Klein Tools 1000V Insulated Tool Sets for Utility and Electrical Work

When the job involves electrical utility work, heavy infrastructure, or energized environments, your tools need to do more than fit the fastener. They need to give you confidence, control, and protection when there is no room for error. Klein Tools is expanding its insulated tool lineup with three new professional sets designed for live line work up to 1000V.

Each set is built with ASTM F1505 certified three-part insulation, giving linemen and utility professionals the protection needed for demanding electrical applications. A visible white wear indication layer helps users quickly identify when a tool should be replaced, adding another level of jobsite safety. With oversized handles designed for torque, grip, and better control while wearing Class 2 gloves, these new Klein insulated tools are built for real field conditions.

Insulated Box End Wrench Set, 8-Piece
(KLN-47140INS)

This set is made for tightening and loosening bolts and nuts in utility and electrical infrastructure applications. This set includes commonly used wrench sizes, giving professionals the essentials they need for everyday live-line work.

Each wrench features three-part insulation rated for work up to 1000V and certified to ASTM F1505 standards. The white wear indication layer makes it easier to spot damage or wear in the insulation, helping users know when a wrench should be taken out of service. That detail matters on jobs where safety and reliability are critical.

The oversized handle design gives users more grip and control, especially when working with Class 2 gloves. This makes the set easier to handle in demanding environments where standard tools may feel too small or difficult to control. The stepped box end design also helps improve access in tighter spaces, making it easier to reach fasteners in challenging areas.

The KLN-47140INS set includes 3/8 inch, 7/16 inch, 1/2 inch, 9/16 inch, 5/8 inch, 11/16 inch, 3/4 inch, and 13/16 inch insulated box end wrenches. It also comes packed in a foam-lined, heavy-duty carrying case to keep the tools protected, organized, and ready for the next job.

Insulated T-Handle and Hex Bit Set, 9-Piece
(KLN-47120INS)

The Klein Tools Insulated T-Handle and Hex Bit Set is a 9-piece set designed for driving and fastening applications. Built for utility professionals, electricians, and linemen, this set combines insulated protection with the reach and control needed for hard-to-access fasteners.

Like the other new insulated sets, the KLN-47120INS features ASTM F1505 certified three-part insulation rated up to 1000V. The built-in white wear indication layer helps provide a clear visual alert when the insulation is worn and the tool may need replacement.

The oversized T-handle is designed for heavy infrastructure tasks, giving users added torque and a secure grip even while wearing Class 2 gloves. This is especially helpful when working in energized environments where control and comfort both matter. The set is also compatible with 3/8 inch drive tools, making it easy to integrate into standard tool setups.

For added reach, the kit includes both 3 inch and 6 inch extension bars. These extensions help users access fasteners in deeper or tighter spaces without needing to switch to a different setup. The included hex bit sizes are 5/16 inch, 3/8 inch, 7/16 inch, 1/2 inch, 9/16 inch, and 5/8 inch.

Insulated Ratchet and Socket Set, 12-Piece
(KLN-47110INS)

The Klein Tools Insulated Ratchet and Socket Set is a 12-piece set built for insulated driving and fastening work. Designed around a 3/8-inch drive system, this set gives professionals the ratchet, sockets, and extensions needed for a wide range of utility and electrical applications.

The KLN-47110INS set is rated for 1000V and ASTM F1505 certified, making it a strong choice for professionals working around energized equipment. Its three-part insulation includes a white wear indication layer, helping users easily identify when the insulation has been compromised or is ready for replacement.

The included insulated ratchet features an oversized handle that is optimized for better grip and torque while wearing Class 2 gloves. This makes it easier to stay in control during heavy-duty fastening tasks. The fixed ratchet head and quick release design help make socket changes more efficient, while the included 3 inch and 6-inch extension bars provide extra reach when working around obstructions or recessed fasteners.

This set includes 3/8 inch, 7/16 inch, 1/2 inch, 9/16 inch, 5/8 inch, 11/16 inch, 3/4 inch, 7/8 inch, and 1 inch standard-depth sockets.
