Bsc Preferred 176178 Keyhole Saw 4 Blade Position

Product Description

The BSC PREFERRED 176178 is a keyhole saw designed for cutting thin sections of solid and tubular stock. It ships with two alloy tool steel blades, including a metal-cutting blade suited for material ranging from 0.125 inches to 0.25 inches thick. The quick-change pistol grip handle allows the blade to be set in four positions, locking both vertically and horizontally to adapt to confined work angles. This tool is built for trade professionals and knowledgeable DIYers who need a compact, versatile saw for hand-cutting tasks in tight spaces.

The 176178 keyhole saw is used in applications where a full-size handsaw or reciprocating saw cannot reach. Typical uses include cutting access holes, trimming pipe lagging, notching framing members, or working in confined mechanical spaces. The metal-cutting blade makes it practical for light sheet metal, thin-wall tubing, and similar stock encountered in HVAC, plumbing, and general mechanical work. The included standard blade extends its use to wood and drywall substrates.

Installation Notes

Ensure the blade is fully seated and locked in position before beginning any cut. When cutting near energized electrical components or pressurized lines, de-energize circuits and isolate or depressurize lines per applicable NEC, IPC, or IFGC requirements before starting work. Use appropriate personal protective equipment including cut-resistant gloves when handling or changing blades. Blade changes should be made with the tool at rest and secured.
