KFS-25 Brushless Electric Driver

Our Most Powerful Driver

The KFS-25 Brushless Driver is designed for low to medium volume users of KATO Tangless and tanged bulk packaged CoilThread inserts. The KFS-25’s brushless motor requires less maintenance - no carbon brushes to purchase or replace.

The KFS-25 is powerful enough to install inserts up to 1/2” and M12, yet sensitive enough to install inserts as small as 6-32 and M4. In addition, the KFS-25 is auto-reversing; once the insert is installed the driver will automatically reverse minimizing overall installation time. The KFS-25 allows operators to precisely adjust the torque to ensure consistent installation and prolong the life of the installation tool.

The KFS-25 is designed to be used with the KATO Hex Electric Tool and incorporates a 1/4” quick-disconnect keyless chuck system. Operators can quickly and easily change from one thread size to another, or between Tangless and tanged CoilThread inserts.

Please Note:

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.
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.
Not compatible with the KATO One Pawl Fits All system at this time.
Use CT5425-EU for European Model (240V) only.
