The WILLIAMS COMFORT PRODUCTS 3845-18-100P-BULK is a bulk-pack carbody hacksaw blade measuring 3.5 inches in length with an 18 teeth-per-inch (TPI) tooth configuration. These short-length blades are designed for cutting through automotive body panels, sheet metal, and thin-gauge materials where a standard 12-inch hacksaw would be too large to maneuver. The 18 TPI count delivers a balance of cut speed and finish quality suited to ferrous and light non-ferrous sheet stock. This bulk pack contains 100 blades, making it a practical supply option for shops and service fleets that go through blades at high volume.
These carbody blades are used in automotive body work, HVAC duct fabrication, and general sheet metal cutting tasks. The short 3.5-inch format fits compact or pistol-grip hacksaw frames commonly used in confined spaces such as engine bays, wall cavities, and tight mechanical rooms. Trade professionals including auto body technicians, HVAC installers, and general maintenance mechanics will find this bulk quantity useful for stocking a tool crib or service van.
Designed as an OEM-style replacement blade for compact and carbody hacksaw frames that accept 3.5-inch blades.
Blade installation and replacement should be performed with the tool unpowered and the workpiece secured. Follow the hacksaw frame manufacturer's tensioning guidance when seating the blade. Wear appropriate hand and eye protection when cutting sheet metal, as burrs and chips can cause injury. Dispose of spent blades in a puncture-resistant sharps container.
