The 1\/2-20 threaded connection provides a secure interface between the drill and the hole saw, reducing wobble and improving cut accuracy. At 0.17 pounds and 5.25 inches in length, the ARB-2 is a compact, lightweight addition to any tool kit. Electricians, wire and cable installers, and switchgear technicians rely on this arbor for repetitive hole saw work where consistent engagement and quick bit changes matter.\u003c\/p\u003e\u003cp\u003eThe ARB-2 is suited for electrical, lighting, and general trade applications where hole saws in the 9\/16 to 1-3\/16-inch range are regularly used.
