The Rotozip Tool Corp was a company started by Bob Kopras, an American drywall installer who pioneered this type of saw. Rotozip was later acquired by Bosch Tool Corp. in 2003. [1] This type of tool was originally developed for making cut-outs in drywall but it was later discovered that myriad other materials could easily be cut using the tool. [2]
A tool similar to a router, but designed to hold smaller cutting bits—thereby making it easier to handle for small jobs—is a laminate trimmer. A related tool, called a spindle moulder (UK) or shaper (North America), is used to hold larger cutter heads and can be used for deeper or larger-diameter cuts.
Burrs are a rotary analog to files that cut linearly (hence their alternate name, rotary files). They share many similarities with endmills and router bits, with the notable distinction that the latter typically have their toolpaths dictated by the machine, while burrs are frequently operated in a freehand manner.
In machining, a tool bit is a non-rotary cutting tool used in metal lathes, shapers, and planers. Such cutters are also often referred to by the set-phrase name of single-point cutting tool , as distinguished from other cutting tools such as a saw or water jet cutter .
