Klein Tools 63750 12-1/8 Inch Heavy-Duty Ratcheting Cable Cutter

The Klein Tools 63750 12-1/8-Inch Ratcheting Cable Cutter functions as a high-leverage mechanical shearing hand tool engineered to cut large-diameter soft copper, aluminum, and multi-pair communication cables. Forged from induction-hardened tool steel, this 1-4/5 lb. cutter features a patented two-step ratchet drive that shears up to 1000 MCM copper, 1000 MCM aluminum, and 2-1/16 in. diameter communication lines without leaving burrs. Outfitted with red plastic-dipped grips, a quick-release blade lever, and a handle-locking latch, this 12-1/8 in. tool enables commercial electricians and utility technicians to perform single-handed cable cuts inside crowded breaker panels, junction boxes, and wireways.

Best Used For:

  • Commercial Main Service Feeder Sizing: Shearing 1000 MCM copper and 1000 MCM aluminum feeder conductors square for distribution panel terminations.
  • High-Density Communication Cable Trimming: Slicing 2-1/16 in. diameter multi-pair communication lines and wire bundles cleanly without crushing outer jackets.
  • Single-Handed Panel Maintenance: Executing high-torque manual cuts with one hand while positioning conductors in narrow junction boxes and meter bases.

Key Performance & Safety Features

  • High-Capacity Cable Shearing: Precision-ground induction-hardened steel blades slice through 1000 MCM soft copper, 1000 MCM aluminum, and 2-1/16 in. communication cable.
  • Patented Two-Step Ratchet Mechanism: Advanced gearing requires fewer strokes per cut, decreasing required hand force and user fatigue during high-volume service.
  • Single-Handed High-Leverage Design: Compact 12-1/8 in. frame profile supplies maximum mechanical leverage for effortless one-handed operation in tight quarters.
  • In-Process Quick-Release Lever: Safety trigger opens blades immediately in any position to adjust placement or remove cable mid-cut.
  • Ergonomic Plastic-Dipped Handles: Textured handle coating provides a firm, slip-resistant hold for increased user control during high-force applications.
  • Safety Handle Locking Latch: Dedicated locking lever keeps handles securely closed for safe transport and storage in tool pouches and bags.

Pro-Tip: When using the Klein 63750 cutter on heavy 1000 MCM copper cable, engage the two-step ratchet using steady, full handle strokes until the moveable blade bites into the jacket. Once the jaw is engaged, keep the cable centered in the blade throat to maintain maximum mechanical leverage and deliver a burr-free square cut.
