A rotary reciprocating saw is a type of saw that spins a cutting implement around a rotary axis, instead of thrusting it along a linear axis. The first use of such devices was in medicine , where cutting through bone warranted the need for a saw with minimal stroke length, and a cutting action that could be implemented through depth cut rather ...
Early cordless models were marketed as the Dremel Freewheeler. Dremel options include a miniature planer attachment, and a jigsaw attachment that lets the tool act much like a small reciprocating saw.

A rotary hammer, also called rotary hammer drill [1] is a power tool that can perform heavy-duty tasks such as drilling and chiseling hard materials.

SKIL can trace its heritage to the invention of the circular saw by Edmond Michel in 1924, which led to the development of the SKILSAW circular saw Model 77 in 1937. Now referred to as “the saw that built America,” the Model 77 set the industry standard for handheld worm-drive circular saws which remains in production almost unchanged today ...
Bow drill (strap-drill) are the first machine drills, as they convert a back and forth motion to a rotary motion, and they can be traced back to around 10,000 years ago. It was discovered that tying a cord around a stick, and then attaching the ends of the string to the ends of a stick (a bow), allowed a user to drill quicker and more efficiently.
Pneumatic drills were developed in response to the needs of the mining, quarrying, excavating, and tunneling. A pneumatic drill was proposed by C. Brunton in 1844. [4] [5] In 1846, a percussion drill that could be worked by steam, or atmospheric pressure obtained from a vacuum, was patented in Britain by Thomas Clarke, Mark Freeman, and John ...
