Crescent 0390FC Fiberglass Bolt Cutter
The Crescent 0390FC is a heavy-duty, 36-1/2 inch hand-operated bolt cutter engineered for professional industrial and construction applications. It features all-purpose jaws with center-cut blades for efficient slicing through various metals, paired with lightweight fiberglass handles that reduce overall tool weight without compromising structural integrity.
A specialized toggle joint mechanism significantly magnifies applied force, converting 50 pounds of hand pressure into a massive 4,000 pounds of cutting pressure. For precise operation and sustained longevity, a built-in lock plate prevents the jaws from loosening under heavy tension, while a screw-type adjustment mechanism allows operators to easily realign the cutting edges when necessary.

Frequently Asked Questions
Q: What is the maximum cutting capacity of the Crescent 0390FC?
A: The tool can sever soft and medium materials up to 9/16" thick, and hard materials (up to Rockwell C48 or Brinell 455 hardness) up to 7/16" thick.
Q: How does the toggle joint improve cutting efficiency?
A: The integrated toggle joints provide a substantial mechanical advantage, turning 50 lbs of manual hand pressure into 4,000 lbs of cutting pressure at the blades.
Q: How do I realign the cutting edges on the 0390FC if they shift?
A: The cutter features an integrated screw-type adjustment that allows you to easily realign the jaw edges for optimal, clean cuts.
Q: Is this bolt cutter safe for live electrical applications?
A: No. Despite featuring fiberglass handles, this tool is strictly non-insulated and must never be used on energized circuits, wire, or cable.
