Klein Tools Cable Cutter 63050-INS 1000V Insulated (4/0 Aluminum 2/0 Soft Copper Capacity One Handed Shear ASTM F1505 Electrician Hand Tool)

Klein Tools 63050-INS 1000V Insulated One-Handed Cable Cutter

The Klein Tools 63050-INS 1000V Insulated Cable Cutter functions as a high-leverage dielectric manual shear engineered to cut copper, aluminum, and communication cables near energized components. Certified to ASTM F1505 and IEC 60900 standards for live-line shock protection up to 1000V AC, this 1.0-pound USA-made tool features induction-hardened forged steel shear jaws that cut up to 4/0 aluminum, 2/0 soft copper, and 100-pair 24 AWG communication cables. Outfitted with a dual-layer flame-retardant orange and white insulation system, integrated safety hand guards, and a hot-riveted joint, this cutter enables commercial electricians and utility linemen to perform one-handed cable sizing inside crowded breaker panels and switchgear enclosures.

Best Used For:

• Energized Breaker Panel Cable Shearing: Cutting up to 2/0 soft copper and 4/0 aluminum conductors inside live 1000V rated commercial distribution boards.
• High-Density Communication Cable Trimming: Slicing 100-pair 24 AWG communication cables square for telecommunications terminal installations.
• Confined Space Service Entrance Work: Executing clean, one-handed cable cuts inside narrow junction boxes, meter bases, and motor control centers.

Key Performance & Safety Features

• 1000V Dielectric Safety Certification: Individually batch-tested to satisfy ASTM F1505 and IEC 60900 standards for live-line shock protection up to 1000V.
• High-Capacity Shear-Type Jaws: Precision-ground induction-hardened steel blades shear clean, rounded ends through 4/0 aluminum and 2/0 soft copper without strand deforming.
• One-Handed High-Leverage Operation: Compact mechanical design allows technicians to cut large-diameter cables in cramped terminal housings using one hand.
• Dual-Layer Bonded Insulation System: Flame-retardant bright orange outer coating overlies a white dielectric inner substrate that alerts operators if insulation becomes damaged.
• Integrated Handle Safety Guards: Ergonomic handle tab barriers prevent gloves from sliding forward toward underlying conductive steel joints.
• Hot-Riveted Hinge Joint: Precision rivet alignment delivers smooth closing action without blade wobble or jaw misalignment over repeated cycles.

Technical Specifications

Pro-Tip: Before making one-handed cuts on 2/0 soft copper or 4/0 aluminum cable with the Klein 63050-INS, seat the cable as deep into the curved shear jaws as possible. Cutting near the pivot point maximizes mechanical advantage and prevents the cable from walking out of the jaws.
