KATO Hex Electric Driver

KATO Hex Electric Tool

Designed for Speed and Efficiency

New KATO KFS-20 & KFS-25 Brushless Electric Drivers

KATO engineers began by taking all the great features of the KFS-12 electric driver and rolled them into the all new KFS-20 & KFS-25 brushless electric drivers. The KFS-20 & KFS-25 brushless electric drivers have a greater efficiency and is more durable than any previous electric driver offered for insert installation.

The KFS-20 & KFS-25 brushless electric drivers require less maintenance - no carbon brushes to purchase or replace. The KFS-20 brushless electric driver is powerful enough to install inserts up to 1/4” and M6, yet sensitive enough to install inserts as small as 2-56 and M2.5. While the KFS-25 electric driver was designed to install inserts from 6-32 to 1/2” and M4 to M12.

The KFS-20 & KFS-25 brushless electric drivers utilizes the smallest power supply of any previous tool. The power supply is up to 4x smaller and at 11.5 oz is 8x lighter than the SBT-50 (CT5407) power transformer. Best of all the power supply is included with the KFS-20 & KFS-25 brushless electric drivers. No separate part number to remember or purchase!

The KATO Hex Electric (KHE) installation tool is designed for medium to high volume users of KATO Tangless and Tanged bulk packaged CoilThread inserts (for Strip-Feed packaged inserts KATO recommends using the Prewinder Electric Tool). The KHE tool utilizes the KFS-20 (CT5420) & KFS-25 (CT5425) electric drivers, which incorporates a 1/4" Quick-Disconnect keyless chuck system. Operators can quickly and easily change the installation Mandrel Assembly from one thread size to another or between Tangless CoilThread and CoilThread (tanged) inserts.

In addition, the KHE tool is auto-reversing; once the insert is installed the driver will automatically reverse minimizing overall installation time. Both KFS-20 & KFS-25 electric drivers allow operators to precisely adjust the auto-reversing torque to ensure consistent installation and prolong the life of the Mandrel Assembly.

How to Order - Complete Tool Requires the Following Parts:

CT5420 with Power Supply

KFS-20 Electric Driver

CT5420 - Includes Power Supply

The KFS-20 Electric Driver (CT5420) was designed with strategically located external threads that make using the KATO Prewinder Adapter possible. When used with the Prewinder Adapter and the KPE Series front end assembly, the KATO Prewinder Electric Tool is the fastest installation system for helical coil screw thread inserts (CoilThread, Helicoil, Recoil, etc.)!

CT5425 with Power Supply

KFS-25 Electric Driver

CT5425 - Includes Power Supply

Need more power? The KFS-25 Electric Driver (CT5425) was designed to install inserts from 6-32 to 1/2” and M4 to M12. The driver features a 1/4” quick disconnect hex shaft, reducing setup time, and a Forward/Neutral/Reverse Switch.

Hex Shaft Mandrel Assembly

(See Part No.)

The KHE Mandrel Assembly is designed to install up to 3D nominal length CoilThread Inserts. The slim profile makes it possible to install CoilThread inserts in hard to reach places. For information on specific sizes, see Part Numbers.

Please Note:

  1. The Tangless Mandrel Assembly consists of the installation mandrel (hex shaft), installation pawl, spring, pin, wrenches, and adjusting sleeve fully assembled and ready for use.
  2. For Improved Tangless installation UNF & Metric thread sizes use a different installation mandrel for Free-Running and Locking CoilThread inserts, this is indicated by the -F and -L designation in the part number. KATO strongly recommends using the Prewinder Electric Tool (KPE) for Fine and Metric thread size.
  3. Not compatible with the KATO One Pawl Fits All system at this time.
  4. For these smaller thread sizes, KATO recommends manual installation only. These tools include a gage handle.
  5. Use CT5420-EU and CT5425-EU for European Model (240V) only.
