KFS-20 Brushless Electric Driver

KFS-20 Brushless Electric Driver

Designed for Speed and Efficiency

The KFS-20 Brushless Driver is designed for medium to high volume users of KATO Tangless and tanged CoilThread inserts. The KFS-20’s brushless motor requires less maintenance - no carbon brushes to purchase or replace.

The KFS-20 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. In addition, the KFS-20 is auto-reversing; once the insert is installed the driver will automatically reverse minimizing overall installation time. The KFS-20 utilizes two interchangeable compression springs to allow operators to precisely adjust the torque to ensure consistent installation and prolong the life of the installation tool.

The KFS-20 brushless driver has two installation options: the KATO Prewinder Electric (KPE) installation tool and the KATO Hex Electric (KHE) installation tool.

To see the KFS-20 in action! Please visit our Video Workshop in KATOpedia.

Please Note:

  1. The Prewinder Electric tool (KPE) is designed to work with 1, 1.5, and 2 diameter inserts, for 2.5 and 3 diameter inserts please contact KATO for availability. KATO strongly recommends using the Prewinder Electric Tool for Fine and Metric thread size.
  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.
  3. Use CT5420-EU for European Model (240V) only.
