KATO Prewinder Air (KPA)

KATO Prewinder Air Tool

The Widest Range of Sizes

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 Heli-Coil and Recoil brand inserts, and some components may be interchangeable with Heli-Coil and Recoil brand tools. For more information contact Tech-Group. To see the KATO Prewinder Air in action! Please visit our Video Workshop in Katopedia.

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. For information on specific sizes, see Part Numbers.

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.

Features & Benefits

  • Ideal for use with strip feed inserts (for sizes 1/4", M6 and smaller).
  • Prewinder threads help facilitate installation. This is especially helpful when installing UNF or Metric thread sizes.
  • Installs a broad range of sizes for both Tangless and tanged inserts (2-56 thru 1/2" & M2.5 to M12).
  • Semi-Automatic Installation for decreases installation time
  • Compatiable with screw thread inserts from Heli-Coil, Recoil and others.
  • Utilizes KATO's One Pawl Fits All system (Tangless only).
