Fernco qs7x6hs 7 Inch Od X 6 Inch Deep Hole Saw

Product Description

The FERNCO qs7x6hs is a 7-inch outer diameter, 6-inch deep hole saw with included arbor, built for cutting large-diameter openings in pipe chase walls, floor plates, and similar rough-in applications. The extended 6-inch cutting depth allows the saw to pass through thick framing members or layered materials in a single pass. At 5.60 pounds, the unit has the mass to resist deflection during aggressive cuts. Plumbers and drain-waste-vent installers reach for this tool when standard-depth hole saws fall short of the required penetration depth.

This hole saw is suited for residential and light commercial rough-in work where large-diameter penetrations are required through wood framing, sub-flooring, or similar substrates. The arbor-included configuration means the tool is ready to mount to a standard drill or hole-saw driver without sourcing a separate mandrel. It is commonly used when running 6-inch or larger drain lines, vent stacks, or sleeve openings through structural members.

Key Features

• 7-inch outer diameter cutting size for large-bore penetrations
• 6-inch cutting depth clears thick framing and layered substrates in one pass
• Arbor included — mounts directly to compatible drill without additional hardware
• 5.60-pound construction provides stability and resistance to bit walk during cuts

Compatibility

Designed for use with standard hole-saw-compatible drills and drivers accepting arbor-mounted hole saws of this diameter class.

Installation Notes

This tool is typically used by licensed plumbers during rough-in framing stages. Ensure the drill or driver is rated for the torque demand of a 7-inch hole saw before use. Confirm that structural members being cut do not carry load paths that require notching or boring permits under local building codes before proceeding. Disconnect power to any nearby electrical circuits that may run inside the framing cavity being penetrated.
