The KATO Prewinder Air (KPA) installation tool is designed for medium to high volume users of KATO Tangless and tanged strip-feed package CoilThread inserts (can also be used with bulk inserts). The KATO Prewinder Air tool is comprised of the KATO Air Motor (CT25017), KATO Adapter (CT9605 or CT9705), and a Front End Assembly. When used together, the KPA tool is capable of installing KATO CoilThread inserts up to 1/2” and M12 coarse and fine thread sizes Another important component to the air tool system is the KATO Filter-Regulator-Lubricator (2KFRL-1). The Filter-Regulator-Lubricator cleans the air, allows precise control of the air pressure, and lubricates the air motor. In addition, the KPA tool features semi-automatic installation; press the lever to install the insert, release the lever and the air motor reverses. For installation of Tangless CoilThread Inserts sizes: 2-56, 4-40, M2.5, and M3, the KATO torque limiting Clutch Drive (CT9602) is required to control the installation torque generated by the air motor, and prevent damage to the Front-End Assembly. The KATO Prewinder Air tool will also work with Helicoil and Recoil brand inserts, and some components may be interchangeable with Helicoil and Recoil brand tools
