KATO Round Electric Driver

KATO Round Electric Tool

Reliable. Accurate. Auto Reversible.

The KATO Round Electric (KRE) 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 KRE tool utilizes the KATO SB-400C (CT5405) and/or the SB-650C (CT5406) electric driver, depending on the thread size.

The SB-400C (CT5405) is capable of installing inserts up to 8-32 & M4, while the SB-650C (CT5406) is ideal for sizes from 8-32 & M4 up to 3/8" & M12. When either electric driver is used with the round shaft Mandrel Assembly operators can quickly and easily install Tangless CoilThread or CoilThread (Tanged) inserts. In Addition, the KRE tool is auto-reversing; once the insert is installed, the driver will automatically reverse minimizing overall installation time, while allowing operators to precisely adjust the auto-reversing torque to ensure consistent installation and prolong the life of the Mandrel Assembly. To see the KATO Round Electric in action! Please visit our Video Workshop in Katopedia.

How to Order - Complete Tool Requires the Following Parts:

SBT-50 Power Transformer

Transformer

(CT5407)

The SBT-50 Transformer converts standard 110V AC to DC for use with KATO’s CT5405, CT5406, & CT5408 Electric Drivers. Also available in a European model (CT5407-EU), which converts 240V AC to DC.

SB-400C/SB-650C Electric Driver

Electric Driver

(CT5405 & CT5406)

TThe SB-400C (CT5405) and SB-650C (CT5406) Electric Drivers include an auto-reversing feature that decreases overall installation time, resulting in increased productivity. For information on specific sizes, see Part Numbers.

Round Shaft Mandrel Assembly

Front Assembly

(See Part No.)

The KRE Mandrel Assembly is designed to install up to 3 Dia 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.

Tangless Handle

Adapter

2KREH-UI

The Tangless 2KRE Series Mandrel Assembly with OPTIONAL handle (2KREH-UI) can be used for manual installation.

Features & Benefits

  • Available for both Tangless and tanged CoilThread inserts.
  • Auto-Reversing for reduced installation time.
  • Utilizes KATO's new One Pawl Fits All system. (Tangless only)
  • Lower cost than similar drivers from competitors.

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. Use CT5407-EU for European model (240V).
  5. For manual installation only. Comes with 2KREH-UI handle.
