Rack-a-tiers 91720 Co-pilot Arbor Attachment Hole Saw

Product Description

The RACK-A-TIERS 91720 is an arbor attachment designed to work with hole saws, giving electricians and other trade professionals a more controlled and efficient way to drive hole saws through wood, metal, and other structural materials. The Co-Pilot arbor attachment connects a hole saw to a drill or driver, helping maintain alignment and reduce bit wander during the cut. This type of accessory is commonly used during rough-in work where multiple penetrations are needed in studs, joists, or panels.

The 91720 is suited for use in residential and light commercial electrical, plumbing, and HVAC rough-in applications. It is typically used by electricians running conduit or cable, plumbers boring through framing for supply and drain lines, and HVAC technicians cutting duct or equipment openings. The arbor attachment helps keep the hole saw centered and stable, which is especially useful when working in confined spaces or overhead.
