Douglas Harper's Etymology Dictionary
"rough sound of the letter -r-" (especially that common in Northumberland), 1760, later extended to "northern accented speech" in general. Possibly the sound of the word is imitative of the speech peculiarity itself, or it was adapted from one of the senses of bur (q.v.), perhaps from the phrase to have a bur in (one's) throat (late 14c.), which was a figure of speech for "feel a choking sensation, huskiness." OED says the Scottish -r- is a lingual trill, not a true burr.
Etymology 1 n. 1 A sharp, pointy object, such as a sliver or splinter. 2 A bur; a seed pod with sharp features that stick in fur or clothing. 3 A small piece of material left on an edge after a cutting operation. 4 A thin flat piece of metal, formed from a sheet by punching; a small washer put on the end of a rivet before it is swaged down. 5 A broad iron ring on a tilting lance just below the grip, to prevent the hand from slipping. 6 The earlobe. 7 The knot at the bottom of an antler.

Burr may refer to:
Burr (1973), by Gore Vidal, is a historical novel that challenges the traditional founding-fathers iconography of United States history, by means of a narrative that includes a fictional memoir, by Aaron Burr, in representing the people, politics, and events of the U.S. in the early nineteenth century.
In the careers of his life, Aaron Burr was the third Vice President of the United States (1801–05), an officer in the Continental Army, during the American War of Independence (1775–83), a lawyer (1782), and a United States Senator from the State of New York (1791–97). In consequence to political and personal enmity, while he was Vice President, Burr killed Alexander Hamilton in a duel on 11 July 1804. After public life, he was embroiled in the Burr Plot (1807), and was acquitted of treason against the United States; then, in Europe, he failed to obtain Napoleonic military aid to conquer Spanish Florida. In 1812, Burr returned to the United States, and practiced law in New York City, until his death in 1836.
Burr is the first book of the seven-novel series, Narratives of Empire, with which Gore Vidal examined, explored, and explained the imperial history of the United States; chronologically, the six other historical novels of the series are Lincoln (1984), 1876 (1976), Empire (1987), Hollywood (1990), Washington, D.C. (1967), and The Golden Age (2000).
Burrs (sometimes called rotary files) are small cutting tools used in die grinders, rotary tools, or dental drills. The name may be considered appropriate when their small-sized head (3 mm diameter shaft) is compared to a bur (fruit seed with hooks) or their teeth are compared to a metal burr.
Burrs are a rotary analog to files that cut linearly (hence their alternate name, rotary files). They are also in many ways comparable to endmills and to router bits; a distinction is that the latter usually have their toolpath controlled by the machine, whereas burrs are often used freehand. However, there is substantial overlap in the use and toolpath control of these various classes of cutters, and in the outcomes accomplished with them. For example, endmills can be used in routers, and burrs can be used like endmills in milling by CNC or manual machine tools. In fact, burrs (the tools) are often used in CNC machining centers for removing burrs (the small flakes of metal) after a machining process.
To maintain the correct surface speed and cutting conditions, burrs are rotated at high speed (thousands or tens of thousands of RPM; often the top speed available on a given spindle). The cutters shown in the image are made from tungsten carbide, which allows them to run at higher speeds than similar HSS cutters, yet still maintain their cutting edges.
Because the cutting edges are so small, they can often be touched when spinning by a finger without cutting the skin, which flexes out of the way, although it would not be safe to pinch or grip them from two sides. Hard metal or ceramic workpieces cannot flex beyond the cutting edges, so the tools remove material from them. This characteristic makes them suitable for dentistry, as the tool will grind the hard enamel of teeth, yet leaves soft mouth tissues unharmed if the tool should erroneously touch them.

A burr is a raised edge or small piece of material remaining attached to a workpiece after a modification process.
It is usually an unwanted piece of material and is removed with a deburring tool in a process called 'deburring'. Burrs are most commonly created by machining operations, such as grinding, drilling, milling, engraving or turning. It may be present in the form of a fine wire on the edge of a freshly sharpened tool or as a raised portion of a surface; this type of burr is commonly formed when a hammer strikes a surface. Deburring accounts for a significant portion of manufacturing costs.
In the printmaking technique of drypoint, burr, which gives a rich fuzzy quality to the engraved line, is highly desirable—the great problem with the drypoint medium is that the burr rapidly diminishes after as few as ten impressions are printed.
