KATO Prewinder Electric Driver

KATO Prewinder Electric Tool

Still The Fastest, Only Better...

KATO New KFS-20 Brushless Electric Driver

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

The KFS-20 brushless electric driver requires 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. KATO engineers designed the KFS-20 with an even lower minimum torque setting than the KFS-12. In fact, the torque adjustment on the KFS-20 is more sensitive than any previous electric driver.

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

The Best of Both Worlds... Exclusive to KATO, the Prewinder Electric tool combines the best features of the air and electric installation tools.The KATO Prewinder Electric tool is the fastest semi-automatic installation system available for helically coiled screw thread inserts (CoilThread, Helicoil, Recoil, etc.)!

The KATO Prewinder Electric (KPE) installation tool is designed for medium to high volume users of KATO Tangless and tanged strip-feed packaged CoilThread inserts (can be used with bulk inserts). The KPE tool is the industry's first and only electric installation tool that utilizes a prewinder, which compresses the insert, allowing for much easier and consistent installation. The KPE tool is comprised of the KATO KFS-20 Electric Driver (CT5420), the innovative KATO Prewinder Adapter (CT5420-PA), and a Front End Assembly.

In addition, the KPE tool is auto-reversing; once the insert is installed the driver will automatically reverse minimizing overall installation time. The KFS-20 electric driver (CT5420) utilizes a powerful electric motor and two torque adjusting compression springs (one for smaller thread sizes and one for larger thread sizes) to install inserts up to 1/4" and M6 in diameter. The adjustable installation torque (through a window in the prewinder adapter) ensures consistent installation and prolongs the life of the mandrel assembly.
