Prewinder Air Tool

The Prewinder Air (KPA) installation tool is designed for medium to high volume users of Tangless® and tanged strip-feed package CoilThread® inserts (can also be used with bulk inserts). The Prewinder Air tool is comprised of the Air Motor (CT25017), Adapter (CT9605 or CT9705), and a Front End Assembly. When used together, the KPA tool is capable of installing CoilThread® inserts up to 1/2” and M12 coarse and fine thread sizes

Another important component to the air tool system is the 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 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. 

Prewinder Air Tool Components

Air Motor

Air Motor (CT25017)

(CT25017)

The powerful KPA Motor is designed to install Tangless or tanged CoilThead® inserts for sizes up to 1/2" and M12 coarse and fine thread sizes.

Adapters

KPA Adapter (CT9605 and CT9705)

(CT9605 or CT9705)

The KPA Adapter acts as a bridge between the air motor and the front-end assembly.

Front-End Assembly

Front-End Assembly

(See Part No.)

The Front-End Assembly is available for a variety of thread sizes and is designed to install 1, 1.5 and 2 diameter nominal length inserts. 

Filter-Regulator-Lubricator

Filter-Regulator-Lubricator (2KRL-1)

(2KFRL-1)

The Filter-Regulator-Lubricator is critical to the longevity of the pneumatic system. Each front-end assembly is stamped with a maximum air pressure, the filter-regulator-lubricator ensures the air pressure never exceeds that value. A Filter-Regulator Lubricator is required for each air motor in operation.

Torque Limiting Clutch Drive

Torque Liminting Clutch Drive (CT9602)

(CT9602)

The KATO® Torque Limiting Clutch-Drive was designed with one goal in mind: to prolong the life of your air tool mandrels and prevent breakage under excessive torque. Note: The Clutch Drive is required for Tangless 2-56, 4-40, M2.5 and M3 thread sizes.
