrus reamer, also known as a lemon reamer or simply a reamer, is a small kitchen utensil used to extract the juice from a lemon or other small citrus fruit. [1] [2] [3] The reamer extracts juice using a convexly tapered conical mandrel, with troughs or ridges running the length of the mandrel. The mandrel is mounted either within a dish to ...
Roller reamer. Roller reamers are employed in boring operations for the oil & gas industry. The main function of roller reamers cut earth formations to enlarge the borehole to the desirable size during well drilling operation, which may be the original size of the drill bit in the case where the drill bit wears to be under-gauged. However, even ...
Reamers are stabilisers that have cutting elements embedded on their fins, and are used to maintain a gauged well-bore. They can be used to drill out doglegs and key-seats in hard formations. Due to the cutting ability of the reamer the bit does less work in maintaining well-bore gauge and more work drilling.
Rotary cutting tools include drill bits, countersinks and counterbores, taps and dies, reamers, and cold saw blades. Other cutting tools, such as bandsaw blades, hacksaw blades, and fly cutters, combine aspects of linear and rotary motion. The majority of these types of cutting tools are often made from HSS (High-Speed-Steel).
Taper pin reamers are designed to prepare the hole for taper pins. Metric taper reamers are designated by the small diameter. Metric taper reamers are designated by the small diameter. For example, a 2 mm taper pin reamer has a 1.9 mm small end (2 mm nominal size) and a 2.86 mm large end.
Large numbers have been sold, despite frequent criticisms that the kitchen tools do not work very well. [5] For the tenth anniversary of its launch, 10,000 Juicy Salifs were issued, individually numbered and gold-plated. [6] The gold-plated version has been described as an "ornament" because citric acid would discolor and erode the gold plating.
