Vintage Machinery entry for Koett Universal, Inc.

Description: |
| According to an article in the 1948-11-13 Oneonta Star, at that time Koett had 15 employees and was manufacturing about 100 grinders per month, which was to double by the end of the year. "...the Koett universal is a versatile machine tool. It can be mounted on a lathe, milling machine, planer, shaper, etc. It can also be used as a machine in itself. The machine performs internal or external grinding, milling, boring or drilling. What impressed us, however, was the speed of the unit. By turning a little knob on top of the machine, Mr. Koett had it traveling from 500 to 31,200 revolutions per minute. The speeds are made possible by pulley changes and a rheostat control. 'It's a grand all-purpose machine, and at high speed there is no vibration or friction,' said Mr. Koett. 'We know that the machine will do 187 jobs in the wood, iron and plastic industries, both in conjunction with other machines and itself.'" |
